Department of Speech and Hearing Science rose from a humble start

As humble beginnings go, it would be difficult to top that of the Department of Speech and Hearing Science at the University of Illinois.

In 1938, Dr. Severina E. Nelson repurposed a closet in Lincoln Hall to start an outreach program providing speech therapy. She began by assisting a student with some articulation difficulties. Sharing an office with colleagues and unable to find a private room, Nelson said, “Finally, the janitor volunteered to donate his mop closet so that I could set up a speech therapy lab. He moved to the basement.”

If that were all there was to it, Nelson would go down in campus history as one of the more determined, innovative, and resourceful professors at Illinois and as a founder of what, in 1973, became the Department of Speech and Hearing Science (SHS).

But there is more to Severina Nelson, and SHS, than that.

“Nowadays, our culture is notoriously rough on the dedicated person with a cause, especially a woman,” wrote a group of students to Nelson upon her retirement in 1964. “It is true that all new concepts only get recognition after someone has spent years being persistent and farsighted until finally, the disbelievers are made uncomfortable and become believers. You’ve been a woman with a gleam in your eye, and thank heaven, you never became a casualty of our system.”

Nelson earned her B.S. in 1918 and her M.A. in 1923 in English at the University of Illinois at Urbana-Champaign. She began her professional life as a high school teacher in Iowa, coming back to Urbana-Champaign in 1920 as an associate instructor in the Division of Public Speaking in the Department of English. After earning her M.A. degree, she pursued a career teaching interpretive speech. She was an engaging speaker, giving countless readings for campus groups, on tours across Illinois, and on radio shows. This led to her co-authoring a best-selling speech textbook with Charles H. Woolbert in 1927: The Art of Interpretive Speech (with a fourth edition still in press in the 1960s).

In 1932, Nelson was elected president of Sigma Delta Phi, a national honorary women’s dramatic and speaking fraternity. Fittingly, it was Nelson who introduced aviator Amelia Earhart during her March 21, 1935 appearance on campus—two years before Earhart’s disappearance. Nelson had built a profile as a director of dramatic productions, including those for the Women’s League, the annual Homecoming “Stunt Show,” and the Hillel Players.

Nelson earned her Ph.D. in 1938 in Speech Pathology at the University of Wisconsin in Madison and then did post-doctoral work at the New York Medical College. The work Nelson began by helping college students with speech difficulties received funding and was then extended to community members. In 1938, she brought clinical practice at the University of Illinois into existence by establishing its speech clinic, serving as its director from 1939-59 and as a professor of speech from 1941-64. Some of Nelson’s early research in speech disorders focused on stuttering. She published three seminal articles from 1939-45 in the Quarterly Journal of Speech and The Journal of Pediatrics, on the role of heredity in stuttering, and in the Journal of Speech Disorders, on stuttering in twin types.

In 1939, the Daily Illini described Nelson as “one of the most popular instructors in summer school,” noting that “her office is different from the usual. Here you open the door and find yourself looking into a full-length mirror. Vanity isn’t the reason for the mirror’s being there. She finds it very useful in her speech correction work. Just during the past year, the speech department has made great advances in this work, and much of it has been under Miss Nelson’s supervision. Patients are studied and classified according to their type of speech defect, then they are turned over to students in speech correction classes for help.” (Please see Editor’s Note below regarding terminology use in historical records) Most of the student therapists were women whom Nelson supported as the faculty advisor to the campus chapter of Zeta Phi Eta, the national women’s speech sorority.

By 1940, Nelson had secured a $2,000 grant to support her clinic and extensive office and clinical space in Gregory Hall, where individuals with cerebral palsy, hearing disabilities, and cleft palate received therapy. She also had established an educational program in speech therapy at the University of Illinois, with four years of undergraduate coursework and one year of graduate study. From 1943-1944, as the chair of a state legislative committee, Nelson delivered 50 to 75 speeches throughout Illinois to win passage of the committee’s bill to provide supplemental funds for local clinical efforts. With the onset of the World War II, veterans were returning with “organic and psychological disabilities.” The clinic’s funding from the farsighted bills in the Illinois legislature was augmented by federal assistance to veterans. Twenty-seven nationwide colleges and universities received this funding, notably clustered in the Midwest around the University of Illinois, including Indiana University, Northwestern University, the University of Michigan, and several branches of what would become the University of Wisconsin system.

The demand for speech and hearing specialists was such that Nelson wrote to her department head in 1945 that the University of Illinois Speech and Hearing Clinic was competing against Army and Navy hospitals to recruit therapists for work in the Champaign and Urbana school districts. By 1946, there had been 16 master’s theses recorded in Speech and Hearing Science.

In 1950, under Nelson’s leadership and advocacy the clinic moved to the Lorado Taft House on campus (though, as she wrote in a letter, Nelson was convinced the University planned to demolish the building.) The St. Louis Post-Dispatch reported that “her enthusiasm, plus a brisk business-like air, are reflected in the rest of her efficient and enthusiastic staff.” A newsletter describing “Dr. Severina Nelson’s informative, vivid, and impressive account of the Illinois Speech Clinic” to the Urbana Rotary Club in January 1955 noted that “Professor Nelson filled her talk with case histories … all interesting. Urbana Rotary played a large part in sparking the state’s program—a program which for some years has been one of the best in the Union.”

When Nelson stepped down as director of the speech clinic in 1959, it had 10 full-time therapists. She resumed full-time teaching in speech pathology and oral interpretation, and by then, had advised more than 125 graduate theses. With her national renown, she was often requested as a speaker by groups and organizations across the country. After retiring in 1964, Nelson moved to Dallas and in 1978, received Honors of the Association from the Illinois Speech-Language-Hearing Association.

Editor’s Note: As in many fields, perspectives and terminology in speech and hearing science (also called communication sciences and disorders) have evolved over the years, away from those appearing early in the historical record. For example, our focus has shifted away from correcting a person’s speech defects toward improving the intelligibility of their speech and enhancing the effectiveness of their communication with others.

CHAD symposium returns with thanks for pilot grants



KCH Associate Professor Naiman Khan’s presentation was titled “Role of Omega-3 Lipid Metabolites in Obesity and Cognitive Function” (Photo by Lisa Bralts)

The first Center for Health, Aging, and Disability (CHAD) symposium since 2017 was a celebration of the research accomplished with the help of the Pilot Grant Program.

Three researchers from the College of Applied Health Sciences—Naiman Khan, an associate professor in Kinesiology and Community Health; Brian Monson, an assistant professor in Speech and Hearing Science, and Sharon Zou, an assistant professor in Recreation, Sport and Tourism, made a point of thanking CHAD’s grants for helping launch their studies.

Khan, whose presentation was titled “Role of Omega-3 Lipid Metabolites in Obesity and Cognitive Function,” said CHAD’s funding was vital to his work.

“CHAD was really helpful in us starting a new line of engagement of research,” he said. 

CHAD director Jeff Woods, AHS’ associate dean for research, said to date, 38 pilot grants have been awarded since CHAD was launched in 2010, with $860,000 awarded to AHS researchers for pilot research. Woods described CHAD’s role as “work at the bookends of medicine … with the goal of improving people’s lives.”

“CHAD pilot grants are really important for junior faculty,” Zou said.

And the payoff has been well worth it, Woods said, citing the return on investment as approximately $16 in external funding to $1 in CHAD funding. 

Zou’s presentation was titled “Exploring an Efficient and Equitable Entrance Fee for Public Lands: A Community-based investigation in the Indiana Dunes National Park.”

“I study how people have fun,” Zou said, explaining that it was vital for public parks and other tourism industries to build a sustainable revenue model and not to rely on decreasing funding from state and federal sources. 

The primary purpose of Zou’s study was to “understand visitors’ and surrounding community residents’ perceptions of Indiana Dunes National Park user fees to inform a fee structure that balances revenue generation and equitable access.”

During and after the COVID-19 pandemic, Zou said, “parks saw explosions of people visiting.” While that was great for parks in terms of revenue, it also led to increasing operation costs at a time when government funding for these sites is being reduced.

“The specific goal is to find out how visitors see the park fees, and are they fair?,” Zou said.

The RST researcher said her preliminary findings indicate there was no consensus from study participants on what “fair” means, and that tension between fairness principles partly explains the longstanding controversy and debate on public land user fees.

Khan’s presentation focused on how poor lifestyle choices can predict an early onset of dementia, noting that obesity worldwide has increased threefold since the 1980s. The KCH researcher said his research, in conjunction with Aditi Das of Georgia Tech, suggested that the a deficiencyin the hormone dehydroepiandrosterone (DHEA)—which has been reported to have beneficial effects on obesity, diabetes mellitus, and serum lipids in animals—was associated with individuals with a body-mass index (BMI) of 25 or higher, which is classified as obese.

“BMI is inversely connected to cognitive function,” Khan said. “Only in obese individuals do we see DHEA increase in circulation.” Khan said his preliminary results found:

  • Circulating Omega-3 metabolites were higher among persons with higher weight status and the levels were associated with degree of fat mass
  • Circulating metabolites inversely associated with cognitive function
  • Only observed among persons with overweight and obesity
  • Selectively associated with hippocampal function
  • Implications for memory function

Khan said his overarching goal was to “develop effective lifestyle approaches to improve cognitive function.”

SHS’ Monson discussed his study called “Capturing Prenatal Auditory Experience.”

“If there was a pregnant woman in this audience, that baby would be hearing my voice, and perhaps making judgments,” he said, drawing laughter from the gathering. “How do we know? Because full-term newborns come to the world with memories of what they’ve heard, including the mother’s voice.”

In utero, Monson explained, was a unique acoustic environment. When preterm infants are delivered, they are placed into incubators, which rapidly changed the sound profile, he said. The consequences of those changes include increased risk for sensorineural hearing loss, auditory neuropathy, language and speech developmental delays, auditory attention deficits and auditory processing disorder.

Monson’s study involved a group of pregnant women wearing a LENA listening device twice a week during the third trimester, while the device was placed into cribs of very preterm infants at Carle Foundation Hospital three times a week through their stay in a neonatal intensive care unit (NICU).

“Fetuses are getting 2.5 hours a day of speech exposure vs. 32 minutes a day for very preterm infants,” he said. “It’s an alarming difference to me.”
NICU infants may incur a deficit of about 150 hours of speech exposure over the course of the preterm period, he explained.

One of the possible mitigation strategies for very preterm infants could be to provide meaningful targets (about three hours a day of speech exposure) to optimize auditory exposures in NICU settings.

“The maternal heartbeat is never turned off in utero,” he said. “The maternal heartbeat is never turned on in NICU.”

Following the CHAD Pilot Grant success stories, Wendy Rogers, the Shahid and Ann Carlson Khan Professor of Applied Health Sciences, talked about the work of Collaborations in Health, Aging, Research, & Technology (CHART).

CHART’s mission is to enable successful aging through:

  • Fundamental research
  • Advanced technology development
  • Education of researchers, developers, healthcare professionals, older adults
  • Guidance for policy decision-making
  • Translation of these efforts to positively affect the lives of older adults

CHART was the first research theme of the College of Applied Health Sciences and boasts the development of the McKechnie Family LIFE Home, an interdisciplinary research facility and simulated home environment that helps promote community engagement, industry partnerships, healthcare collaborations and faculty innovation.

Also part of the symposium was the introduction of a new AHS research theme called CARD (Collaborations in the Advancement of Research on Disability), led by KCH Associate Professor Laura Rice and KCH Professor John Kosciulek. CARD is focused on enhancing the health and quality of life of people with disabilities—through research that addresses critical gaps in disability-related knowledge and outreach that engages individuals with disabilities. 

CARD’s short-term goals include:

  • Develop a collaborative working group
  • Develop communication strategies
  • Establish a steering committee of stakeholders
  • Develop and implement outreach and engagement events

Longer-term goals include:

  • Host a bi-annual research symposium
  • Develop a “toolkit” for UIUC faculty to support the performance of disability-related research in the Champaign-Urbana area
  • Respond to disability-related funding opportunities
  • Establish a competitive program to provide supplemental funding to support ongoing disability research among junior faculty
  • Host a seminar series with external experts
  • Establish a research training program for students registered with DRES interested in doing research
  • Support the development of new research registries and/or expansion of current registries

The first CARD meeting is set for March 22.

In kicking off the symposium, AHS Dean Cheryl Hanley-Maxwell said CHAD was “one of the biggest attractions” of her decision to come to Illinois and lead the college.

“When I thought about CHAD, I thought it’d be interesting to lead a college that has this kind of momentum to it, and I’ve been proven correct, year after year,” she said. “CHAD provides students with real-world engagement, and plays an absolutely critical role in their professional development.”

Woods agreed.

“We’re helping put the next generation of scientists into the field.”

2023 AHS Distinguished Lecturer Series—Dr. Travis T. Threats



Saint Louis University Speech, Language and Hearing Sciences Chairperson Travis Threats. (Photo provided)

About the Presentation

In looking at different populations, it is important to distinguish between differences and disparities. With a differences orientation we look at the population’s own perceived strengths and areas of wanted improvement. With the disparities orientation, we view the “winners” and “losers” of “the system.” Looking at aggregate group differences also obscures the wide within group variation a given population. Thus, even disparities research and thought can have implicit biases. In this presentation, the World Health Organization’s International Classification of Functioning, Disability, and Health (ICF) will be used as a framework and classification system to take a more comprehensive and person-centered view of the wide variety of health indicators within any given population.

About Dr. Threats

Travis T. Threats, Ph.D. is Professor and Chair of the Department of Speech, Language & Hearing Sciences at Saint Louis University. His primary scholarly work has been with the World Health Organization (WHO) on the International Classification of Functioning, Disability and Health (ICF). He has been the American Speech-Language-Hearing Association’s (ASHA) representative liaison to the WHO since 1999. He has worked on other projects for WHO including the disability sections of the ICD-11. Dr. Threats has also published and presented internationally on his three other scholarly interests: spirituality/religiosity in rehabilitation, evidence-based practice, and rehabilitation ethics. Dr. Threats is an ASHA Fellow and ASHA 2012 recipient of the Certificate of Recognition for Outstanding Contributions in International Achievement. He is a Distinguished Scholar and Fellow of the National Academies of Practice. In 2022, he was awarded Honors of the Association by the American Speech-Language-Hearing Association (ASHA), the highest honor given by ASHA.

New AI institute to focus on the speech language pathology needs of children



The University of Illinois is part of a nine-university consortium led by the University of Buffalo that has been awarded a $20 million grant by the National Science Foundation to establish a national institute that develops artificial intelligence systems that identify and assist young children with speech and/or language processing challenges. The award will establish the AI Institute for Exceptional Education to advance foundational AI technologies, human-centered AI design, and learning science that improve educational outcomes for young children. 

The institute will help address the nationwide shortage of speech-language pathologists and provide services to children ages 3 to 10 who are at increased risk of falling behind in their academic and socio-emotional development – issues exacerbated by the COVID-19 pandemic.

Pamela Hadley, professor and head of the Department of Speech and Hearing Science at the University of Illinois Urbana-Champaign, is one of the co-principal investigators for the grant. 

“In light of the shortage of speech-language pathologists nationwide, there is a pressing need to develop health technologies that can help identify young children at-risk for speech and language disorders at younger ages and do so more efficiently,” said Hadley, a fellow of the American Speech-Language Hearing Association. “Our multidisciplinary team will enhance automatic speech recognition systems, improving early identification and interventions for children with developmental language disorder and other conditions that affect speech and language. Our team will also create advanced artificial intelligence systems that will support tailored interventions for children on the caseloads of speech-language pathologists. By doing so, we will create educational environments that help children thrive socially and academically.”

Institute will help underserved students

The AI Institute for Exceptional Education will focus on serving the millions of children nationwide who, under the Individuals with Disabilities Education Act, require speech and language services.
Specially, it will develop two advanced AI solutions: the AI Screener for early identification of potential speech and/or language disorders; and the AI Orchestrator, which will act as a virtual teaching assistant by providing students with ability-based interventions.

The AI Screener will listen to and observe children in the classroom, collecting samples of children’s speech, facial expressions, gestures and other data. It will create weekly summaries of these interactions that catalogue each child’s vocabulary, pronunciation, video snippets and more. These summaries will help teachers monitor their students’ speech and language abilities and, if needed, suggest a formal evaluation with a speech-language pathologist.

The AI Orchestrator is an app that will help speech-language pathologists, most of whom have caseloads so large that they must provide group-based interventions for children instead of individualized care. The app addresses this by recommending personalized content tailored to students’ needs. It continues to monitor students’ progress and adjusts lesson plans to ensure that the interventions are working.

“The AI Institute for Exceptional Education follows 18 already established NSF-led AI Institutes, an ecosystem of AI research and education in pursuit of transformational advances in AI research and development of AI-powered innovation,” NSF Program Director James Donlon said. “We are happy to welcome this new team to the AI Institutes program.”

Institute comprises top research universities

The institute will consist of more than 30 researchers from nine universities including the University of Buffalo; Stanford University; the University of Washington; Cornell University; the University of Nevada, Reno; the University of Texas at El Paso; Penn State University; and the University of Oregon.

Other investigators at Illinois are Heng Ji (Computer Science), Mark Hasegawa-Johnson (Electrical and Computer Engineering), Yun Huang (Information Science), Hedda Meadan-Kaplansky (Special Education), and Windi Krok (Speech and Hearing Science).

“We are eager to see how this team advances AI research to develop better solutions for children with specific speech-language needs, as well as their families and the U.S. schools who serve them. This project is a great example of how we can harness the opportunities that AI technologies can offer to enhance the services that our nation can offer the American people,” NSF Program Director Fengfeng Ke said.

SHS audiologist ‘hopeful’ about hearing aid ruling



After a recent FDA decision, hearing aids are now available over the counter.

A decision by the Food and Drug Administration that permits hearing aids to be sold without consulting a medical professional could be a positive development, Speech and Hearing Science audiologist Sadie Braun said.

But, as she’s fond of saying, consumers might have to “play it by ear”.

The FDA ruling, which was finalized in August and took effect on Oct. 17, allows adults with mild or moderate hearing loss to purchase a hearing aid without prescription. The ruling will create more competition and lead to quick technology advancements and lower device costs, but without FDA approval a company cannot classify its product as a “hearing aid.” Per the FDA, the devices covered are air-conduction hearing aids, which fit either in the ear canal or sit behind the ear. Other types of hearing  devices include cochlear implants or bone-anchored systems.

While there are plenty of positives to the new rule, it is important to stress that hearing aids are not a one-size-fits-all proposition, Braun said.

“I am a little nervous about the idea that some people who are self-diagnosing may not actually have a mild-to-moderate hearing loss,” she said. “They might be getting hearing aids that are not ideal for them. More importantly, I’m worried that by removing audiologists and ear, nose, and throat doctors from that process altogether, that patients might not get the care that they need for some of those more significant auditory and medical conditions that can be related to the ears and can be very serious if left untreated, such as acoustic neuromas, and Meniere’s disease, to name a couple.”

Given those concerns, Braun recommends that anyone who is considering trying an over-the-counter device make an appointment with an audiologist for an initial hearing test.

That said, Braun believes the ruling will end up being a good thing for “our patients, for audiology, and for the hearing aid industry on the whole.”

“I think that this legislation definitely opens the door for some of our traditionally underserved and underrepresented populations and communities so that they can obtain devices that can help them hear better that they might not have otherwise been able to obtain,” she said, citing the cost of hearing aids. 

The average price for a pair of prescription hearing aids is $4,600, but OTC hearing aids are expected to cost far less. The federal government estimates Americans could save up to $3,000 on hearing aids by choosing OTC brands rather than prescription devices. If that’s the case, the average cost for a pair of OTC hearing aids would be around $1,600. One wrinkle is that there are now several different devices that can be used to amplify sound for a multitude of purposes: hearing aids and Personal Sound Amplification Products, better known as PSAPs, and it can be difficult for consumers to differentiate them.

“The big difference with PSAPs is that they are not meant to treat hearing loss,” Braun said. “They are actually for normal-hearing individuals only. And they’re therefore not classified as medical devices. Instead, they’re considered electronic products. Because of this, they are not regulated at all by the FDA. One example of something the FDA determines with medical devices is age limitations and requirements, and they have stated that OTC aids are ‘not intended for use by individuals who are younger than 18’.  However, while they say that in the rules and regulations, they do not require age verification before over-the-counter hearing aid purchase. But on PSAPs, for example, there’s no recommended requirement.”

Another benefit of the FDA OTC rules, Braun believes, is they will go a long way toward ensuring safety standards for OTC devices.

“The rules and regulations that took years to develop and fine-tune are critical pieces in this OTC legislation,” she said. “We really have to have those built-in safety mechanisms to protect the consumer, to make sure the consumer does not get injured. Also, we have to make sure that these devices meet a set of standards, a set of criteria, to be sure that they do what they claim they will do, or what they are intended to do. Without those regulations in place, I would be much more wary of recommending OTC hearing aids as an option for some of my patients who have mild-to-moderate hearing loss.”

Still, Braun cautions that in the early stages of the aftermath of the rules, much is yet to be determined, and she stresses the need for professional guidance.

“Each person has a different and unique set of needs,” she said. “Some individuals can navigate that process, on their own and potentially be successful with over-the-counter devices. I think that other individuals really need that guidance of a professional to help them through the entire process from start to finish and to be there for support and assistance the entire way. Over-the-counter hearing aids cut out the service component, and that professional service component is what a lot of patients really rely heavily on.”

One way to access that professional service is through SHS’s Audiology & Speech-Language Pathology Clinic. You can reach clinicians by calling 217-333-2205 or emailing shsclinic@illinois.edu.

Serving the profession through mentorship



Theodora Papastratakos completed her master’s degree in 2015 and her CFY during the 2015-2016 school year, her first with Aldrin Elementary School in Schaumburg.
Theodora Papastratakos completed her master’s degree in 2015 and her CFY during the 2015-2016 school year, her first with Aldrin Elementary School in Schaumburg.

When students take on their first professional position after completing their master’s degrees in speech and hearing science with a focus on speech-language pathology, they must also begin what is called a Clinical Fellowship Year, or CFY, required by the American Speech-Language-Hearing Association (ASHA) to earn the Certificate of Clinical Competence in Speech-Language Pathology (CCC-SLP). The CFY pairs a first-year practitioner with an experienced practitioner in a mentoring relationship designed to ease the transition between student and independent provider of clinical services.

Theodora Papastratakos completed her master’s degree in 2015 and her CFY during the 2015-2016 school year, her first with Aldrin Elementary School in Schaumburg.

“You dive right in, which is why you have a clinical fellowship supervisor,” she said. “It’s so different from being in graduate school and doing your clinical externships versus managing your own caseload. It’s a big leap.”

She found her own CFY experience positive, but also knew there were things she would have liked to change. During her first several years of practice at Aldrin Elementary, Theo felt she was still learning so much that she could not supervise a clinical fellowship. In the fall of 2021, the department head reached out to her to see if she’d be willing to supervise a new SLP who would be joining the school part time.

“I’d been practicing for seven years, and I think I realized that I do know a lot,” she said. “I was excited to share some of that knowledge with somebody coming into the field.”

She took the training course offered by ASHA and welcomed May 2021 University of Illinois Urbana-Champaign SHS graduate Rachel Deichstetter to Aldrin Elementary as her first mentee. Some of Theo’s role involved just being available to Rachel to answer questions, walk her through district policies and procedures, and give feedback on her ideas.

“I would review her goals and the reports that she was writing and help her as needed,” Theo said. “I watched some of her therapy sessions and gave her feedback throughout the year. If she was experiencing something for the first time, I might help a little bit more. Toward the end of the year, she was practicing independently.”

Theo enjoyed assisting with Rachel’s transition from student to professional and working with someone fresh out of graduate school. “It was fun to see her gain more confidence throughout the year,” she said. “Sometimes when you’ve been practicing for a while, you get stuck in what you’re doing. Rachel brought fresh ideas and new ways of doing things.”

Theo will continue working at Aldrin Elementary while Rachel joins another school in the Schaumburg district for 2022-2023. “I’ll remain a resource for her in the future if she has questions or needs to bounce ideas off someone,” she said. She looks forward to her next opportunity to supervise a clinical fellow and mentor another budding speech-language pathologist into the profession.

Oversen’s road to a Fulbright grant was paved by family



When she completes her Fulbright stay, Amanda Oversen plans on applying for graduate school

Amanda Oversen’s interest in linguistics has a very clear inspiration: her mom.

Oversen, a Speech and Hearing Science major who graduated in December 2021, was recently awarded a Fulbright English Teaching Assistantship to Spain. Her goal is to become a bilingual speech-language pathologist for elementary school-aged students.

That makes sense given her curiosity about languages, which she credits to her mother.

“My mom is from Honduras. She immigrated to the U.S. when she was 16. And interestingly enough, she moved to the U.S. because she wanted to learn English. She also has this curiosity about language, which I think kind of rubbed off on me,” Oversen said.

While in Spain, Oversen plans to learn Spanish Sign Language and connect with the local deaf community. She also is interested in how to cultivate cultural-linguistic diversity in the American school system.

“I think when we learn a different language, it opens up just so many doors,” she said. “You’re able to understand people on a different level. I find that really fascinating. I think a lot of that had to do with my mom growing up bilingual, too.”

Oversen, who is from Highland Park, Ill., served as a teaching assistant in the Child Development Laboratory in SHS, which amplified her desire to work with children.

“I loved how curious kids were, and how everything was new to them, how the tiniest thing—something that comes so commonly to adults—was mind-blowing to kids,” she said. “I just love the fascination that they had with things that adults take for granted. I think it would just be cool to help kids progress, and find confidence in their voice, despite the fact that they may have a speech or a language disorder.”

Picking Spain for her Fulbright application was an easy choice. Spanish was spoken in her childhood home, and she studied abroad in southern Granada during her sophomore year. Teaching in Spain has a family connection as well, as Oversen’s brother went there to teach English.

This time, Oversen will be stationed in the Canary Islands.

“The Canary Islands was never really on my radar, so when I found out I was like, ‘Oh my gosh, that’s going to be quite an experience.’ I’ve never lived on an island before.”

Since graduation, Oversen has been working as an assistant teacher at an early childhood education center in Northbrook, Ill. When she completes her Fulbright stay, she plans on applying for graduate school, with the University of Illinois on the list.

“I’ve made kind of a master list of graduate schools. Almost all the schools are in Illinois, and a few out-of-state options. But I think I’d like to stay close to home, whether that be in Champaign or in Chicago.”

Dr. Husain Named McCristal Scholar



Fatima Husain uses magnetic resonance imaging in her research.

Dr. Fatima Husain, professor of speech and hearing science, has been named the 2022 King J. and Marjorie R. McCristal Distinguished Scholar in the College of Applied Health Sciences, the most prestigious recognition of scholarly achievement given by the College. The award presentation and McCristal Lecture will take place on August 16, 2022, as part of the AHS Fall College Meeting.

Dr. Husain joined the Department of Speech and Hearing Science as an assistant professor in 2008. She earned her PhD in cognitive and neural systems at Boston University and joined the National Institute on Deafness and Other Communication Disorders, part of the National Institutes of Health, first as a post-doctoral fellow and then as a research fellow.

Dr. Husain uses a combination of computational modeling, brain imaging experiments, and behavioral experiments to research hearing and speech perception, as well as the disorders associated with them, such as hearing loss and tinnitus. Through this multi-method approach, she is able to simulate auditory and speech perception in the brain. The modeling enables her to make predictions that can be tested using behavioral and imaging tools, ultimately facilitating the evaluation of existing therapies and the proposal of novel treatment methods. She is the director of the Auditory Cognitive Neuroscience Lab.

The King James McCristal Scholar Award was established in 1988 to honor King McCristal, dean of AHS from 1961-1973.

Bruce Willis’ diagnosis brings aphasia to forefront



Bruce Willis’ aphasia diagnosis went public in April 2022.

Aphasia is a communication disorder that affects understanding and expression. It can make it difficult to speak, write, listen, and read. But despite its dire impact on people, aphasia is not a well-known condition. In fact, according to a 2016 survey by the National Aphasia Association (NAA), less than 10 percent of respondents knew what aphasia was.

But the announcement in April 2022 that Bruce Willis would be stepping away from acting following an aphasia diagnosis has raised awareness of the affliction, said Abby Franz, a speech pathologist and clinical instructor in the Department of Speech & Hearing Science at University of Illinois.

“I feel awful for the family and his situation and that he has that diagnosis,” Franz said. “But in 2016, the NAA conducted a survey and found only 8.8 percent of the respondents knew what aphasia was and correctly identified it as a language disorder. So certainly Bruce Wilson’s diagnosis can bring awareness to aphasia. But it’s common. More than two million people are living with aphasia in the United States, and for only 8 percent of the general population to know what it is and know that it was a language disorder, that’s pretty significant.”

Aphasia is an acquired communication disorder, Franz said, which means that it’s something that happens during the course of a life. It’s not something that is present from birth. It is an acquired neurogenic communication disorder, usually as a result of a stroke or some type of brain injury, she said.

There are many types of aphasia, and they are usually diagnosed based on which area of the language-dominant side of the brain is affected and the extent of the damage.

“Typically, it is something traumatic like a type of traumatic brain injury, either they’ve fallen, they’ve hit their head, they’ve been in a car accident, which has affected the area of the brain that controls our speech and language, or a sudden stroke that has left them with difficulty with speech and language,” Franz said.

“But there is another type of aphasia called primary progressive aphasia. That is a degenerative disease that is caused by a type of dementia—frontotemporal lobe dementia. It isn’t a sudden onset change in language. It’s a gradual deterioration of brain tissue in the frontal lobe of our brain that causes, over time, kind of your language to really deteriorate and comprehension of language to deteriorate.”

Franz did not want to speculate about whether Willis has primary progressive aphasia (PPA), but said what she read about his diagnosis lead her to believe he is afflicted with PPA.

“When you have a stroke, it just happens, like suddenly onset. So there wouldn’t be this gradual deterioration” of what has been speculated to have happened to Willis, she said.

Primary progressive aphasia symptoms are akin to dementia. Franz said, with primary progressive aphasia, there would be difficulty with word finding, difficulty sometimes with even just the production of speech, or more effortful for them to even just formulate a sound. They may have a loss in just the fluency of speech as well as the comprehension of speech.

“Somebody who has primary progressive aphasia, if I showed him (a pen), he or she may not be able to name it, but then they also may not even be able to tell me what it does. So they lose that ability to even know this is a pen and we write with it,” she said.

As a speech language pathologist, Franz said she makes aphasia determinations based on how patients perform on certain tasks during a language assessment.

“We’re also testing their comprehension of language. We’re looking at their ability to follow simple directions, follow two-step directions. And we’re looking also at their ability to write after a stroke or after a brain injury because sometimes those go hand-in-hand with the loss of language.”

That said, an aphasia diagnosis is not always without hope. With the help of rehabilitation intervention provided by a speech-language pathologist, people with aphasia from a stroke or other brain injury can improve. SLPs partner with people with aphasia and their families to improve communication skills and develop strategies to support their communication strengths, and may assist with using an augmentative and alternative communication speech devices for those individuals if needed.

However, Franz speculates that because Willis’ family said the actor would pull back from public appearances, she believes he has primary progressive aphasia, and that the prognosis for that is not promising. According to the NAA, the average life expectancy from onset of the disease is 8 to 10 years.

“It is that dire when you get that diagnosis,” Franz said. “It’s a very slow progression of the loss of their communication and along with this kind of dementia too that goes along with it.”

Talking about PPA is “very personal” to Franz.

“My parents’ best friend was diagnosed with primary progressive aphasia in 2017,” she said. “And he’s still living. I see the professional side of it. But now I’m living it on a personal note. And it’s been very hard.

“When he got the diagnosis, I had to do a lot of education with my family about it, especially my parents. Because this was their best friend, and he’s been a part of my life since I was born. And you know, I had to educate them a lot about what primary progressive aphasia is and what it’s going to look like at the end of life. So that is not a great diagnosis to have. So I understand, for the family, why they are probably wanting to shield Bruce Willis from being in the public eye.”

When a public figure such as Willis is afflicted, it often brings an opportunity to educate people about a disease or medical condition.

“The National Aphasia Association is a great website and a great reference for anybody to learn more about aphasia or just to understand more about what it is, and find support groups, within your local community,” Franz said. “It’s a great reference and website to look for if you have a family member or know somebody who has been given the diagnosis of aphasia.”

SHS World Voice Day shows importance of interaction between voice and acoustic environment



Faculty from the Dept. of Speech and Hearing Science were involved in the planning and execution of World Voice Day, a symposium designed to build awareness of the human voice.

Researchers from SHS—including assistant professors Keiko Ishikawa, Brian Monson and Pasquale Bottalico—as well as invited speakers discussed their interdisciplinary projects illuminating voice usage and health.

At the end of the two-hour-plus event, the consensus to achieve voice clarity was: The room matters.

One of the presentations was a collaboration of Bottalico, School of Music Associate Professor Yvonne Gonzales Redman and undergraduate student Natalia Łastowiecka, who worked on a study investigating the influence of room acoustics on singers’ voice production. Clarke University Assistant Professor of Music-Voice Joshua Glasner was also part of the presentation.

The researchers said that similar research on instrumentalists suggests that musical performers may be influenced to some extent by the acoustic environment, and this study demonstrates that singers also tend to adjust their vocal production when in different spaces. Bottalico said singers were recorded singing the same musical selection—Giuseppe Giordani’s “Caro mio ben”—consecutively in five different locations on campus: Smith Memorial Room, Smith Recital Hall, KCPA Great Hall, Colwell Playhouse and the Amphitheater. Voice parameters analyzed were vibrato rate, extent, and pitch inaccuracy. Vibrato extent showed significant changes to the different acoustic environments.

The researchers said to combat any voice problems, singers should train in a variety of spaces, and that future studies should investigate functional causes of aberrant vibrato rate, and investigate how to train singers to adapt to different acoustic environments.

Dr. Ishikawa presented with Diana Orbelo of the Mayo Clinic on the “Vocal health among singers.” Orbelo talked about the importance of gargling, calling it the “rock-star quick fix.” Orbelo said gargling—she recommended water, not beer, as some rock stars preferred—can quickly relax the voice. Ishikawa talked about The Lombard Effect, which is the involuntary tendency of speakers to increase their vocal effort when speaking in loud noise to enhance the audibility of their voice.

Ishikawa said that noisy environments are difficult for anyone to speak intelligibly but they are more difficult for people with voice disorders. Most of these people undergo voice therapy as a part of their treatment, where they learn to use vocal production techniques.

“We wanted to know which technique most effectively improves intelligibility in noise and found twang was the best one, compared to operatic resonant voice and “clear speech,” she said.

“Because noise changes the way people talk—which is the Lombard effect—we thought it would make it difficult for people to use learned therapy techniques. Our recent study showed otherwise, however. People did better with using a technique called “clear speech” when they were hearing the noise. This finding was unexpected and needs further exploration,” Ishikawa said.

Orbelo added that certain sounds, such as twang, as Ishikawa mentioned or talking like a gangster—think Edward G. Robinson In “The Last Gangster”—can help cut through noisy environments.

Monson’s presentation was on the “Directivity of singing voice.” Monson talked about singers’ need to get accommodated to acoustic spaces because they “rely on auditory feedback to regulate vocal output.”

But directivity of a voice matters as much as reflective surfaces because sounds “don’t necessarily go in all directions.”

Other presenters included Dario D’Orazio from the Universita’ di Bologna, Italy, on the “Auralization of soprano;” lan Howell of the New England Conservatory of Music, who presented on “Spectrographic and perceptual analysis of the singing voice,” and Mary Pietrowicz, a Senior Research Scientist at the Illinois Applied Research Institute, presented on “Application of machine learning for voice quality detection among actors.”
