Welcome to the Speech Motor Systems (SMS) lab at the University of South Florida directed by Dr. Supraja Anand!
Our research focuses on evaluation of speech sensorimotor deficits in healthy and disordered populations. Identification and monitoring of such signals as a result of aging and neurodegenerative diseases such as Parkinson disease could facilitate early identification, better understanding of the disease progression, and give rise to improved treatment methods.
News & Updates
National Academy of Inventors
Dr. Anand was one of the nine USF faculty to be named as senior members of National Academy of Inventors.
Research Grant Collaborations
Dr. Anand, in collaboration with Drs. Dimitar Deliyski (Michigan State University, MSU; Principal Investigator), Stephanie Cotton (Mayo Clinic), David Eddins (USF), Rahul Shrivastav (University of Georgia, UGA) seek to discover and quantify physiological mechanisms underlying normal and abnormal vocal fold vibratory behavior and establish their relationships to voice quality perception in connected speech. This NIH-NIDCD R01 application began on August 1, 2022!!
Best Paper Awards
Research on dysphonic voice quality perception won two 2021 Best Paper Awards from the Journal of Voice in two categories.
These awards are voted on by the Editorial Board and acknowledge excellence in voice research.

Using pitch height and pitch strength to characterize Type 1, 2, and 3 voice signals. Journal of Voice, 35(2), 181-193.
2. Paper on "Developing clinically relevant scales of breathy and rough voice quality." in the Speech-Language Pathology/Vocal Pedagogy category. Eddins, D. A., Anand, S., Lang, A., & Shrivastav, R. (2021). Developing clinically relevant scales of breathy and rough voice quality. Journal of Voice, 35(4), 663-e9.
NIH R01 Award with ASSL on Voice Quality in Adults
In a new five-year project, titled “A Comprehensive Psychoacoustic Approach to Voice Quality Perception”, Drs. David Eddins, Supraja Anand , Erol Ozmeral, and Jeff Williams will work with colleagues at University of Georgia (UGA; Rahul Shrivastav) and Medical University of South Carolina (MUSC); Dr. Heather Shaw Bonilha) to transform dysphonic voice quality assessment in clinical practice and in research by establishing new psychometric scales that accommodate sustained phonation and connected speech. This 2.8M research study led by Dr. Eddins is sponsored by National Institute of Deafness and other Communication Disorders (NIDCD) began Summer 2021.
NIH R01 Award with ASSL on Pediatric Voice
In a new five-year project, titled “Pediatric dysphonia: Multidisciplinary advances to improve voice quality outcomes”, Drs. David Eddins, Supraja Anand , Erol Ozmeral, and Jeff Williams will work with colleagues at University of Georgia (UGA; Rahul Shrivastav) and Cincinnati Children’s Hospital Medical Center (CCHMC; Drs. Alessandro de Alarcon; Barbara Weinrich, Susan Baker Brehm, Lisa Kelchner) to better understand voice quality associated with pediatric voice disorders. This 2.3M research study led by Dr. Eddins is sponsored by National Institute of Deafness and other Communication Disorders (NIDCD) began Summer 2020.

The second paper won the 2019 Journal of Voice Best Paper Award
These awards are voted on by the Editorial Board and acknowledge excellence in voice research.
Invited talk at the International Congress on Acoustics
Dr. Anand and Desi Gutierrez will be presenting their research on "Effects of background noise on acoustic-perceptual correlates of voice" at the 23rd International Congress on Acoustics, Aachen, Germany (Sep 9-13, 2019).
Faculty International Travel Grant
Dr. Anand was awarded a travel grant to present her invited talk on "Effects of background noise on acoustic-perceptual correlates of voice" at the 23rd International Congress on Acoustics, Aachen, Germany (Sep 9-13, 2019).
New Investigator Research Grant
Dr. Anand awarded a research grant: A grant proposal submitted to the USF New Investigator Research Award has been funded. This proposal compares the similarities and differences between speech and hand function in people with and without Parkinson's disease.
