Prof. Ofer Amir is a Speech-Language Pathologist, who specializes in stuttering and voice disorders. Between the years 2014-2017 he served as the Head of the Department of Communication Disorders, and currently he is a senior factuly member at the department.

Additional information is available is Prof.  Ofer Amir's Personal website:



After completing his undergraduate (B.A.) and graduate (M.A.) studies in the Department of Communication Disorders, Tel-Aviv University, Prof. Ofer Amir has earned his doctoral degree (Ph.D.) in Speech and Hearing Science, from the University of Illinois (U.S.A.) in 1998. During the years of 2014-2017 he was the Head of the Department of Communication Disorders at Tel Aviv Universtiy, where he currently teaches, supervises and conducts research.


In addition to his academic activities, Prof. Ofer Amir runs a private practice, where he diagnoses and treats people-who-stutter and people with various voice disorders. Furthermore, Prof. Amir volunteers, as a senior speech-therapist, at the Speech and Hearing Center, and at the Voice Clinic, at the Sheba Medical Center (Tel-Hashomer).


Prof. Ofer Amir's research, as well as clinical interest, focuses on two major fields: Stuttering and Voice.

In the area of stuttering and other fluency disorders, Prof. Ofer Amir is interested in identifying, quantifying and measuring various fluency charcteristics, as well as providing normative data on speaking rate in Hebrew and exploring therapeutic approaches for stuttering, cluttering and other related fluency disorders. To this end, Prof. Ofer Amir is conducting studies on the perception of stuttering, and on the acoustic properties of speaking rate, normal disfluency and stuttering. In addition, Prof. Ofer Amir is collaborating with researchers in other research centers, utilizing advanced methods for brain imaging related to stuttering and and language.

In the area of voice and voice disorders, Prof. Ofer Amir is highly interested in characterizing vocal properties related to different physical, physiological and emotional conditions, and in professional voice. This line of research involves exploring and identifying acoustic, aerodynamic, percpetual and acoustic measures that differentiate, for example, between people with and without laryngeal pathologies, people who experience various emotional or social conditions, and people at different hormonal conditions and phases (e.g., using birth-control pills, IVF, etc.).
