The Department is one of the core technical departments of this Institute which was established on 9th August 1983, the day on which the Institute was established and has been functioning efficiently since then. The department is one of the core technical departments of the Institute and has contributed in a myriad of ways enhancing the progress of the Institute during the past 30 years. Contributions and activities of the department comprise of clinic and consultancy services, manpower development, in house and extra mural research, community awareness programs, short term training programs and material development.

In addition to providing assessment and (re)habilitation services to the one of the most recent and advanced unit of the Institute viz. Cochlear Implant Unit (Dept. of Audiology), the Clinic of the Department has two Specialized Unitsviz. Voice Unit for Individuals with Voice disorders and Unit for individuals with Cleft lip and/or palate. Recently, i.e. in January 2012, an important unit was added viz. Unit for assessment and rehabilitation of individuals having swallowing disorders. The most outstanding feature of these Specialized Units of the Clinic is that they are well equipped with instruments which are recent, advanced and have the state-of-art technologies.

In addition to the aforementioned Specialized Units, the various sub-sections of the Department of Speech and Language Pathology include Diagnostics, Therapeutics, Group Therapy Unit (especially for children with hearing impairment), Speech Science Laboratory, Recording room and Speech Therapy Park.

The major objectives of the department go hand in hand with the objectives of the Institute and are as follows

The objective assessment and intervention is done with the help of the instrument Digital Accelerometry for Swallow Imaging (DASI, Elixir Research, USA)

Manpower development

Trained skilled manpower is essential for conducting diagnosis and for providing rehabilitative services. In the country there is a paucity of trained professionals to deal with the above.Hence, to fulfill such needs the Institute provides various under graduate and post graduate courses in the area of speech, hearing and education of hearing impaired and other speech-language disorders. These include BASLP, MASLP, B.Ed(HI), M.Ed (HI). Department contributes immensely in preparing this manpower by providing in-depth training both theoretical and practical to the students enrolled.

Similarly, the Department also conducts short term RCI recognized CRE programs / workshops within Mumbai and in any part of the country, for DHLS, BEd(HI) professionals. The duration of the program/workshop is between 3 to 5 days. One short term training program focuses on speech problems of hearing impaired, whereas, the other program focuses on any other speech/language disorders and is designed for Master trainers.
