The Speech and Hearing Group provides a forum for IOA members with an interest in acoustic aspects of speech and hearing. These include speech intelligibility, perception and production, hearing protection, audiology, assistive and other technologies for speech and hearing, and speech and language therapy.

The Speech and Hearing Group committee is active in organising meetings aimed at raising awareness of the subject and advancing technical development through the sharing of knowledge and experience. The group acts as a point of contact for individuals and organisations from all backgrounds that share the common interest, and welcomes their involvement.
