Speech Intelligibility STIPA

Spoken announcements in public areas like classrooms, conference halls, shopping malls, stadiums, train stations, airports, concert halls, or similar locations should be well understandable to the audience. Particularly, it is critical to clearly inform persons in danger about escape information and directions in case of an emergency. It is therefore essential to verify the speech intelligibility in these places by using a reproducible and accurate method.

Speech Transmission Index STI is the most acknowledged standardized parameter for assessing the intelligibility of a spoken message.
