New ABC-MRT option provides an objective measure of speech intelligibility following the paradigm of the Modified Rhyme Test
Audio Precision announced today the addition of a new speech intelligibility measurement option for APx500 audio test software based upon the ABC-MRT speech processing algorithm. Measuring speech intelligibility is an important capability for engineers designing and validating a wide range of communication systems, products and components, especially those related to public safety (e.g., police, fire, emergency) where intelligibility is critically important.
Importance of Speech Intelligibility
The purpose of communication systems is to transmit information via speech. As such, the intelligibility—or comprehensibility—of the transmitted speech is of utmost importance. One of the more precise definitions of intelligibility is the proportion of speech items (words and/or speech sounds) uttered by a talker, and sent via a communication system, that can be recognized by the listener.
