Intelligibility and Acceptability Testing for Speech Technology

Abstract

The evaluation of speech intelligibility and acceptability is an important aspect of the use, development, and selection of voice communication devices-telephone systems, digital voice systems, speech synthesis by rule, speech in noise, and the effects of noise stripping. Standard test procedures can provide highly reliable measures of speech intelligibility, and subjective acceptability tests can be used to evaluate voice quality. These tests are often highly correlated with other measures of communication performance and can be used to predict performance in many situations. However, when the speech signal is severely degraded or highly processed. a more complete evaluation of speech quality is needed-one that takes into account the many different sources of information that contribute to how we understand speech.
