Description / Abstract:

This American National Standard specifies an experimental method for evaluation of the intelligibility of synthetic speech, in English, generated by text-to-speech (TTS) synthesis systems. It is intended to be used by developers of applications that incorporate TTS technology, such as e-mail and SMS readers, talking kiosks, e-learning systems, navigation systems, automated messaging services, screen readers for people who are blind, and assistive devices for people who have difficulty speaking.

Although this Standard is targeted toward English, many of the recommendations and requirements concerning experimental design, listener selection and training, test materials and procedures, and measurement and analysis of results are sufficiently general to be valid for evaluating the intelligibility of synthetic speech in languages other than English.

This Standard describes methodology that is applicable both for comparisons of different TTS systems, and for comparisons of different versions of the same TTS system.
