Abstract:

A strategy is outlined for acoustic aspects of speech recognition, whereby prosodic features are used to detect boundaries between phrases, then stressed syllables are located within each constituent, and a partial distinctive features analysis is done within stressed syllables. Facilities were implemented for linear prediction, formant tracking, and extraction of fundamental frequency and speech energy contours. A program was implemented which detects 90 of all boundaries between major syntactic constituents from fall-rise valleys in fundamental frequency contours.
