摘要：本文概述了语音识别声学方面的一种策略，即利用韵律特征检测短语之间的边界，然后在每个组成部分中定位重音音节，并在重音音节中进行部分特征分析。实现了线性预测、波峰跟踪、基频和语音能量轮廓提取等功能。实现了一个程序，该程序可以检测基频轮廓中主要语法成分之间90%的所有边界。
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.
