Abstract

This paper describes a module for acoustic/phonetic transcription in a continuous speech understanding system. This module segments input utterances into sequences of phone classes which belong to one of six broad phonetic categories. In a higher system level such segment sequences are used to hypothesize possible word candidates from a lexicon.

This module is hierarchically implemented in two stages: a polynomial classifier for a frame-by-frame classification of phone classes followed by a segmentation stage using Hidden Markov Models (HMM) of phone class segments.
