Prosodic Aids to Speech Recognition: 7. Experiments on Detecting and Locating Phrase Boundaries

Abstract

Computer programs for detecting syntactic boundaries (BOUND3) and locating stressed syllables (STRESS) have been supplied to ARPA contractors and incorporated into speech recognition facilities. Experiments were conducted on various timing cues that correlate with phonological and syntactic phrase boundaries, showing that 91% of the phonological phrase boundaries that were perceived by listeners who heard spectrally inverted speech could be detected from lengthened vowels and sonorants in phrase-final positions. Also, 95% of these perceived boundaries were evidenced by long time intervals between syllables. The interstress interval also provided a good measure of rate of speech, that correlated with error rates in automatic phonetic classification schemes.
