Reviews studies in which perceptual cue trading data have been compared with computational models and examines the perception of contrast between the voiceless fricative "s" and the voiceless affricate "ts." Nine subjects listened to a total of 6 tokens each of 193 stimuli and labeled each stimulus as containing either of the…

This study, the ninth in the series "Studies in the Phonology of Asian Languages," aims to analyze the phonological properties of the accentual system of Standard Colloquial Japanese on the basis of acoustic-phonetic data, especially data obtained through use of the sound spectrograph and pitch extractor. Chapters deal with functional distinctions…

This study is the sixth in the series "Studies in the Phonology of Asian Languages." A phonetic and phonemic analysis of the three complex nuclei of Vietnames (Hanoi dialect), spelled (1) ye-, -ie-, -ia, (2) -u'o'-, -u'a, and (3) -uo-, -ua, was carried out using the sound spectrograph. The relative domains of the target qualities of the…

At vowel onset following unvoiced consonants in /h-cvc/ utterances spoken by two talkers, Fo began high and fell about seven percent in the first five centiseconds. At closure of voiced oral obstruents, Fo suddenly dipped about ten percent, remained flat, suddenly rose about twenty five percent at opening of closure, and, after vowel onset,…

Recent studies of rising intonation contours in French, in particular the acoustical differences that serve to distinguish Yes/No questions from other rising intonations are reviewed. The preliminary results of a pilot study of rising intonations in French, in which average curves were obtained from spectrographic measurements of fundamental…

This study, the fifth in the series "Studies in the Phonology of Asian Languages," aims to describe those acoustic features involved in the distinction of Korean stop consonants, using the sound spectrograph and pitch extractor as research tools. The report specifically deals with voice onset time associated with weak and strong stops and the…

Automatic speech recognition is expected to be more successful when syntactically-related information is incorporated into early stages of recognition. Phonemic decisions, in particular, are expected to be more accurate and less ambiguous when contextual information is considered. A computer program detected about 90% of all boundaries between…

Local increases in fundamental frequency (Fo) and large integrals of energy in the syllabic nucleus are known to be among the best acoustical correlates of stress. Major syntactic constituents have been shown to have archetype rapid-rise-then-gradual-fall Fo contours, with the rise into the maximum Fo often associated with the first stressed…
