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…

Lea, Wayne A. – 1972
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,…

Howie, John M. – 1973
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…

Lea, Wayne A.; And Others – 1972
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…

Lea, Wayne A. – 1973
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…

Lea, Wayne A. – 1973
Acoustical correlates of stress can only be evaluated in comparison with some "standard" specifying which syllables are actually stressed. The Standard should be consistent from time to time, and largely independent of talker and listener idiosyncrasies. Three phonetically-trained subjects listened to repeatedly spoken texts and spontaneous…
