Perception-based automatic approximation of F0 contours in Cantonese speech

In our previous studies, it was found that F0 variations in Cantonese speech can be adequately represented by linear approximations of the observed F0 contours, in the sense that comparable perception with natural speech can be attained. The approximated contours were determined manually. In this study, a framework is developed for automatic approximation of F0 contours. Based on the knowledge ...

Perception of intonation in Cantonese

This study investigated the perception of Cantonese intonation by an exemplar-theoretic model, without using F0 normalization. Exemplar Theory (Johnson, 1997) claims that listeners store experienced utterances (i.e., exemplars) in rich phonetic detail, so that when a new utterance is heard, it is classified by comparing its auditory similarity to all exemplars stored in memory, without using sp...

Perception of intonation in Cantonese

This study investigated the significance of different intonation markers in intonation perception, and the effect of lexical tone on the perception of intonation. Six tonal contrasts at the final position were presented to twelve listeners in three presentation conditions: complete sentence, carrier-only and final-syllable-only. Results showed similar perceptual accuracy in both complete senten...

Vowel Length Perception in Cantonese

This paper reports the acoustic experiment and perception test on a pair of Cantonese long and short vowels /a/ and /ɐ/ in the diphthong context. The acoustic data show that [aːi] and [ɐi] have similar targets of vowel nucleus and coda, parallel transition glide, and comparable total duration. They are different in their durational structure: [aːi] has a long steady phrase of vowel nucleus whi...
