A robust tone recognition method of Chinese based on sub-syllabic F0 contours
نویسندگان
چکیده
This paper proposes a scheme of using F0 contours of vowel nuclei to discriminate Chinese lexical tones. The authors suggest that the F0 contour fragment of a vowel nucleus of a syllable contributes most to tone perception of the syllable. To correlate the F0 contour with the phonemic components of a syllable, a tone-based syllabic structure is also proposed. Tone recognition experiments on a speaker independent dissyllable words task proved the e ectiveness of the proposed method. Better performance over approaches observing full syllabic F0 contours indicates that the proposed method is a more robust tone recognition method.

Research on dynamic characters of Chinese pitch contours
Chinese is a tone language. For a tone, the characters of its F0 pitch contours will be quite different in the condition of continuant speaking from the isolated speaking. The present researches about the Chinese tone are still centralized on the isolated speaking one, and about tone in fluent speech, there are some statements about the phenomenon of the two-word, threeword, four-word co-readin...
متن کاملAnalysis of F0 contours of Cantonese utterances based on the command-response model
As a major Chinese dialect, Cantonese is well known for its complex tone system. This paper applies the commandresponse model to represent the F0 contours of Cantonese speech. Analysis-by-Synthesis is conducted on both utterances of carrier sentences and utterances with less constrained structures, from which a set of appropriate tone command patterns is derived. By intrinsically incorporating ...
متن کاملQuantitative analysis of F0 contours of emotional speech of Mandarin
For emotional speech synthesis, a quantitative model giving a parametric representation of F0 contours is needed. Purpose: investigate quantitatively F0 characteristics of Mandarin speech in four basic emotions (anger, fear, joy, and sadness) and in neutral reading. Two approaches are compared: surface features analysis from time-normalized F0 contours analysis-by-synthesis of time-intact F0 co...

This paper presents our tone nucleus based framework to model the complex variations in sentential F0 contours to build robust tonal acoustic models. By focusing on tone nuclei, the approach can get rid of the influence of aritculatory transition loci on tonal modeling. Anchoringbased Tone nucleus normalization improves the discriminability among the tones. Hypoand Hyperintonation model is to a...

As one of the major Chinese dialects, Shanghainese is well known for its complex tone sandhi system. This paper applies the command-response model to represent F0 contours of Shanghainese speech. Analysis-by-Synthesis is conducted both on carrier sentences with monosyllabic target words and on isolated polysyllabic words, from which a set of appropriate tone command patterns is derived for word...
