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 effectiveness 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.
