In this paper, we propose an efficient method to establish Word Tone Dictionary(WTD). Vector qantization(VQ) is applied for compressing word tones for compressing word tones, and a phonetic-syntactic distance is adopted for searching the word tone dictionary. Because word tone is a sequence of syllable tones, VQ is used in encoding the syllable tones. As word tones in utterances are specified by their syntactic roles and phonetic features, we propose an adequate distance function to search the appropriate word tone in WTD. It is a combined distance function of syntactic distance and phonetic distance. We tested on a 100-utterance corpus. Preliminary experiments showed that the proposed method could lead to the natural pitch-controlled speech.
