Speech recognition based on the syllable segment is discussed in the paper. Special emphasis is put on the methods for estimation of syllable boundaries and methods of comparison of syllable segments by DTW algorithms. The method of characteristic function for estimating of the boundaries between syllable segments is introduced. This method is also utilized in the proposed DTW algorithm for syl...

In this paper, we will describe a Korean transliterated foreign word extraction algorithm. In the proposed method, we reformulate the foreign word extraction problem as a syllable-tagging problem such that each syllable is tagged with a foreign syllable tag or a pure Korean syllable tag. Syllable sequences of Korean strings are modelled by Hidden Markov Model whose state represents a character ...

This paper presents another approach of Thai word segmentation, which is composed of two processes : syllable segmentation and syllable merging. Syllable segmentation is done on the basis of trigram statistics. Syllable merging is done on the basis of collocation between syllables. We argue that many of word segmentation ambiguities can be resolved at the level of syllable segmentation. Since a...

In our previous research, we demonstrated the validity of segmental unit input hidden Markov model (HMM), which regards successive four frame MEL-cepstrum coefficients as a feature vector. The vector is reduced to lower dimensions using the KL transform. However, the model considers only the correlation between frames in a short section, but not the correlation between the frames over a long se...

Mandarin is a syllable-timed language whose syllable structure is quite simple [1]. In spontaneous Mandarin, because of rapid speech rate the structure of syllable may be changed, phonemes may be reduced and syllable boundaries as well as lexical tones may be merged. This fact has long been noticed, but no quantified empirical data were actually presented in the literature until now. This paper...

This paper describes the analysis results on the control factors of Thai syllable duration, and a statistical control model using linear regression technique. The analyses have been carried out both at a syllable level and at a phrase level. In a syllable level duration control, the effects of five Thai tones and syllable structures are investigated. To analyze syllable structure effects statis...
