Research ArticleOpen accessPhrase in the titleEffects of Noises on Fundamental Frequency Extraction Using Cepstral Analysis for Thai DialectsSuphattharachai ChomphanProblem statement: The fundamental frequency (F0) of the human speech corresponds to the vibration frequency of the human vocal chords. To extract the F0 from a speech utterance, one approach is based on the Cepstral analysis. In Thai, there are four main dialects spoken by Thai people residing in four core region including central, north, northeast and south regions. Environmental … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 28 Jul 2012 · 6,908 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleSpeech Compression of Thai Dialects with Low-Bit-Rate Speech CodersSuphattharachai ChomphanProblem statement: In modern speech communication at low bit rate, speech coding deteriorates the characteristics of the coded speech significantly. Considering the dialects in Thai, the coding quality of four main dialects spoken by Thai people residing in four core region including central, north, northeast and south regions has not been studied. Approach: This study presents a comparative study of … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 14 Jul 2012 · 6,865 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEffects of Environmental Noises on Fundamental Frequency Contours of Thai DialectsSuphattharachai Chomphan, Chutarat ChompunthProblem statement: Fundamental Frequency (F0) is an important speech feature defining the human speech prosody. It is the resultant of the vibration of human’s vocal chords in speech production. In Thai, there are four main dialects spoken by Thai people residing in four core region including central, north, northeast and south regions.

Research ArticleOpen accessPhrase in the titleSpeech Compression for Noise-Corrupted Thai DialectsSuphattharachai ChomphanProblem statement: Dialects of Thai are quite different in the speaking styles. Environmental noises play an important role in corrupting the communication speech quality. Two factors affect the coded speech in the present speech communication. It is necessary to investigate how the two factors influence on the speech compression. Approach: In this study, the Multi-Pulse based Code Excited Linear Predictive … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 9 Jan 2012 · 7,238 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleFujisaki's Model of Fundamental Frequency Contours for Thai DialectsSuphattharachai ChomphanProblem statement: In general, there are a number of rural dialects in Thai. However, four dialects are mainly spoken by Thai people residing in four core region including central, north, northeast and south regions. Recognizing and synthesizing Thai speech with different dialects are consequently difficult. Approach: Prosody is an important factor that must be taken into account, since the prosody … …Journal of Computer Science, Vol. 6, Issue 11 · 19 Nov 2010 · 7,263 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleThai Dialects and Structural Modeling with NoisesSuphattharachai Chomphan, Numchok Budwong, Sirarot PreechatanapojFundamental Frequency (F0) conveys the prosodic information of the human speech. The modeling of the dialects’ F0 in a particular language is vital issue that should be taken into account. Four main dialects are spoken in different regions of Thailand including central, north, northeast and south regions.

Research ArticleOpen accessPhrase in the titleModeling of Fundamental Frequency Contours for Thai Dialects with Large Speech DatabaseSuphattharachai ChomphanIn four core regions of Thailand, there are four main dialects including central, north, northeast and south dialects. The prosody is significantly unique for each dialect. One important factor determining the prosody is the fundamental frequency. As a result, modeling of Fundamental frequency (F0) contour is very important for the natural speech processing. Even though there are many modeling techniques … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 20 Dec 2012 · 7,341 accessesView PDFCite
