Research ArticleOpen accessPhrase in the titleAnalytical Study of High Pitch Delay Resolution Technique for Tonal Speech CodingSuphattharachai Chomphan, Chutarat ChompunthProblem statement: In tonal-language speech, since tone plays important role not only on the naturalness and also the intelligibility of the speech, it must be treated appropriately in a speech coder algorithm. Approach: This study proposes an analytical study of the technique of High Pitch Delay Resolutions (HPDR) applied to the adaptive codebook of core coder of Multi-Pulse based Code … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 23 Jan 2012 · 6,913 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleTonal Language Speech Compression Based on a Bitrate Scalable Multi-Pulse Based Code Excited Linear Prediction CoderSuphattharachai ChomphanProblem statement: Speech compression is an important issue in the modern digital speech communication. The functionality of bitrates scalability also plays significant role, since the capacity of communication system varies all the time. When considering tonal speech, such as Thai, tone plays important role on the naturalness and the intelligibility of the speech, it must be treated appropriately. Therefore these … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,810 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleHigh Pitch Delay Resolution Technique for Tonal Language Speech Coding Based on Multi-Pulse Based Code Excited Linear Prediction AlgorithmSuphattharachai ChomphanProblem statement: In spontaneous speech communication, speech coding is an important process that should be taken into account, since the quality of coded speech depends on the efficiency of the speech coding algorithm. As for tonal language which tone plays important role not only on the naturalness and also the intelligibility of the speech, tone must be treated appropriately. Approach: … …Journal of Computer Science, Vol. 7, Issue 1 · 14 Jan 2011 · 6,729 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleMulti-Pulse Based Code Excited Linear Predictive Speech Coder with Fine Granularity Scalability for Tonal LanguageSuphattharachai ChomphanProblem statement: The flexible bit-rate speech coder plays an important role in the modern speech communication. The MP-CELP speech coder which is a candidate of the MPEG4 natural speech coder supports a flexible and wide bit-rate range. However, a fine scalability had not been included. To support finer scalability of the coding rate, it had been studied in this study. … …Journal of Computer Science, Vol. 6, Issue 11 · 24 Nov 2010 · 7,191 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPerformance Evaluation of Multi-Pulse Based Code Excited Linear Predictive Speech Coder with Bitrate Scalable Tool over Additive White Gaussian Noise and Rayleigh Fading ChannelsSuphattharachai ChomphanProblem statement: In the modern speech communication technology, the speech coding with bitrate scalability was needed. However, various types of noises in the communication channels cause damages in the transmitted information especially speech data. Tonal-language speech was also affected by this situation. Approach: Based on the high pitch delay resolution technique, the MPCELP speech coding was proposed over the environment … …Journal of Computer Science, Vol. 6, Issue 12 · 6 Nov 2010 · 7,085 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStructural Modeling of Fundamental Frequency contour for Thai TonesSuphattharachai ChomphanProblem statement: In Thai, tone is an essential feature of a prosodic syllable to identify the meanings of that syllable or that part of word. To generate the tonal speech with natural prosody, it is needed to manage the fundamental frequency (F0) of the speech appropriately. A successful approach of structural modeling from Mandarin Chinese has been adapted to model … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 7,122 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalytical Study of Fujisaki’s Model of Fundamental Frequency Contour for Thai TonesSuphattharachai Chomphan, Chutarat ChompunthProblem statement: Tone of a tonal language is an important feature of a prosodic syllable to identify the meanings of that syllable or that part of word. Ii is very crucial to model the feature related to tone of speech to achieve the most naturalness in speech communication. Approach: The study presents an approach to analyze the model parameters of … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 16 Aug 2012 · 6,991 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImprovement of Tone Intelligibility for Average-Voice-Based Thai Speech SynthesisSuphattharachai Chomphan, Chutarat ChompunthProblem statement: Tone intelligibility in speech synthesis is an important attribute that should be taken into account. The tone correctness of the synthetic speech is degraded considerably in the average-voice-based HMM-based Thai speech synthesis. The tying mechanism in the decision tree based context clustering without appropriate criterion causes unexpected tone neutralization. Incorporation of the phrase intonation to the context clustering … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 24 Jan 2012 · 6,969 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThai Expressive Speech Processing Technology: A ReviewSuphattharachai ChomphanProblem statement: The studies on Thai expressive speech or emotional speech have been conducted for years. Most of them are expected to analysis the characteristics of Thai expressive speech. However, the conclusive reviews on these studies have not been conducted for further study on the speech technology or application of Thai expressive speech. Approach: The review of research on Thai … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 12 Jan 2012 · 6,733 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModeling of Fundamental Frequency Contour of Thai Expressive Speech using Fujisaki's Model and Structural ModelSuphattharachai ChomphanProblem statement: In spontaneous speech communication, prosody is an important factor that must be taken into account, since the prosody effects on not only the naturalness but also the intelligibility of speech. Focusing on synthesis of Thai expressive speech, a number of systems has been developed for years. However, the expressive speech with various speaking styles has not been accomplished. … …Journal of Computer Science, Vol. 7, Issue 8 · 9 Aug 2011 · 6,975 accessesView PDF Cite
