Since Thai language lacks word/phrase/sentence boundaries, document summarization in Thai needs investigations in unit segmentation, unit selection, redundancy removal and evaluation dataset construction. In this work, we have proposed Thai Elementary Discourse Unit (TEDU) and a three-stage method of Thai multidocument summarization, i.e., unit segmentation, unit-graph formulation, and unit sel...

A Thai written text is a string of symbols without explicit word boundary markup. A method for a development of a segmentation tool from a corpus of already segmented text is described. The methodology is based on the technology of competing patterns, evolved from algorithm for English hyphenation. A new UNICODE pattern generation program, OPATGEN, is used for the learning phase. We have shown ...

The oldest Thai script found in the history dated over 700 years ago, in Sukhothai age. Over years, Thai script has been gradually changed. The contemporary Thai alphabet comprises 44 consonants, 32 vowels, 4 tone marks, 2 diacritics, and 10 decimal digits. These cover only the minimal set of symbols to write Thai words. There are additional 3 symbols particularly used for writing Pali and Sans...

Previous literature describes Thai children as unusually polite, deferent, and behaviorally restrained. Yet, in a recent study employing teacher reports, Thai children were reported to show many more behavior problems than American children. Such a finding may reflect culture-linked differences in the perspective of Thai versus American teachers. To explore this possibility, we used trained obs...

Thai traditional medicine is one of the most valuable heritages handed down from Thai ancestors. In spite of increasing popularity of Western modern medicine, Thai traditional medicine is still widely used in taking care of health in daily life especially among the rural Thais. For the past decade, the government and private organizations have worked in collaboration to restore the values and p...

This study examined Australian English speakers’ and Thai-English bilingual speakers’ ability to perceive word-final stops in English and Thai. Thai bilinguals lived in Sydney, Australia, for 5.5 years on average (range = 0.2 – 30.3). In Experiment 1 (categorial discrimination test), Thai bilinguals were able to discriminate stop contrasts differing in place of articulation in their two languag...

* Faculty of Information Technology, Rangsit University. Abstract With the rapidly increasing number of Thai text documents available in digital media and websites, it is important to find an efficient text indexing technique to facilitate search and retrieval. An efficient index would speed up the response time and improve the accessibility of the documents. Up to now, not much research in Tha...

Thai speech synthesis by rule has been developed. In order to synthesize F0 contours of Thai tones, the generative model of F0 contours (Fujisaki's model) for tonal languages is applied. Along with our method, the pitch contours of Thai polysyllabic words were analyzed. Rules are derived and applied to synthesize Thai polysyllabic tone sequences. We performed listening tests to evaluate intelli...

OBJECTIVE To evaluate the reliability and validity of the Thai version of the neck disability index (NDI) in neck pain patients. MATERIAL AND METHOD The NDI was translated into Thai. The translation strategy used international standards. Forty-six Thai patients with neck pain were included in the present study. Thai version NDI, short form-36 (SF-36) and visual analogue scale (VAS) were compl...

This paper presents a characteristic study of Thai segmental duration and adapts the analysis results to construct a Thai phone duration model for Thai speech synthesis. The study uses Hayashi's categorized linear regression model to analyze the effects of various factors including current phonemes themselves, surrounding phonemes, phone positions in word, phone positions in phrase, part-of-spe...
