Constructing a phonetic transcribed text corpus for Southern Thai dialect Speech Recognition

This paper presents the progress of the development of a Southern Thai dialect speech corpus to build automatic speech recognition. This is the recent Southern Thai dialect pronunciation dictionary containing more than 15,000 words, including words from a Southern Thai dialect dictionary, academic thesis papers, and online article resources. In this study, a hybrid technique was proposed to construct a phonetic of a Southern Thai dialect in building a Southern Thai Dialect Continuous Speech Recognition corpus. This system achieves 97.35% word accuracy in 6,500 sentences of the Southern Thai dialect. The complete resources are freely used available for the purpose of any research in order to encourage speech technology research in Southern Thai dialect.
