This research provided the first analysis of Thai phonemes using a large real-speech corpus,
not just a small set of sample utterances.
There is still a lack of sufficient research on prosody analysis for
Thai, however data collection is not a trivial task, and thus
research on prosody modeling has been substantially
delayed. Since 2000, research on basic linguistic features
has decreased and the engineering of high-level speech
applications such as speech recognition and synthesis has
taken priority.
