- CHULALONGKORN University's Linguistics Research Unit has completed the
- first Thai text-to-speech system prototype for PCs -- a system that
- synthesizes Thai speech output using text input. The project will be
- further developed into a speech recognition system.
-
- Supervised by Dr Sudaporn Luksaneeyanawin, chief of the Linguistics
- Research Unit of the Faculty of Arts of Chulalongkorn University, the
- Thai text-to-speech system was funded by the National Electronics
- Computer and Technology Centre (NECTEC) with a budget of some
- 1,030,000 baht.
-
- The project was started in 1989 by a research team of some 10 people.
-
- According to Dr Sudaporn, the Thai text-to-speech system was part of
- an artificial intelligence project aimed at creating artificial
- language skills where computers were made to speak or narrate Thai
- similar to a person for use as a computer aided instruction tool to
- assist students with spelling and pronunciation.
-
- She said that the system was developed on a personal computer using
- the C programming language and Foxbase package. She noted that they
- decided to develop it on the PC platform because in Thailand this
- package could then be further developed by local users who were
- experienced with PCs. It would not have been practical to do it on a
- workstation or some other platform, she added.
-
- Development of the Thai text-to-speech system was divided into three
- modules: a Thai text and character processing module, a sound unit
- analysis module, and a speech sound synthesizing module.
-
- She explained that the Thai text and character processing module
- converted strings of Thai letters that were enterred into strings of
- Thai phonetic words, while the under line module was
- basically two dictionaries: a phonetic word dictionary and a sound
- dictionary. And the sound synthesizing module mixed the proper sound
- unofficially.
-
- Dr Sudaporn said that Thai characters were much different from other
- languages because of the nature of Thai written language which had no
- spaces between words, nor full stops in sentences, and there was ambig
- uity in certain words or sentences which ha
-
- d different pronounciations due to vowels and consonants.
-
- She added that the most painstaking work for the team was to process
- the Thai characters into sound units which was done by consulting a
- Thai encyclopedia. This task took about a year and a half year to
- complete, she said.
-
- Although this was just a prototype, this results of this basic
- research, she added, would be a tremendous source of information and
- knowledge to the Linguistics Research Unit for further research in
- speech technology and natural language processing.
-
- The Thai text-to-speech system now has two dictionaries of 30,000 Thai
- words and some add-in technical terms and specific words in Thai.
-
- Dr Sudaporn noted that the system could be applied for teaching
- pronunciation and spelling to the blind, kindergaten students and
- tourists. The next project was to further develop the system into a
- speech recognition system, she said.
