An intelligent Thai computer terminal with the function of automatic and consecutive conversion from Roman script to Thai letters has been designed. It employs a Transliteration Method (TM) using a micro processor and a transliteration table which has been devised by any given Roman spelling. By using the proposed transliteration table, it is possible to reduce the number of keys on the keyboard by 46.7% compared with the method used for the ordinary IBM electronic Thai typewriter, here called the Direct Mapping Method (DMM). By estimating the number of key strokes from the frequency of occurrence of each Thai letter in the text of the Three Seals Law (Kotmai Tra Sam Duang) in Thailand, for which we are now developing a database, the number of key strokes required by the Transliteration Method are found to be greater than the number required by the Direct Mapping Method, but 10.1% smaller than by the method proposed by J.F.Hartmann and G.M.Henry(1983). For the display of Thai letters on the CRT, the dead key control for vowels, consonants, and tones are described.
