Abstract

A successfully implemented real-time Mandarin dictation machine which recognizes Mandarin speech with unlimited texts and very large vocabulary for the input of Chinese characters to computers is described. Isolated syllables including the tones are first recognized using specially trained hidden Markov models with special feature parameters. The exact characters are then identified from the syllables using a Markov Chinese language model. The real-time implementation is on an IBM PC/AT, connected to a set of special hardware boards on which ten TMS 320C25 chips operate in parallel. It takes only 0.45 s to dictate a character
