Golden Mandarin (II) is an intelligent single-chip based real-time Mandarin dictation machine for the Chinese language with a very large vocabulary for the input of unlimited Chinese texts into computers using voice. This dictation machine can be installed on any personal computer, in which only a single chip Motorola DSP 96002D is used, with a preliminary character correct rate around 95% at a speed of 0.6 sec per character. Various adaptation/learning functions have been developed for this machine, including fast adaptation to new speakers, on-line learning the voice characteristics, task domains, word pattern and noise environments of the users, so the machine can be easily personalized for each user. These adaptation/learning functions are the major subjects of the paper
