This paper presents a prototype prosodic-segment-based Mandarin dictation machine for the Chinese language with very large vocabulary. It accepts utterances continuous within a prosodic segment which is composed of one or a few word(s). It also possesses various on-line learning capabilities for fast adaptation to a new user in acoustic, lexical and linguistic levels. The overall system is implemented on an IBM/PC with an additional DSP card including a Motorola DSP 96002 chip. The word accuracy can achieve nearly 90% for a new user after he produces about 10 minutes of speech to train the system, and the accuracy can be further improved with the on-line learning functions.
