In this paper, a two-stage recognition scheme, phonetic recognition followed by prosodic recognition, is established. In the phonetic recognition process, 21 INITIAL and 37 FINAL context-independent HMM's are used to construct the phonetic recognizer. In the prosodic recognizer, 175 context-dependent prosodic HMM's are used to model the complicated tone behavior for all possible tone concatenations. Five anti-prosodic HMM's, each corresponding to one lexical tone, are constructed to enhance the discriminability among prosodic HMM's. This system was evaluated in a speaker-dependent mode on a vocabulary size of thirty thousand words. The experimental results show that the recognition rate was improved from 80.3% to 86.7% using the prosodic information.
