Abstract：The tone evaluation of Chinese continuous speech is a key aspect in Mandarin Chinese pronunciation test. Taking advantage of the close correlation between the prosody framework and the modified tonal curve, this paper presents a Multi-Space Distribution Hidden Markov Model (MSD-HMM) built on the prosodic word for the tone evaluation. The experimental results show that the proposed Mandarin Chinese Pronunciation Evaluation System improves from 82.0% to 84.6% in the performance of tonal syllable error rate for the standard Chinese continuous speech. And for the non-standard Chinese Mandarin speech, the correlation between computer score and expert score achieves over 3.0% absolute improvements compared with that of the baseline system without tone pronunciation test.
