摘要

This paper presents a duration-embedded Bi-HMM framework for expressive voice conversion. First, Ward's minimum variance clustering method is used to cluster all the conversion units (sub-syllables) in order to reduce the number of conversion models as well as the size of the required training database. The duration-embedded Bi-HMM trained with the EM algorithm is built for each sub-syllable class to convert the neutral speech into emotional speech considering the duration information. Finally, the prosodic cues are included in the modification of the spectrum-converted speech. The STRAIGHT algorithm is adopted for high-quality speech analysis and synthesis. Target emotions including happiness, sadness and anger are used. Objective and perceptual evaluations were conducted to compare the performance of the proposed approach with previous methods. The results show that the proposed method exhibits encouraging potential in expressive voice conversion.
