This paper describes a technique for reproducing local prosodic variability which appears in expressive speech including various speaking styles. Synthetic speech generated using only linguistic contexts in HMM-based speech synthesis tends to have smaller prosody variation compared with the original speech. To add more variation in synthetic speech, we define novel phrase-level prosodic contexts from the residual information of prosodic features between original and synthetic speech for training data. Specifically, we create the prosodic contexts of F0, duration, and power feature by using average difference between original and synthetic speech in each phrase. We evaluate the potential of the proposed technique under a condition where the appropriate prosodic contexts of test sentences are known in synthesis phase. We also examine whether users can intuitively modify the pitch by adjusting proposed prosodic contexts. |
