• The HMM-based Text-to-Speech System has attracted great interest due to its compact and flexible modeling of spectral, F0 and duration parameters. The synthesized speech is highly dependent on the context model. However, the complex F0 variations make it rather difficult to define the tone type of Mandarin continuous speech. Then the F0 and duration trajectories, generated by HMM-based speech synthesis are often excessively smoothed and lack of prosodic variance. Tone nucleus of a syllable is assumed to be the target F0 of the associated lexical tone, and usually conforms more likely to the standard tone pattern. In this paper, by modeling F0 variations at different levels ranging from segmental factors to tone co-articulations, and apply the tone nucleus model to HMM-based Mandarin speech synthesis.
