On transitional algorithm of waveform concatenation in speech synthesis system

In the current waveform concatenation synthesis methods in Chinese speech synthesis,the effect between front syllable and behind syllable is not considered,which results in co-articulation inefficient synthesis in the joint of syllables.The co-articulation inefficient synthesis will decrease the naturalness of the synthesized speech.To solve this problem,an algorithm is proposed in this paper to perform transition of waveform concatenation by modifying parameters of the prosodic features in syllables,based on the research of prosodic features in Chinese speech.The experiments show the proposed method to be validity.The naturalness of speech synthesis is higher and lower demand on the corpus size.
