A Novel Algorithm of Co-articulation Emotional Chinese Speech Synthesis Based on TD-PSOLA

摘要：

Speech synthesis technologies are the foundation of phonetic human-machine interaction.The tendency in the future development of speech synthesis technologies is how to further improve expressive ability of the machine synthesized speech and imitate the speakers emotive state,which is still a difficult problem in the research field.In this paper,TD-PSOLA,based on decomposing the spectrum of speech signal,was used to deal with the co-articulation phenomenon in the syllable junction of speech synthesis,and those emotional parameters of speech synthesis were analyzed.CECTD-PSOLA,which is an algorithm of Co-articulation Emotional Chinese Speech Synthesis based on decomposing the spectrum of speech signal,was proposed in this paper.The co-articulation phenomenon between syllables,and emotional factors contained in speech was considered in the CECTD-PSOLA.The experimental results show that the algorithm could better increase naturalness and emotion of Chinese speech synthesis.
