Abstract
Emotional speech synthesis is expected to make the synthesized speech more expressive.In order to synthesis more natural emotional speech signals,this paper proposes a new emotional speech synthesis method combining Pitch Synchronous Overlap Add (PSOLA) and Discrete Cosine Transform (DCT).The research builds up emotional rules for happy,sad,neutral speech.Through analyzing the prosody parameters,it can modify the each syllable of neutral speech's fundamental frequency,energy and duration based on the emotional rules.The combination method adjusts pitch frequency for which marked pitch through DCT method,and then adjusts the pitch frequency to approach the target emotional fundamental frequency by the PSOLA algorithm.Experimental results show that the proposed method is more sensitive than the PSOLA algorithm.The subjective emotion recognition rate is higher,and the synthesized emotion speech quality is better.关键词
