Abstract
This paper proposed a emotional speech synthesis system based on pitch synchronous overlap-add ( PSOLA) . Pro-sodic parameters could be changed in this system freely. First, analyzing pre-recorded emotional speech samples' it concluded some acoustic features associated closely with happiness, angry, surprise and sadness. Then it used TD(time domain)-PSOLA algorithm to change the speech prosodic parameters of neutral speeches. Especially, it proposed a approach to change the FO contour. Experiments demonstrates that the system is effective, which helps to express the facial speech animation more vividly.关键词
