ABSTRACT: The synthesis of emotional speech has wide applications
in the field of human-computer interaction, medicine, industry and so on. In
this work, an emotional speech synthesis system is proposed based on prosodic
features modification and Time Domain Pitch Synchronous OverLap Add (TD-PSOLA)
waveform concatenative algorithm. The system produces synthesized speech with
four types of emotion: angry, happy, sad and bored. The experiment results show
that the proposed emotional speech synthesis system achieves a good performance.
The produced utterances present clear emotional expression. The
subjective test reaches high classification accuracy for different types of
synthesized emotional speech utterances.
