| Research Abstract |
A scheme for communicative prosody generation was proposed to synthesize speech needed for conversational purposes. Using the correlation between communicative prosody and impression attributes of lexicons constituting output, the proposed scheme enables prosody control for conversational speech output. Perceptual experiments showed the superiority of the speech synthesized with the proposed communicative prosody to the conventional one with reading style prosody. Further application to Chinese and English speech synthesis and the reverse technology of impression extraction from speech clarified the usefulness of the proposed approach.
