Title:
SPEECH SYNTHESIS DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2005/109399
Kind Code:
A1
Abstract:
There is provided a speech synthesis device for creating a synthesized speech without significant lowering of voice quality. The speech synthesis device includes: a target speech piece information creation unit (102); a speech piece database (103); a speech piece selection unit (104); a voice quality specification unit (105); a voice quality conversion unit (106); a distortion judgment unit (108); and a target speech piece information correction unit (109). When a speech piece converted by the voice quality conversion unit (106) is judged to be distorted by the distortion judgment unit (108), the target speech piece information correction unit (109) converts the speech piece information created by the target speech piece information creation unit (102) into the speech piece information of the voice quality after the conversion and the speech piece selection unit (104) reselects a speech piece. Thus, without deteriorating the voice quality of the synthesized speech, it is possible to create a synthesized speech of the voice quality specified by the voice quality specification unit (105).
