Abstract
A speech synthesizing apparatus extracts small speech segments from a speech waveform as a prosody control target and adds inhibition information for inhibiting a predetermined prosody change process to a selected small speech segment in executing prosody control. Prosody control is performed by performing a predetermined prosody change process by using small speech segments of the extracted small speech segments other than small speech segments to which inhibition information is added. This makes it possible to prevent a deterioration in synthesized speech due to waveform editing operation.
Claims22
A speech synthesizing method comprising:
- the extraction step of extracting a plurality of small speech segments from a speech waveform;
- the prosody control step of processing the plurality of small speech segments to control prosody of the speech waveform while limiting processing for a selected small speech segment of the plurality of small speech segments;
- and
- the synthesizing step of obtaining synthesized speech by using the speech waveform for which prosody control is performed in the prosody control step.
A speech synthesizing apparatus comprising:
- extraction means for extracting a plurality of small speech segments from a speech waveform;
- prosody control means for processing the plurality of small speech segments to control prosody of the speech waveform while limiting processing for a selected small speech segment of the plurality of small speech segments;
- and
- synthesizing means for obtaining synthesized speech by using the speech waveform for which prosody control is performed by said prosody control means.
