Abstract
A speech synthesis method includes selecting a segment, determining whether to conduct prosodic modification on the selected segment, calculating a target value of prosodic modification of a segment on which prosodic modification has been determined to be conducted based on a result of the determination, conducting prosodic modification such that a prosody of the segment on which prosodic modification has been determined to be conducted takes the target value of prosodic modification, and concatenating the segment on which prosodic modification has been conducted or a segment on which prosodic modification has been determined not to be conducted as a result of the determination.
Claims10
A speech synthesis method comprising:
- selecting a segment;
- determining whether to conduct prosodic modification on the selected segment;
- calculating a target value of prosodic modification of the selected segment when it is determined that prosodic modification is to be conducted on the selected segment;
- conducting prosodic modification such that a prosody of the selected segment on which prosodic modification has been determined to be conducted takes the calculated target value of prosodic modification;
- and
- concatenating the selected segment on which prosodic modification has been conducted or the selected segment on which prosodic modification has been determined not to be conducted.
A speech synthesis apparatus comprising:
- a selecting unit configured to select a segment;
- a determining unit configured to determine whether to conduct prosodic modification on the selected segment;
- a calculating unit configured to calculate a target value of prosodic modification of a segment on which prosodic modification has been determined to be conducted based on a determination result by the determining unit;
- a modification unit configured to conduct prosodic modification such that a prosody of the segment on which prosodic modification has been determined to be conducted takes the calculated target value of prosodic modification;
- and
- a segment concatenating unit configured to concatenate the segment on which prosodic modification has been conducted or a segment on which prosodic modification has been determined not to be conducted based on a determination result by the determining unit.
