Speech synthesizing apparatus, method, and program
First Claim
1. A speech synthesizing apparatus comprising:
- a storage unit that stores speech segments; and
a segment selection unit that selects a segment suited to a target segment environment from among a plurality of candidate segments selected from the storage unit, whereinthe segment selection unit performs control to exclude, from the candidate segment which is a candidate of the selection, a segment having a prosody change amount less than a selection criterion that is determined based on a prosody change amount of the candidate segments.

Abstract
Disclosed is a speech synthesizing apparatus including a segment selection unit that selects a segment suited to a target segment environment from candidate segments, includes a prosody change amount calculation unit that calculates prosody change amount of each candidate segment based on prosody information of candidate segments and the target segment environment, a selection criterion calculation unit that calculates a selection criterion based on the prosody change amount, a candidate selection unit that narrows down selection candidates based on the prosody change amount and the selection criterion, and an optimum segment search unit than searches for an optimum segment from among the narrowed-down candidate segments.

11. A speech synthesizing method comprising:
-
providing a non-transitory storage unit, coupled to a processor, that stores speech segments; providing a segment selection unit; selecting a plurality of candidate segments for a target segment environment from the storage unit that stores speech segments; and selecting with the segment selection unit a segment suited to the target segment environment from among a plurality of candidate segments, wherein the step of selecting the segment comprises performing control to exclude, from the candidate segment which is a candidate of the selection, a segment that has a prosody change amount less than a selection criterion determined based on a prosody change amount of the candidate segments. - View Dependent Claims (12)

13. A non-transitory computer-readable recording medium storing a program that causes a computer which constitutes a speech synthesizing apparatus, to execute:
-
a processing of selecting a plurality of candidate segments for a target segment environment from a storage unit that stores speech segments; and a processing of selecting a segment suited to a target segment environment from among a plurality of candidate segments, wherein the processing of selecting the segment comprises;
performing control excluding, from the candidate segment which is a candidate of the selection, a segment that has a prosody change amount less than a selection criterion that is determined based on a prosody change amount of candidate segments. - View Dependent Claims (14)
