Speech synthesizer, speech synthesizing method, and computer program
First Claim
1. A speech synthesizer for creating speech for reading a sentence using previously recorded speech comprising:
- a speech storage section for storing the speech of each of a plurality of speakers;
a feature information storage section for storing speaker feature information, which shows a feature as to the utterance of each of the speakers specified from speech;
a reading feature designation section for designating reading feature information showing a feature as to an utterance when a sentence is read;
a check section for deriving the degree of similarity as to the utterance of the speaker corresponding to the feature designated by the reading feature designation section based on the reading feature information designated by the reading feature designation section and on the speaker feature information stored in the feature information storage section; and
a speech synthesizing section for obtaining the speech of a speaker having a feature similar to the feature designated by the reading feature designation section from the speech storage section based on the degree of similarity derived by the check section and creating a synthesized speech for reading the sentence based on the speech.

Abstract
A speech synthesizer includes a speech storage section for storing the speech of each of a plurality of speakers, a feature information storage section for storing speaker feature information which shows a feature as to the utterance of each of the speakers specified from speech, a reading feature designation section for designating reading feature information, a check section for deriving the degree of similarity of a feature as to the utterance of the speaker designated by the reading feature designation section based on the designated reading feature information and on the speaker feature information, and a speech synthesizing section for obtaining the speech of a speaker having a feature similar to the feature designated by the reading feature designation section from the speech storage section based on the derived degree of similarity and creating synthesized speech for reading a sentence based on the speech.

11. A computer program for causing a speech synthesizer, which creates speech for reading a sentence using previously recorded speech, to execute:
-
a reading feature designation processing for designating reading feature information showing a feature as to an utterance when a sentence is read;
a check processing for deriving the degrees of similarity of features as to the utterances of speakers to the feature designated by the reading feature designation processing based on the speaker feature information in a feature information storage section in which speaker feature information, which shows a feature as to the utterance of each of the speakers specified from speech, is stored and on the reading feature information designated by the reading feature designation processing; and
a speech synthesizing processing for obtaining the speech of a speaker having a feature similar to the feature designated by the reading feature designation processing from a speech storage section in which the speech of each of a plurality of speakers are stored based on the degrees of similarity derived by the check processing and creating synthesized speech for reading the sentence based on the speech.

12. A speech synthesizing method of creating speech for reading a sentence using previously recorded speech comprising:
-
a speech storage step of storing the speech of each of a plurality of speakers in storage means;
a feature information storage step of storing speaker feature information showing a feature as to the utterance of each of the speakers specified from the speech in storage means;
a reading feature designation step of designating reading feature information showing a feature as to an utterance when a sentence is read;
a check step of deriving degrees of similarity of features as to the utterances of the speakers to the feature designated by the reading feature designation step based on the reading feature information designated by the reading feature designation step and on the speaker feature information stored in the storage means; and
a speech synthesizing step of obtaining the speech of a speaker having a feature similar to the feature designated by the reading feature designation step from the storage means based on the degrees of similarity derived by the check step and creating synthesized speech for reading the sentence based on the speech.
