<P>PROBLEM TO BE SOLVED: To provide a speech synthesizer capable of reducing time required for generating synthesized speech even when the synthesize speech is generated by using any of plural synthesis conditions different from one another for a predetermined original. <P>SOLUTION: A speech synthesizer 1 includes: a matching determination unit 10 for determining whether a set of input text information or input phonetic information and an input synthesis condition matches any of sets of at least one piece of registered text information or registered phonetic information and a registered synthesis condition; and an automatic update unit 17 for, when the set of the input text information and the like does not match any of the sets of the registered text information and the like, generating a set of derivative text information and derivative synthesis condition by correcting the input text information or the input synthesis condition, and making a storage unit 3 store a set of a set of the derivative text information and the derivative synthesis condition and derivative intermediate information generated during generation of a synthesized speech signal by a speech synthesis unit 11 based on the derivative text information and the derivative synthesis condition, as a set of a set of the registered text information and the registered synthesis condition and registered intermediate information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
