Kind Code:

Abstract:
[Problem] To minimize errors in identification caused by registered speech and provide stable and accurate identification of a speaker. [Solution] A speech recognition unit 102 extracts text data corresponding to a registered speech as extracted text data. The registered speech is speech that can be input by prompting a registered speaker to read aloud preliminarily established text data that is used for registration. A registered speech evaluation unit 103 calculates a score representing a similarity between the extracted text data and text data used for registration (a registered speech score) for each speaker. A dictionary registration unit 104 registers features for the registered speech with a speaker identification dictionary 108 used to register the features of a registered speech for each registered speaker in accordance with the evaluation results produced by the registered speech evaluation unit 103.
