Abstract:

A speaker recognizing device, a speaker recognizing method, a speaker recognition processing program, etc. for more improving the performance of speaker recognition are provided. A speech uttered by a speaker is inputted. An acoustic parameter indicating a feature of the inputted speech is extracted. The extracted acoustic parameter is compared and collated with reference acoustic data stored in a speech feature DB (3). If the collation result shows incorrectness, the speaker inputs personal feature information representing a speaker feature other than that of speech. The inputted personal feature information is compared and collated with reference personal feature information stored in a speech feature DB (6). If the collation results shows correctness, the reference acoustic data stored in the speech feature DB (3) corresponding to the extracted acoustic parameter is updated by using the acoustic parameter.
