MODEL ADAPTATION DEVICE, METHOD THEREOF, AND PROGRAM THEREOF

摘要

A model adaptation device approximates a model to a feature of an input voice so as to adjust the model to a speaker of the input voice.  The model adaption device includes: a text database containing a plurality of sentences having predetermined phonemes; a sentence list having a plurality of sentences describing the content of the input voice; an input means for inputting an input voice; a model adaptation means which outputs adaptation feature information for approximating the model to the input voice by using the input voice and the sentence list; a statistical amount database containing the adaptation feature information; a distance calculation means which outputs an acoustic distance value between the adaptation feature information and the model for each of the phonemes; a phoneme detection means which outputs as a detection result, a distance value which exceeds a threshold value among the distance values; and a label generation means which extracts from the text database, a sentence containing a phoneme associated with the detection result and outputs the sentence.
