ACOUSTIC MODEL DEVELOPMENT SYSTEM AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an apparatus with which an acoustic model of a target language is quickly developed by using a language resource of a source language which is different from the target language. SOLUTION: A model 50 for developing the acoustic model (AM) of a first language includes: a voice data of a second language; a mapping table 66 for mapping a phoneme label of the second language to the phoneme label of the first language; a replacing module 62 for replacing the phoneme label of the second language to the phoneme label of the first language; and a training module 70 for training a seed acoustic model 72 by using the voice data in which the phoneme label of the second language is replaced with the phoneme label of the first language.
