摘要

PROBLEM TO BE SOLVED: To perform highly accurate language identification.;SOLUTION: A learning data storage part 1 stores a plurality of learning data items composed of groups of voice data by a plurality of languages combined with language labels representing languages of the respective voice data. A conversion model learning part 2 uses the learning data to learn a discrete symbol sequence conversion model outputting a discrete symbol sequence discretizing a posterior probability distribution of language labels with the voice data as input. A discrete symbol sequence conversion part 4 uses the discrete symbol sequence conversion model to convert the voice data of the learning data into a discrete symbol sequence. A language identification model learning part 5 uses the discrete symbol sequence of the learning data and the language labels to make the discrete signal sequence of the voice data input, and learns a language identification model outputting generation probability every language label.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
