摘要

PROBLEM TO BE SOLVED: To provide a speech intention model learning device capable of learning a model for properly extracting a speech intention even when speech intention is expressed only in a partial period of a speech.SOLUTION: The speech intention model learning device learns a speech intention N-gram model which is an N-gram model used for extracting a speech intention at every speech by extracting a period as a speech segment, which includes at least one word and continues at an interval smaller than a certain period of time or less; extracting voices in the speech segment as a speech; and using a series of speech intention index in every partial segments which is a row of indexes corresponding to a speech intention in each partial segment, which is a speech intention extracted from each segment included in the speech, and a speech intention label which is given by a person at every time of speech as a learning data.SELECTED DRAWING: Figure 17
