SYSTEM, PROCESSING METHOD, AND PROGRAM FOR SIMILAR VOICE MUSIC SEARCH, RECORDING MEDIUM OF PROGRAM

摘要

PROBLEM TO BE SOLVED: To precisely and quickly search a voice music signal containing unsteady noise.

SOLUTION: A short time window voice music feature value extracting part 11 extracts a short time window voice music feature value from a voice music signal of a search key using a short time window. A short time window voice music feature value similarity search part 12 searches a short time window voice music feature value having high partial similarity from the short time window voice music feature value which has been accumulated as a search target, using the extracted short time window voice music feature value. A voice music information comparison consolidating part 13 cuts a candidate answer voice music section out of the voice music signal which is to be searched based on the results of similarity searching, and calculates overall similarity between the candidate answer voice music section and the search key. A voice music display output device 21 displays the list of the candidate answer voice music sections in order of overall similarity, with highest similarity being first, and outputs the voice music signal in the specified section.
