VOICE DOCUMENT SEARCH DEVICE, VOICE DOCUMENT SEARCH METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a speaker specified voice document search technique for which a speaker label is not required.SOLUTION: A plurality of voice documents by a plurality of speakers are stored in a voice document storage part 18. A speaker feature vector space similarity calculation part 14 calculates speaker similarity from the speaker feature vector of a search target speaker and the speaker feature vector of the speaker who has uttered the voice document. A word vector space similarity calculation part 15 calculates text similarity from the word vector of a search target text and the word vector of a recognition result text resulting from the voice recognition of the voice document. A similarity totaling part 16 calculates speaker/text similarity by totaling the speaker similarity and the text similarity. A search result output part 17 outputs the voice document having high speaker similarity.SELECTED DRAWING: Figure 1
