SPEAKER-LIKENESS EVALUATION DEVICE, SPEAKER IDENTIFICATION DEVICE, SPEAKER COLLATION DEVICE, SPEAKER-LIKENESS EVALUATION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a speaker-likeness evaluation device capable of calculating the similarity in speaker's feature vector capable of properly recognizing a speaker even when the length between a registration speech and recognition speech is remarkably different from each other.SOLUTION: The speaker-likeness evaluation device includes: a divided registered speech's speaker feature vector calculation unit 1001 that generates a divided registered speech which has a segment which is shorter than a segment of a registered speech from a registered speech and calculates a divided registered speech's speaker feature vector from the divided registered speech; a recognized speech speaker's feature vector calculation section 1002 that calculates a recognized speech speaker feature vector from a recognized speech; and a similarity calculation section 150 that calculates the similarity between the recognized speech and the divided registered speech by using the recognized speech speaker feature vector and the divided registered speech speaker feature vector.SELECTED DRAWING: Figure 10
