SPEAKER IDENTIFICATION DEVICE, SPEAKER IDENTIFICATION METHOD, AND RECORDING MEDIUM

摘要

A speaker identification device includes: a primary speaker identification unit that computes, for each pre-stored registered speaker, a score that indicates the similarity between input speech and speech of the registered speakers; a similar speaker selection unit that selects a plurality of the registered speakers as similar speakers according to the height of the scores thereof; a learning unit that creates a classifier for each similar speaker by sorting the speech of a certain similar speaker among the similar speakers as a positive instance and the speech of the other similar speakers as negative instances; and a secondary speaker identification unit that computes, for each classifier, a score of the classifier with respect to the input speech, and outputs an identification result.

1. A speaker identification device comprising:
a primary speaker identification unit which computes, for each registered speaker stored in advance, a score that indicates similarity between input speech and speech of the registered speakers; a similar speaker selection unit which selects a plurality of the registered speakers as similar speakers according to height of the scores; a learning unit which creates a classifier, for each of the similar speakers, by sorting speech of a certain similar speaker among the similar speakers as a positive instance and speech of the other similar speakers as negative instances; and a secondary speaker identification unit which computes, for each classifier, a score of the classifier with respect to the input speech and outputs an identification result.
