PARALINGUISTIC INFORMATION ESTIMATION MODEL LEARNING APPARATUS, PARALINGUISTIC INFORMATION ESTIMATION APPARATUS, AND PROGRAM

摘要

Paralinguistic information is estimated with high accuracy even when an utterance for which it is difficult to identify paralinguistic information is used for model learning. An acoustic feature extraction unit 11 extracts an acoustic feature from an utterance. An anti-teacher decision unit 12 decides, based on a paralinguistic information label indicating a determination result of paralinguistic information given by a plurality of listeners for each utterance, an anti-teacher label indicating an anti-teacher serving as incorrect paralinguistic information for the utterance. An anti-teacher estimation model learning unit 13 learns, based on an acoustic feature extracted from the utterance and the anti-teacher label, an anti-teacher estimation model for outputting a posterior probability of anti-teacher for an input acoustic feature.
