Title:
PARALANGUAGE INFORMATION ESTIMATION DEVICE, METHOD FOR ESTIMATING PARALANGUAGE INFORMATION, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/085070
Kind Code:
A1
Abstract:
The present invention makes it possible to improve the accuracy in estimating paralanguage information. A paralanguage information estimation model storage unit 20 stores a paralanguage information estimation model that uses a plurality of independent feature amounts as input and outputs paralanguage information estimation results. A feature amount extraction unit 11 extracts a feature amount from an input utterance. A paralanguage information estimation unit 20 estimates the paralanguage information of the input utterance from the feature amount extracted from the input utterance using the paralanguage information estimation model. The paralanguage information estimation model comprises: a feature amount sub-model that outputs information used for estimating paralanguage information for each feature amount on the basis of only the feature amount; a feature amount weight calculation unit that calculates a feature amount weight for each feature amount on the basis of the output result from the feature amount sub-model; a feature amount gate that assigns a weight to the output result from the feature amount sub-model for each feature amount using the feature amount weight, and outputs the weighted results; and a result integrating sub-model that estimates paralanguage information on the basis of the output result from all the feature amount gates.
