Patent ID: 11798578

Abstract:
To increase the accuracy of paralinguistic information estimation. A paralinguistic information estimation model storage unit 20 stores a paralinguistic information estimation model outputting, with a plurality of independent features as inputs, paralinguistic information estimation results. A feature extraction unit 11 extracts the features from an input utterance. A paralinguistic information estimation unit 20 estimates paralinguistic information of the input utterance from the features extracted from the input utterance, by using the paralinguistic information estimation model. The paralinguistic information estimation model includes, for each of the features, a feature sub-model outputting information to be used for estimation of paralinguistic information, based only on the feature, for each of the features, a feature weight calculation unit calculating a feature weight, based on an output result of the feature sub-model, for each of the features, a feature gate weighting the output result from the feature sub-model with the feature weight and outputting a result, and a result integration sub-model estimating the paralinguistic information, based on output results from all the feature gates.
