Turn-taking timing identification device, turn-taking timing identification method, program, and recording medium

摘要

PROBLEM TO BE SOLVED: To provide turn-taking timing information technology using a feature amount extracted from information of past speeches before the last time without manually designing a feature amount extraction rule.SOLUTION: A turn-taking timing identification apparatus comprises: a voice section detection section for detecting speech k from input voice; an in-speech feature amount sequence generation section for generating an in-speech feature amount sequence K from the speech k; a speech feature amount calculation section for calculating a speech feature amount k from the in-speech feature amount sequence k; a turn-taking point feature amount calculation section for calculating a turn-taking point feature amount k from time-series data constituted of a speech feature amount i (i=1,...,k-1) and the speech feature amount k, which are previously calculated; and a turn-taking timing identification section for generating an identification result k showing whether the turn-taking point k is turn-taking timing or not from the turn-taking point feature amount k. The speech feature amount calculation section and the turn-taking point feature amount calculation section are constituted by using a neural network where time-series data is set to be input and the feature amount is outputted.SELECTED DRAWING: Figure 2
