摘要

PROBLEM TO BE SOLVED: To replay sound of re-listen efficiently.SOLUTION: In a voice interaction support device 100, a division unit 102 divides audio data including words and sounds depending on characteristics not less than 1 of word and acoustic characteristics, and acquires several divided audio data. An analyzer 103 acquires analysis about the word and acoustic characteristics for each divided audio data. An expression detecting unit 105 detects clue expression not less than 1 indicating either indication of a user or state of the user for each divided audio data by at least either utterance by the user or action by the user. When the clue expression is detected, an estimation unit 108 estimates the divided audio data as replay data not less than 1 from the divided audio data not less than 1 corresponding to the sound uttered before the clue expression is detected based on the analysis. An output unit 110 outputs the replay data.
