Abstract
An audio analysis system includes a terminal apparatus and a host system. The terminal apparatus acquires an audio signal of a sound containing utterances of a user and another person, discriminates between portions of the audio signal corresponding to the utterances of the user and the other person, detects an utterance feature based on the portion corresponding to the utterance of the user or the other person, and transmits utterance information including the discrimination and detection results to the host system. The host system detects a part corresponding to a conversation from the received utterance information, detects portions of the part of the utterance information corresponding to the user and the other person, compares a combination of plural utterance features corresponding to the portions of the part of the utterance information of the user and the other person with relation information to estimate an emotion, and outputs estimation information.
