Patent ID: 7107217

Claim:
A voice interactive system, comprising: a voice information input part inputting voice information of a first user from a first user terminal; a voice recognition part conducting voice recognition with respect to the voice information and analyzing contents of the voice information; a voice information medialion part controlling a transmission path of the voice information in accordance with the analyzed contents of the voice information; an interaction engine extracting contents of a response corresponding to the voice information by referring to a knowledge database and creating a synthesized voice in accordance with the extracted contents of the response; and a voice information output part outputting the synthesized voice, wherein the voice information mediation part monitors at all times an average reaction time, from a response of the interaction engine to a reaction of the first user, and in each of a case where the average reaction time exceeds a first threshold value that is an upper limit of a reaction time in an ordinary interaction and a case where the average reaction time is below a second threshold value that is a lower limit of the reaction time in the ordinary interaction, determines that an interaction between the first user and the interaction engine is not being smoothly conducted and allows a third-party user to participate in the interaction between the first user and the interaction engine, as a helper, from a terminal other than the first user terminal.
