Voice interaction apparatus and automatic interaction method using voice interaction apparatus
First Claim
1. A voice interaction apparatus comprising:
- an interactive robot comprising;
a pseudo head;
a microphone configured to detect an input speech spoken by a user;
a speaker configured to output an output speech spoken to the user; and
a processor configured to;
estimate a change probability that indicates whether to wait for the input of the input speech by the microphone, or to execute the output of the output speech by the speaker, based on the input speech detected by the microphone; and
if the change probability falls within a predetermined subset range, control the voice interaction apparatus to respond by executing at least one of a filler output and a nodding action,wherein the filler output is an output of a filler from the speaker, the filler being a connecting utterance irrelevant to an interaction content, andwherein the nodding action is an action of swinging the pseudo head back and forth.

Abstract
Provided is a voice interaction apparatus including an estimation unit configured to estimate whether to wait a next user'"'"'s speech or to execute an output of an output speech by the voice interaction apparatus based on a user'"'"'s speech input by an input unit; and the response control unit configured to, when the estimation unit could not estimate whether to wait for the user'"'"'s next speech or to execute the output of the output speech by the voice interaction apparatus, respond by executing at least one of a filler output and a nodding action, the filler output being an output of a filler, i.e., a connecting utterance irrelevant to an interaction content, from the output unit, and the nodding action being an action of swinging a pseudo head part back and forth.

6. An automatic interaction method using a voice interaction apparatus including a microphone configured to detect an input speech spoken by a user and a speaker configured to output an output speech spoken to the user, the automatic interaction method comprising:
-
estimating, with a processor, a change probability that indicates whether to wait for the input of the input speech by the microphone or to execute the output of the output speech by the speaker based on the input speech detected by the microphone; determining, with the processor, that the change probability falls within a predetermined subset range; and responding by executing, when the change probability falls within the predetermined subset range, at least one of a filler output and a nodding action, the filler output being an output of a filler from the speaker, wherein the voice interaction apparatus is an interactive robot that further includes a pseudo head, wherein the filler is a connecting utterance irrelevant to an interaction content, and wherein the nodding action is an action of swinging the pseudo head back and forth.
