Abstract
A voice interaction system includes: a speaker; a microphone having a microphone gain that is set at a low level while a sound is output from the speaker; a voice recognition unit that implements voice recognition processing on input sound data input from the microphone; a sound output unit that generates output sound data and outputs the generated output sound data through the speaker; and a non-audible sound output unit that, when a plurality of sounds are output with a time interval no greater than a threshold therebetween, outputs a non-audible sound through the speaker at least in the interim between output of the plurality of sounds.
