ABSTRACT:
A voice interactive system includes an acoustic processing part11for performing acoustic signal processing with respect to an input voice signal, a voice recognizing part12for recognizing the contents of a voice contained in the voice signal after being subjected to the acoustic signal processing, a voice interacting part13for transmitting information to a user by using a voice output or a combination of a voice output and another information transmission unit based on the contents of the voice, and a barge-in control part14having a barge-in function of suspending the transmission of information based on an input of the acoustic processing part11, an output thereof, or an input signal from an external input, in the course of transmission of information, wherein the barge-in control part14detects at least one feature value from the input signal from the input or the output of the acoustic processing part11or the external input, and determines the effectiveness of the barge-in function based on the at least one feature value.
