US 7412382 B2Abstract
A voice interactive system includes an acoustic processing part 11 for performing acoustic signal processing with respect to an input voice signal, a voice recognizing part 12 for recognizing the contents of a voice contained in the voice signal after being subjected to the acoustic signal processing, a voice interacting part 13 for 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 part 14 having a barge-in function of suspending the transmission of information based on an input of the acoustic processing part 11, an output thereof, or an input signal from an external input, in the course of transmission of information, wherein the barge-in control part 14 detects at least one feature value from the input signal from the input or the output of the acoustic processing part 11 or the external input, and determines the effectiveness of the barge-in function based on the at least one feature value.
Therefore, with the foregoing in mind, it is an object of the present invention to provide a voice interactive system and method highly convenient for a user, by suppressing unexpected barge-in caused by various echoes and noise and the malfunction of a system due to the erroneous recognition caused by the barge-in.
FIG. 1 is a view showing a configuration of a voice interactive system according to an embodiment of the present invention.
Hereinafter, a voice interactive system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a view showing a basic configuration of the voice interactive system according to the embodiment of the present invention.
Next, the voice interacting part 13 outputs desired information to a user based on the voice recognition result in the voice recognizing part 12. As an output method (information transmission method), a voice output by a synthetic voice or the like, or a combination of a voice output and another information transmission unit is considered. “Another information transmission unit” refers to an information transmission unit based on, for example, an image, a voice, light, vibration, and the like.
Herein, the “predetermined time” may be, at most, a time between the commencement of a voice output from the voice interacting part 13 and the commencement of barge-in by a user's voice input, or a previously set time. In the latter case, the predetermined time needs to be set, assuming a time before the commencement of barge-in by the voice input by a user.
