Abstract

A system comprises an apparatus having a first voice I/O device; and a voice interface apparatus having a second voice I/O device, and connected to the apparatus by audio connection via short-range wireless communication, wherein the apparatus includes a voice I/O unit that performs voice input and output by using the first voice I/O device or the second voice I/O device; an interaction unit that performs voice interaction with a user; and a process unit that performs a process other than the voice interaction, by using the voice I/O, and the voice I/O unit switches a device used for the voice input and output to the first voice input/output device in a case where the process unit is brought into a first state in which the voice input and output is required when the voice interaction with the user is performed by using the second voice I/O device.

First claim

What is claimed is:

1. A voice interaction system comprising:
an information processing apparatus having a first voice input/output device configured to input sound and output sound; and
a robot that includes a voice interface apparatus having a second voice input/output device configured to input sound and output sound, and connected to the information processing apparatus by audio connection via short-range wireless communication, wherein
the information processing apparatus includes:
a voice input/output unit configured to perform voice input and output by using the first voice input/output device or the second voice input/output device;
an interaction unit configured to perform voice interaction between a user and the robot; and
a process unit having a communication section configured to perform a voice call between the user and a third party via a communication network, by using the voice input and output, and
the voice input/output unit switches a device used for the voice input and output to the first voice input/output device in a case where, due to an incoming communication from the third party, the process unit is brought into a first state in which the voice input and output via the communication section is required to perform the voice call between the user and the third party at a time at which the voice interaction between the user and the robot is being performed by using the second voice input/output device.

2. The voice interaction system according to claim 1 , wherein
the communication section performs the voice call via a wireless communication network.

3. The voice interaction system according to claim 1 , wherein
the information processing apparatus and the voice interface apparatus are connected to each other by using a voice profile based on a Bluetooth standard.

4. The voice interaction system according to claim 3 , wherein
the process unit transmits a first notification to the voice interface apparatus in the case where the process unit is brought into the first state, and
the voice interface apparatus terminates the audio connection with the information processing apparatus in a case where the voice interface apparatus receives the first notification.

5. The voice interaction system according to claim 1 , wherein
the process unit transmits a second notification to the voice interface apparatus in a case where the voice input and output becomes unnecessary, and
the voice interface apparatus re-establishes the audio connection with the information processing apparatus in a case where the voice interface apparatus receives the second notification.

6. The voice interaction system according to claim 3 , wherein
the process unit transmits a first notification to the voice interface apparatus in the case where the process unit is brought into the first state, and
the voice interface apparatus transmits a rejection response to the process unit, and then terminates the audio connection with the information processing apparatus in a case where the voice interface apparatus receives the first notification.

7. The voice interaction system according to claim 6 , wherein
when the process unit receives the rejection response and the audio connection is terminated, the process unit re-establishes the audio connection by transmitting a second notification to the voice interface apparatus in a case where the voice input and output becomes unnecessary.

8. An information processing apparatus comprising:
a first voice input/output device configured to input sound and output sound;
a voice input/output unit configured to perform voice input and output by using the first voice input/output device or a second voice input/output device of a voice interface apparatus of a robot connected to the information processing apparatus via short-range wireless communication, the second input/output device of the robot being configured to input sound and output sound;
an interaction unit configured to perform voice interaction between a user and the robot; and
a process unit having a communication section configured to perform a voice call between the user and a third party via a communication network, by using the voice input and output, wherein
the voice input/output unit switches a device used for the voice input and output to the first voice input/output device in a case where, due to an incoming communication from the third party, the process unit is brought into a first state in which the voice input and output via the communication section is required to perform the voice call between the user and the third party at a time at which the voice interaction between the user and the robot is being performed by using the second voice input/output device.

9. The voice interaction system according to claim 1 , wherein
the interaction unit performs the voice interaction with the user by sending a voice response that was generated in response to a voice utterance using voice recognition and response sentence generation, the voice utterance and the voice response being received and sent through one of the first and second voice input/output devices.

10. The information processing apparatus according to claim 8 , wherein
the interaction unit performs the voice interaction with the user by sending a voice response that was generated in response to a voice utterance using voice recognition and response sentence generation, the voice utterance and the voice response being received and sent through one of the first and second voice input/output devices.
