Abstract

According to one embodiment, a sound recognition operation apparatus includes a sound detection module, a keyword detection module, an audio mute module, and a transmission module. The sound detection module is configured to detect sound. The keyword detection module is configured to detect a particular keyword using voice recognition when the sound detection module detects sound. The audio mute module is configured to transmit an operation signal for muting audio sound when the keyword detection module detects the keyword. The transmission module is configured to recognize the voice command after the keyword is detected by the keyword detection module, and transmit an operation signal corresponding to the voice command.

Claims

1. A sound recognition operation apparatus comprising:

a sound detection module configured to detect sound;

a keyword detection module configured to detect a particular keyword using voice recognition when the sound detection module detects the sound;

an audio mute module configured to transmit an operation signal for muting audio sound when the keyword detection module detects the keyword; and

a transmission module configured to recognize a voice command after the keyword detection module detects the keyword, and to transmit an operation signal corresponding to the voice command.

2. The sound recognition operation apparatus of claim 1, further comprising a notification controller configured to perform control so that when the sound detection module detects the sound, the notification controller notifies that the voice recognition operation apparatus is waiting for a keyword.

3. The sound recognition operation apparatus of claim 2, wherein the notification controller uses at least one of voice and display to perform control so as to notify that the voice recognition operation apparatus is waiting for a keyword.

4. The sound recognition operation apparatus of claim 1, wherein the keyword detection module is configured to detect a keyword by voice recognition only in a predetermined period of time since the sound detection module detects the sound.

5. The sound recognition operation apparatus of claim 1, wherein the transmission module is configured to recognize a voice command only in a predetermined period of time since the keyword detection module detects the keyword.

6. The sound recognition operation apparatus of claim 1, wherein the sound detection module is configured to detect a clapping sound.

7. The sound recognition operation apparatus of claim 6, wherein the sound detection module is configured to detect a successive clapping sound of a predetermined number of claps or more.

8. The sound recognition operation apparatus of claim 1, wherein the transmission module is configured to transmit an operation signal for automatically changing a channel with a predetermined interval of time when the voice command recognized by the voice recognition is determined to be a request for starting surfing.

9. The sound recognition operation apparatus of claim 1, wherein the transmission module is configured to stop transmission of the operation signal for changing the channel, and continuously tune in on the channel currently selected at that moment when the voice command recognized by the voice recognition is determined to be a request for stopping surfing.

10. The sound recognition operation apparatus of claim 8, wherein the transmission module is configured to change the interval with which the operation signal for changing the channel is transmitted when the voice command recognized by the voice recognition during the surfing is determined to be a request for changing an interval for changing the channel.

11. The sound recognition operation apparatus of claim 8, further comprising a notification module configured to notify that surfing is being performed.

12. A sound recognition operation method comprising:

causing a sound detection module to detect sound;

causing a keyword detection module to detect a particular keyword using voice recognition when the sound detection module detects the sound;

causing an audio mute module to transmit an operation signal for muting audio sound when the keyword detection module detects the keyword; and

recognizing a voice command after the keyword detection module detects the keyword, and causing a transmission module to transmit an operation signal corresponding to the voice command.
