Wake suppression for audio playing and listening devices
A system and method are disclosed for ignoring a wakeword received at a speech-enabled listening device when it is determined the wakeword is reproduced audio from an audio-playing device. Determination can be by detecting audio distortions, by an ignore flag sent locally between an audio-playing device and speech-enabled device, by and ignore flag sent from a server, by comparison of received audio played audio to a wakeword within an audio-playing device or a speech-enabled device, and other means.
1. An audio extracting device configured to receive an audio signal transmitted to or from an audio device, the audio extracting device comprising:
an input connector configured to receive the audio signal from an input wired connection coupled to the audio extracting device;
an output connector configured to transmit the audio signal to an output wired connection coupled to the audio extracting device, wherein one of the input wired connection and the output wired connection transmit the audio signal to or from the audio device; and
a radio transmitter configured to transmit the audio signal encoded in a wireless signal;
wherein the input wired connection has a first end coupled to the audio extracting device and a second end opposite the first end coupled to the audio device.
2. The audio extracting device of claim 1 , wherein the audio extracting device is configured to form a wireless connection to a speech-enabled device, wherein the wireless signal is configured to provide the audio signal to the speech-enabled device through the wireless connection.
3. The audio extracting device of claim 1 , wherein the audio device is one of a television, stereo and computer.
4. A speech-enabled device comprising:
a microphone configured to capture audio;
a first phrase spotter instance configured to detect a wakeword in audio captured by the microphone;
a radio receiver configured to receive a wireless signal having an encoded audio signal;
a second phrase spotter instance configured to detect the wakeword in the encoded audio signal; and
logic to respond to the wakeword unless the second phrase spotter detects the wakeword before the first phrase spotter detects the wakeword.
5. The speech-enabled device of claim 4 configured to form a wireless connection to an audio extracting device, wherein the encoded audio signal is received through the wireless connection.
6. A speech-enabled device comprising:
a microphone configured to capture audio;
a radio receiver configured to receive a wireless signal having an encoded audio signal;
one or more processors configured to execute software instructions to:
detect a wakeword in the audio captured by the microphone;
detect the wakeword in the encoded audio signal; and
respond to the wakeword unless the one or more processors detect the wakeword captured by the microphone shortly before the one or more processors detect the wakeword encoded in the audio signal.
7. An audio extracting device configured to receive an audio signal transmitted to or from an audio device, the audio extracting device comprising:
an input connector configured to receive the audio signal from an input wired connection coupled to the audio extracting device;
an output connector configured to transmit the audio signal to an output wired connection coupled to the audio extracting device, wherein one of the input wired connection and the output wired connection transmit the audio signal to or from the audio device; and
a radio transmitter configured to transmit the audio signal encoded in a wireless signal;
wherein the output wired connection has a first end coupled to the audio extracting device and a second end opposite the first end coupled to the audio device.
8. The audio extracting device of claim 7 , wherein the audio extracting device is configured to form a wireless connection to a speech-enabled device, wherein the wireless signal is configured to provide the audio signal to the speech-enabled device through the wireless connection.
9. The audio extracting device of claim 7 , wherein the output wired connection has a first end coupled to the audio extracting device and a second end opposite the first end coupled to the audio device.
10. The audio extracting device of claim 7 , wherein the audio device is one of a television, stereo and computer.
