Wake-word detection suppression

A method to be performed by a playback device, the method comprising:

• receiving audio content for playback by the playback device;
• providing a sound data stream representing the received audio content to (i) a voice assistant service (VAS) wake-word engine and (ii) a local wakeword engine, wherein the VAS wake-word engine is operable to (a) generate a VAS wake word response when the VAS wake-word engine detects a VAS wake word in a microphone sound data stream representing sound detected by one or more microphones of the playback device and (b) stream sound data representing the sound detected by the one or more microphones to one or more servers of the VAS when the VAS wake word response is generated, and wherein the local wakeword engine is operable to (a) generate a local wakeword response when the local wakeword engine detects one or more local wakewords in the microphone sound data stream representing sound detected by the one or more microphones and (b) determine an intent of a voice input comprising the one or more local wakewords when the local wakeword response is generated;
• playing back a first portion of the audio content via one or more speakers;
• detecting, via the local wakeword engine, that a second portion of the received audio content includes sound data matching one or more particular local keywords;
• before the second portion of the received audio content that includes the sound data matching the one or more particular local wakewords is played back, disabling the local wakeword response of the local wakeword engine to the one or more particular local wakewords during playback of the second portion of the audio content by the playback device;
• and
• playing back the second portion of the audio content via one or more speakers.

A tangible, non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more processors of a playback device, cause the playback device to perform functions comprising:

• receiving audio content for playback by the playback device;
• providing a sound data stream representing the received audio content to (i) a voice assistant service (VAS) wake-word engine and (ii) a local wakeword engine, wherein the VAS wake-word engine is operable to (a) generate a VAS wake word response when the VAS wake-word engine detects a VAS wake word in a microphone sound data stream representing sound detected by one or more microphones of the playback device and (b) stream sound data representing the sound detected by the one or more microphones to one or more servers of the VAS when the VAS wake word response is generated, and wherein the local wakeword engine is operable to (a) generate a local wakeword response when the local wakeword engine detects one or more local wakewords in the microphone sound data stream representing sound detected by the one or more microphones and (b) determine an intent of a voice input comprising the one or more local wakewords when the local wakeword response is generated;
• playing back a first portion of the audio content via one or more speakers;
• detecting, via the local wakeword engine, that a second portion of the received audio content includes sound data matching one or more particular local wakewords;
• before the second portion of the received audio content that includes the sound data matching the one or more particular local wakewords is played back, disabling the local wakeword response of the local wakeword engine to the one or more particular local wakewords during playback of the second portion of the audio content by the playback device;
• and
• playing back the second portion of the audio content via one or more speakers.
