Networked devices, systems, & methods for intelligently deactivating wake-word engines

A tangible, non-transitory, computer-readable medium having instructions stored thereon that are executable by one or more processors to cause a playback device to:

• identify in an audio stream, via a second wake-word engine, a false wake word for a first wake-word engine that is configured to receive as input sound data based on sound detected by at least one microphone of the playback device, wherein the first wake-word engine is configured according to a first sensitivity level for false positives of a particular wake word, and wherein the second wake-word engine is configured according to a second sensitivity level for false positives of the particular wake word that is more sensitive than the first sensitivity level;
• based on identifying the false wake word, (i) deactivate the first wake-word engine and (ii) cause, via a network interface of the playback device, at least one network microphone device to deactivate a wake-word engine of the at least one network microphone device for a particular amount of time;
• while the first wake-word engine is deactivated, cause at least one speaker of the playback device to output audio based on the audio stream;
• and
• after a predetermined amount of time has elapsed, reactivate the first wake-word engine.

A computer-implemented method comprising:

• identifying in an audio stream, via a second wake-word engine of a playback device, a false wake word for a first wake-word engine that is configured to receive as input sound data based on sound detected by at least one microphone of the playback device, wherein the first wake-word engine is configured according to a first sensitivity level for false positives of a particular wake word, and wherein the second wake-word engine is configured according to a second sensitivity level for false positives of the particular wake word that is more sensitive than the first sensitivity level;
• based on identifying the false wake word, (i) deactivating the first wake-word engine and (ii) causing, via a network interface of the playback device, at least one network microphone device to deactivate a wake-word engine of the at least one network microphone device for a particular amount of time;
• while the first wake-word engine is deactivated, causing at least one speaker of the playback device to output audio based on the audio stream;
• and
• after a predetermined amount of time has elapsed, reactivating the first wake-word engine.
