20 Claims

1. A system comprising:

one or more microphones;

one or more processors;

at least one non-transitory computer-readable medium; and

program instructions stored on the at least one non-transitory computer-readable medium that, when executed by the one or more processors, cause the system to perform operations comprising:

capturing audio input via the one or more microphones;

monitoring, via a first wake-word detector, the captured audio input for a first wake word associated with a first voice assistant service (VAS);

monitoring, via a second wake-word detector, the captured audio input for a second wake word associated with a second VAS different from the first VAS;

detecting, via the first wake-word detector, the first wake word in the captured audio input;

after detecting the first wake word, obtaining, based on the captured audio input, first content to be played back via a playback device;

playing back, via the playback device, the first content;

while playing back the first content, detecting, via the second wake-word detector, the second wake word in the captured audio input;

after detecting the second wake word:

suspending operation of the first wake-word detector;

obtaining, based on the captured audio input, second content to be played back via the playback device; and

suppressing playback of the first content;

while the playback of the first content is suppressed, playing back, via the playback device, the second content; and

after playing back the second content:

resuming playback of the first content; and

resuming monitoring the captured audio input for the first wake word.
