1. A method comprising:
detecting sound via one or more microphones of at least one network microphone device to obtain sound data;
detecting, via a first wake-word engine, a first wake word in the sound data and generating a first wake-word event, the first wake word associated with a first voice assistant service (VAS);
detecting, via a second wake-word engine, a second wake word in the sound data and generating a second wake-word event, the second wake word associated with a second VAS different from the first VAS;
when the first wake word and the second wake word are detected within a first period of time, disregarding both the first wake-word event and the second wake-word event; and
after expiry of the first period of time, continuing to analyze detected sound via both the first wake-word engine for wake word detection of the first wake word and the second wake-word engine for detection of the second wake word.
