Willow with on device wake word

[janstadt]

Just curious if there has been any thought in to doing on device wake word detection via microwakeword? I find that it is more effective compared to openWakeWord currently (via native HA Voice). I havent tested it out via willow but was curious if anyone has or if this is even an option?

So the wake word processing is done on device (on the ESP Box) in willow, using the ESP-ADF libraries. We have a few different configurable wakewords, with more on the way :)

Ah ok thanks. Just curious, how is it doing the wake word detection?

Not really sure how to answer, it's just part of the ESP-ADF libraries. It loads the model and the device listens for it. Once it hears it, that triggers it to start streaming to the inference server and wait for VAD to end listening. I imagine microWakeWord is using the same libraries, but I am not certain as I haven't looked at it in great detail.
