I am trying to change the wake word for Mycroft to hey bob. I set it in https://home.mycroft.ai to HH EY .B AA B it works, however, it comes with an extra caveat. It for some reason without any noise happening will just randomly act like the wake word has been said, so I will hear “sorry I didn’t catch” that constantly.
You need to adjust the threshold in the advance settings on home.mycroft.ai. It might take some experimenting to get it to your liking, though. I believe increasing the setting (e.g. changing from 1e-90 to ie-50) reduces the sensitivity, but I might have that backwards. (wink!)
