HA Voice - wake word not working

Thanks, it responds to “Hey Mycroft” OK but its not the one I’d like to use. Hey Jarvis works every now and then but its unusable in reality, perhaps it is the way I am saying it, but I’ve tried several different ways of saying the same thing without success.

I have two HA Voice, neither likes Hey Jarvis for some reason. Looking at the assist configuration, I am using home assistant cloud:

PS: “Hey Jarvis” works, but only if I use TTS!
