Error switching wake word

I tried to switch to a new wake word like hey jarvis.
However when I switch to it via the CLI I get this erro back:

Hi, I’ve seen that happening if you’re running a different language than en-us (the default). Is this the case for you?

jep thats the problem. So as a fix I did a copy of the en-us folder to the de-de folder and now it works… strange but seems to work wright now but this can’t be the solution?

We should probably add a fallback to the english version we ship if the language specific model doesn’t exist.

yes definitely, since like “hey jarvis” you can’t pronounce this in my case in German so I will still try to say it in “proper” english anyway

I created an issue for it in the mycroft-core repo

If you feel like tackling it you’re welcome to do so.

thx a lot for opening the issue
