Problem with "Sh"

[IvanRebroff]

Great thing so far, thank's a lot!
I'm trying to set some german wake words, e. g. "Schatzi" which I've tried with "Shutzy". But I only get "Hutzy". So I've tried some englisch words like "Show", "She" and some others and they are also pronounced wrong. Some words like "Sheila" or "Shooter" does work. Strange to me...

This is very strange behavior indeed, @IvanRebroff.

After some testing I traced the issue to the Piper text-to-speech model that openWakeWord uses to generate training data, and I identified a potential solution. But I'm not sure if that fix would cause other problems, so I created an issue in that repo to get some additional feedback.

I'm glad you are finding openWakeWord useful, and I'm very interested to see if your models for German wake words work well! Proper multilingual support is something I hope to have eventually, and while certainly very limited, using english TTS models might work in certain narrow cases like this.

The issue in the piper-sample-generator repo has been addressed, so this issue should be (mostly) resolved with the latest version of that code.
