German letter ß converted to ss #85
Description
Hello,
I got a problem which is driving me crazy and i cannot fix it so far.
I am using vosk in my home assistant setup and i turned the "Limit sentences" option on and provided a de.yaml file with german sentences.
It is all working pretty good and i love it, that its so fast and recognizing the spoken so well.
But when i use the german letter ß, e.g. in the word dreißig (which is german for thirty), I get the following warning in the logs of my vosk addon: WARNING (VoskAPI:UpdateGrammarFst():recognizer.cc:308) Ignoring word missing in vocabulary: 'dreissig'
It seems to me that somewhere in the pipe the ß letter is corrected to ss. But than my german language model (https://huggingface.co/rhasspy/vosk-models/blob/main/_vocab/vosk-model-small-de-0.15.txt) is not knowing the word, because it is written wrong.
Someone else got this problems or knows how to deal with it? I am thankfull for any help.
P.S. this is my first issue that i ever opened. So please let me know when you are missing something.
