German is not well recognized

Hello, everybody,

I have the problem that german is not really well recognized. I have tried pocketsphinx, which is fast but fails to 80%. Kaldi on the other hand is more accurate in German, but takes much longer and fails 50%. Is there any way to improve certain languages besides english?

Thanks for suggestions

You can tweak the decode.sh script used for Kaldi decoding to improve WER. See:

I suggest increasing acoustic scale, beam and/or max-active (these worked for me). I’m no expert though.

Hope this helps.
