This seems exactly what the Rhasspy project is doing. They're combining the language model from user-supplied `sentences.ini` together with the general language model with some weighting factor: 

Awesome! I would like to integrate what `sphinx_jsgf2fsg` and `fstcompile` are doing directly into `vosk-api`'s code (compile those tools as static libraries and link with them). Thoughts?

After calling `media_player.stop` the error went away. I suspect restarting the device would also fix it.
