• vosk-model-en-us-0.22 (~1.8GB) - Better accuracy, slower

Troubleshooting

Mod not working:

• Check BepInEx/LogOutput.log for errors
• Ensure all DLLs are in the plugin folder (libvosk.dll, libgcc_s_seh-1.dll, libstdc++-6.dll, libwinpthread-1.dll)
• Verify at least one model folder exists in the model/ directory

Low accuracy:

• Speak clearly and at a moderate pace
• Check microphone quality
• Consider downloading and changing to vosk-model-en-us-0.22 or vosk-model-en-us-0.42-gigaspeech for better accuracy

No audio transmission:
