ONNX format

[frankiedrake]

Is it possible (now or as the future release option) to convert vosk models to an onnx format to reduce the model size?

It is a great idea!

Good) But for now, it's impossible to use ONNX, right?

[nshmyrev]

Yes

I tried to convert vosk model (took file am/final.mdl from model directory, have no idea have I made it right) but for now I didn't succeed. What I did:

main(input_model=os.path.join(model_dir, model_name),
     output=os.path.join(model_dir, new_model_name),
     left_context=3, right_context=3, modulus=1, nnet_type=3)

left_context and right_context took from ivector/splice.conf modulus and nnet_type took from examples somewhere

I got an error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xca in position 32: invalid continuation byte I would suppose it cannot recognize the mdl file but this is just an assumption
