ONNX infer

[pengpengtao]

Does this model support ONNX inference?

[csukuangfj]

Yes.

I suggest that you have a look at https://github.com/k2-fsa/sherpa-onnx/blob/master/scripts/melo-tts/export-onnx.py

We support exporting MeloTTS models to onnx.

You can use https://github.com/k2-fsa/sherpa-onnx/blob/master/scripts/melo-tts/test.py to test your exported onnx model.

Furthermore, we also provide a C++ runtime for it and support 10 programming languages.

You can try the exported MeloTTS Chinese+English ONNX model on your Android phone by downloading the APK from

https://k2-fsa.github.io/sherpa/onnx/tts/apk-engine.html

@csukuangfj Good news! Are there any plans for a Korean Onnx version?

[csukuangfj]

You can have a look at how we convert the Chinese+English model. The way for converting Korean should be similar.

[csukuangfj]

We already have a Korean tts model at https://github.com/k2-fsa/sherpa-onnx/releases/download/tts-models/vits-mimic3-ko_KO-kss_low.tar.bz2 So we don't plan to convert the Korean model from MeloTTS soon.

@csukuangfj I will analyze the Chinese + English version and attempt to perform inference on the Korean ONNX version. Thank you!

[m-bain]

@eehoeskrap any success?

[khacpv]

@csukuangfj I tried to convert JP language by edit export-onnx.py#L225 from ZH to JP but not successful.

Could you help me check? Thank you.

Sorry, the info you give is toooo limited.

Please see https://github.com/csukuangfj/sherpa-onnx/actions/runs/10537349904/job/29198651417#step:4:936

-rw-r--r-- 1 runner docker 163M Aug 24 09:13 model.onnx

You can see that by changing to JP you can successfully convert the model to onnx.

(You need to handle tokens.txt and lexicon.txt for Japanese).

@csukuangfj I can run and get model.onnx as following:

Do you have any instruction for handle this files?

[csukuangfj]

You have to figure them out by yourself. We have already provided you an example for Chinese+English.
