In the model after training there isn't ivector folder.

[chungtran2000]

After successfully running the file train.py I get the files mfcc.conf, final.mdl,HCLG.fst, words.txt, .... But compared to the folder downloaded from "https://alphacephei.com/vosk /models" I see the ivector folder is missing. And when I put it into the Android project I got an error: Failed to create model. What do I need to do to fix this error?

Which train.py do you run?

[chungtran2000]

I made the model following this tutorial: "https://github.com/undertheseanlp/automatic_speech_recognition".
The train.py file that I run is located at the project's path:"automatic_speech_recognition/egs/vivos".

That setup is not sufficient. Our training demo is here, you need to follow it instead:

Thank you so much. Do you have specific instructions for this?

No instructions, you can just run it locally or in colab. Let us know if you have any questions
