Answer 1

It is great you tried Vosk offline speech recognition on Android, here are some answers to your questions:

actually I read it still doesn't support my native language.

If you are about Hebrew, we might support it in the future, and you can build it yourself.

is that the reason?

You didn't provide enough information to answer this, please explain a bit more what is "it is not work"

I want to know how it works?

Extensive documentation on speech recognition is available on lectures, courses and books. You can find some introduction here for example: https://www.youtube.com/watch?v=q67z7PTGRi8

does it is doing speech to text and saved it in assets files?

It does speech to text, but it doesn't save results into assets, it just displays them. You can not modify assets, they are static.

does it is run in background?

Yes

does it is used AI models?

Sure

how it behaves when two apps need mic resource in parallel?

In android it is not possible to record audio from two apps in parallel, second one will be blocked.

noises?

It is robust to noises.

does it is work with Neural Networks API?

No, it is portable

how can I start developing such a thing?

Get some basic understanding and start writing the code. If you have further questions you can ask them in the Telegram chat
