I tried all the applications (open source) for at least six months and did not find anything better than this application ( sherpa-ncnn-2.1.7-cpu-arm64-v8a-en )

I posted your project to everyone on Facebook, but I did not find a solution to this proble.

it is time to build the C++ code of sherpa-ncnn.

Is there a video of this application?

Please describe in detail the issues you have when building sherpa-ncnn.

I looked at it in the past few days but did not find a video on how to install sherpa-ncnn on Android Studio

If you make this video and put it below the Android project

Or prepare it without steps, as the Vosk api developer did

Although your project gives better results than vosk api
You will find unprecedented demand on your platform

I am a forum. I learned Java and Kotlin and worked on projects on Android Studio. The problem is I do not know C++ which files to choose from your project .

This is why your github is not popular because not all people learn C++ or how to add or convert files.

Thank you for your responses and your efforts

We have mentioned it explicitly. The scripts are for linux and macOS.

But you are using Windows. Please follow the instruction in the doc if you are using windows.

You can download pre-built libraries from us and there is no need for you to build them again.

Answer 16 · 2024-02-22T03:25:17.000Z

Which file should I choose?

Answer 17 · 2024-02-22T03:29:17.000Z

You can download an APK, unzip it, and you will find .so inside.

There are APKs for different ABIs; you need to choose the correct one depending on which ABI you want to use.

For instance, if you want to run it on your phone, you would probably select an APK that contains arm64-v8a in its name.

If you want to run with your emulator on Android Studio and your emulator uses x86_64, then you need to select
an APK that contains x86_64 in its name.
