Vosk4Unity is a module for the Unity Engine that provides a simple way to integrate speech recognition into your application. It is based on and powered by the Vosk speech recognition engine.

Vosk4Unity can be used with any Vosk-compatible speech recognition model and even provides an in-editor GUI for downloading and managing models. This allows for a very quick and easy setup.

Target Platform Support

The current development version only supports Windows x64 as the target build platform. Eventually, there will be two separate releases. One for targeting Windows 64-bit platforms and one for Windows x86 platforms. Any other target platforms, such as Linux, Android or macOS are currently not supported.

If you do need to build for 32-bit Windows clients, you can use the following work-around for now:

• Download the Windows 32-bit release of the official vosk-api here.
• Go into the folder 'Assets/lib' and replace the .dll files with the ones you downloaded
• Recompile

Vosk for ios | Unity

Can i use Vosk for ios ?

Error on opening the Unity project!

Hi,
I get errors on opening the unity project!
It seems the unity can't read the "Vosk.dll" file in the "lib" folder!
There are three main errors in total that all of them are related to "using Vosk;" in the "VoskListener.cs" script!
Could you please help me to solve this issue?
I am using Unity 2021.1.21f1 (the exact version that you created the project with it)...
I'm looking forward to your comment.
Thank you so much for your attention.
Kind Regards,
Stig

Compiler errors when opening in Unity, Vosk.dll not referenced?

Hello,

First of all, this is a really cool project and exactly what I was looking for for quite a while but unable to do myself, so thanks for doing the work! (I'm looking to use Vosk in a VR game prototype that runs both on Windows and Oculus Quest standalone)

I hope it's okay to open an issue here. I tried opening the project in the correct Unity version, however, I get 3 compiler errors because the types/namespaces 'Vosk', 'VoskRecognizer' and 'Model' can't be found.

I assumed this was caused by the Vosk.dll not loading correctly / not being referenced in the assembly definition for some reason. The assembly definition has indeed a missing reference but I can't reference anything vosk related. I can't include them as assembly references with 'Override References' either.

Also when I tried to enable 'Load on startup' on the vosk.dll and the other libraries in the project, they all throw an exception along the lines of:

Failed to load 'Assets/lib/Vosk.dll', expected x64 architecture, but was Unknown architecture. You must recompile your plugin for x64 architecture.

Vosk is available in 64bit though right? And Unity has phased out 32bit for quite a while now, so I assume something is wrong here and the libraries should not really be 32bit?

Any help would be greatly appreciated!

Cheers, Alex
