Use Vosk models in Spokestack

I tried the vosk api models on my laptop, which have been great! For a react native project I wanted to use spokestack, which is a library/company that connects NLU, ASR and TTS in a nice pipeline. For testing accuracy I want to try to implement a vosk model.

They use a model that is made with tensorflow lite,

The output is:
- A tensorflow lite model
- A vocab file (txt)
- A metadata json file

Is there a way to implement the vosk model for spokestack?
