Found Translate You for text translation, but it uses online services. Is there any offline app for that?

Sayboard allows offline speech to text translation. It’s quite cool.
It supports English and seems useful.
Was looking to see if there are models for Malayalam and other languages.

Saw a Malayalam vosk GMM model in gitlab. Tho, it can’t be imported. It seems to need a chain training model.

Does anyone know any resources on that?
Or any other app that can do it?

Or is there some way using Termux or so?
