When I saw the title I was kinda expecting a voice-to-voice translator with voice synth (interpreter), which is something I'm painstakingly building as a side project. I can just drop my project and use a more mature one.
My strategy is to separate everything STT, translation, and TTS, instead of building 1 model (that constantly needs to be trained).
But the problem I am running into is there arent' any great STT or TTS models. Either they only support the top 10 languages, they are huge (whisper-v3-turbo), or non-commercial license (fb's tts/mms models).
Are you training your own models? Just targeting what languages you need? planning on running in the cloud?

I have options to use either Samsung local/offline translation or Google.
Language packs (Sorry for spelling, I don't know how to correctly spell them out in english): Eng/hindi/rus/polish/taju/vietnam/german/arab/french/indonesian/holand/italian/japanese/korea/portugal/spain/turkish/swedish/chinese
Tried it on S22.
