Add support for other languages

[autotunafish]

Requesting support for Portuguese in particular. Otherwise exposing the other optional languages supported by LibreTranslate in the hosted, non-docker version would be helpful

Hi @autotunafish, you are right that LibreTranslate supports more languages than are currently offered. The options are currently limited by the availability of good STT and TTS models for the other steps.

I see. Would an option that only enables the STT side to be printed into the chat box be possible? I think I may have been under the impression that was how it already worked, w/o the translated audio recreation.
