I am a teacher and have students who speak many different languages. The most common ones are Chinese, Spanish and Portuguese, but we have other folks speaking other languages as well.
I wish to translate all my notes, lecture subtitles, and topic-exercise documents to other languages. Moreover every year, I have to update my teaching material and include new stuff. So, muddling though everything manually is not much of an option as it might take up to two months just for this task.
Are there nice self hosted and libre/open source solutions out there for this task?
You can self-host libretranslate: https://libretranslate.com/
Looks like the engine behind it is https://opennmt.net/
Which can use a Tensor Flow backend, which can potentially be accelerated by a rather cheap Coral TPU. Neat!
