Translation / localization

Hi,
We currently have our course in English only, but more and more we get requests to translate the content. The content is mostly text and speech (generated with the text to speech feature).

I know about the feature on how to export, translate and import again, but now with AI and LLM and translation tools like DeepL is there a smarter and easier way to do it than duplicating slides and courses in different languages?

Anyone with ideas, experience or suggestions? I am happy to hear what you think.
