This might be a good fit too

Actually the Descript ai would probably learn other languages than English so much faster when we provide the correct transcript to it

I, too, would LOVE to have this feature. If I could automate the editing process by getting Descript to do its best to relate the audio to the script, mark any additions that I ad-libbed (always brief), and retain the last instance of any given repeated phrase, I'd happily pay double for the service. This has the added benefit of a "perfect" transcription that doesn't need editing: all capitalization, spelling, punctuation, and paragraphing would be found in the final transcript.

Adding to everything that's been said : the auto transcript feature in French is not /that/ good, so uploading the script could help make it like 95% accurate, which would help a lot, mostly for 2 reasons :

This is my #1 feature request as well.

Descript is so close to being the ultimate scripted recoding tool! With its ability to transcribe text it can detect re-takes of sections, or extraneous speech.

With a single click you could auto-edit a whole recording, removing early mistakes and keeping only the last, best take. And if there are still any errors, or misspoken words, you could have Overdub correct those to match the script.

This would be great for setting up voiceover recording lines, then handing the project to the voice actor.

100% this. Even better if this could happen inside a mobile app, maybe not fully featured for editing, but at least for interview recording & scripted recording. (I can't record on my laptop because the fan is so damn loud, especially the second you open Descript...)
