Odd AI audio issue

Hi everyone,

I’m hoping someone can help with an issue I’ve encountered while developing French versions of courses.

In multiple courses, the French AI-generated audio plays correctly, but the automatically generated closed captions appear in English. In each case, the workflow was:

1. Develop the English version of the course.
2. Create a copy for the French version.
3. Export the Word document, translate it, and import the translated content.
4. Regenerate the AI audio in French.

The Generate Closed Captions option remained selected throughout the process (it is enabled by default). However, for some reason, the captions generated are still in English while the audio is French.

I can resolve the issue by recreating the AI audio slide by slide, which also regenerates the captions correctly. However, I’ve noticed another problem: the newly generated audio is a different length than the original, even when using the same voice, speed, and all other settings.

To troubleshoot, I tried several approaches, including:

• Generating completely new AI audio from the translated slide content.
• Using the Notes section to create new audio.
• Recreating audio through the existing AI Text-to-Speech settings while ensuring all voice and playback settings matched the original.

Despite using the same settings and text, the regenerated audio lengths are different, which impacts animation timing throughout the course.

My questions are:

• Is there a faster way to update or regenerate closed captions that are in the wrong language without recreating the audio on every slide?
• Has anyone experienced captions being generated in English while using French AI audio?
• Does anyone know why AI text-to-speech audio length would differ when regenerated using the same voice and settings?
• Will I need to recreate the audio and adjust animations slide by slide, or is there a more efficient solution?

Any insights or recommendations would be greatly appreciated. Thanks in advance!
