AI Text to speech not updating closed captions
When I create a new AI text-to-speech file it adds captions just fine. *
But when I go to update that file on the timeline, even with the "generate CC" box checked, it still has the old captions.
If I delete the existing captions, re-generate the audio with the box checked, and save, no new captions appear.
What can be done about this?
* Also, the AI generation doesn't honor SSML very well. I can't correct its pronunciation of certain words without writing the prompt phonetically, then manually changing the CC every time I update the script.

I haven't used this feature, but I feel your pain with captions and computer pronunciation.
Hi AndrewKrahn,
I understand that you're having difficulty when regenerating your AI TTS Audio as the captions do not update along with the new audio in Storyline 360. I get how confusing that must be! I can confirm that I am not experiencing this on my end, so I'm happy to learn more!
- What voice are you currently using?
- Do you notice any change if you do not manually delete the closed captions prior to audio regeneration?
- Is this happening with any other projects or just this one?
As a troubleshooting step I'm curious if you are able to import any caption files ( Typically they are file types ending in .srt, .vtt, .sbv, and .sub files) when working in the latest version of Storyline 360 (Update 115).
I have also shared your feedback on SSML when working with AI TTS voices with our product team. We'll be sure to share any updates in the future regarding any updates. If you are using v3 we recommend rolling back the model to v2 for more accuracy.
We'd be happy to take a closer look at your .story file within a support case if you are still unable to see closed captions for your re-generated audio.
Looking forward to hearing from you!
I am also experiencing the same behavior as AndrewKrahn
Hi JillJo,
Sorry to hear that you're also experiencing this issue.
I can confirm that we have this behavior logged as a bug in Storyline 360. This bug causes:
- Updating AI & Standard Text-to-Speech does not update the corresponding closed captions.
This behavior does not occur for AI Text-to-Speech if Articulate Localization is enabled. However, this issue occurs consistently for standard Text-to-Speech, regardless of Articulate Localization enablement.
I've included your voice in the bug report so we can notify you as soon as a fix is ready. In the meantime, as a workaround, we suggest:
- Select the Audio from the Slide or Timeline.
- On the top ribbon, navigate to Audio Tools: Options > Closed Captions.
- Delete the existing closed captions.
- Apply the 'Generate with AI option' to create updated closed captions.
Thank you for your patience. I'm sorry if this has been slowing you down!
I just discovered this on one of my projects.. This means that I may have thousands of audio elements with the wrong CC and that I can't trust Storyline to update ANY CC going forward.
Hi MikeAnderson-27,
I'm sorry to hear that you've also encountered this issue. I completely understand the frustration.
Manually removing and regenerating captions for each audio element creates a significant amount of work, so the current workaround may not be practical for larger-scale builds.
I’ve added your feedback to our bug report so the impact on larger projects is clear to our team. We’ll let you know as soon as a fix is available to ship.
Thank you for taking the time to bring this to our attention. I apologize for the inconvenience and extra effort this has caused.
