Storyline AI Voice - decreasing volume
Hi,
Consider this feedback for the implementation of AI voice over provided by ElevenLabs inside Storyline 360.
I've been typically noticing this on any voice over that lasts approx. 50 seconds or longer, but I have also noticed this continuously gradual decrease in volume in clips as short as 40 seconds.
If the generated voice over is long enough, the audio can, over its duration, gradually decrease to barely perceptible levels.
This means constantly having to chop up the script and generating multiple short clips for a single slide or layer.
I've tried on new slides, tried in a blank and clean project with the same results.
Kind regards,
sam

Hey SamBarnard-98a4,
Sorry to hear that AI Voiceovers in Storyline are not playing back as expected.
I tested this on my end using a 1min34sec track, dictated by Laura. After previewing and publishing to Review, the volume remained consistent throughout playback. I'm happy to help troubleshoot this further and have some follow-up questions to start:
- Are you noticing this issue across all published output (LMS, Review, etc.), or is it specific to one format?
- Do you see this behavior among all voices? We are tracking a Storyline bug that causes this same behavior when the Rachel voice is used.
If a repair of your Storyline installation doesn't improve the behavior, do you mind uploading one of the affected .story files so we can take a closer look? If you prefer to share that privately, please connect with us through a support case.
Hi,
Thank you for the response.
I was using the voice Max - Elearning and Documentary when I noticed this behaviour and I did see a thread once before that identified this behaviour as well (don't recall seeing a specific voice being mentioned).
Currently I've not bothered publishing the content because the voice over is decreasing in volume - I'm not going to waste time publishing something with a known issue that I will have to still fix.
I have just tested this again in a fresh project file with a different script from Wikipedia's article on Lorem Ipsum - see attachment. Afraid I cannot share the original build where this problem occurred as it contains company IP.
Two things I did not mention in my original post:
- The behaviour was worse and really noticeable on slides where I used line breaks to separate out paragraphs of the script, especially in instances of 3 or more 'paragraphs'. It still happened without these breaks, it was just more noticeable with them in.
- I was using the multilingual v2 model as it sounds better and I have more control, especially for speed, than v3. V3 is lacking this control and needs it.
Repair of Storyline has not resolved the issue.
Kind regards,
Sam
Hey SamBarnard-98a4,
You're welcome. Thanks for following up and sharing a sample file.
After testing your example, I had the same experience. The audio greatly decreased during playback. I understand that you've been using the Max voice. Unfortunately, that is one of the voices that was retired last month. Behavior such as this can be expected when using a voice that is no longer supported by Storyline.
Using your same script and paragraph formatting, I ran a test with a different voice (Matilda). On Slide 1.2, I did not observe any volume issues during preview or when publishing to Review 360. I've attached a copy of the file I used in my testing, with my reply.
We understand losing access to certain voices can be disruptive, and I'm sorry if this has been slowing you down. Moving forward, I suggest using a different voice in your build if possible.
Please let me know if you need anything else!
