Changing Speed of Audio in Articulate Storyline?
I'm working on creating some Articulate Storyline projects for a class I teach. Our current videos are MUCH less engaging and interactive and are simply the professor in front of a web camera lecturing. One things students LOVE to do is to speed up the audio / presentation of the video. Most students can listen and absorb items much faster than we can talk about them. I have some audio/lecturing slides in Storyline (e.g. when I do a voice-over of a screen capture or talk about the basics of financial statements). I'm wondering if there is anything I can add to the player that would allow students to control the speed of the audio.
Hi, everyone!
I have some great news to share. We just released another update for Storyline 360. In Update 83, we've included important fixes and new features!
One of the new features we've included:
- Unlock new possibilities for text-to-speech audio. Use speech synthesis markup language (SSML) to adjust the speaking rate, modify pronunciation, emphasize words, add pauses, and more.
Launch the Articulate 360 desktop app on your computer to take advantage of this update, and click the Update button next to Storyline 360. You'll find our step-by-step instructions here.
Please let me know if you need additional help!

I tried using the above code and it seems to only work on one slide. What if I have single video animation on each slide. When I added the playback code on each slide, the Javascript does NOT work.
Also, how do you determine which video has which ID in the video array? Any help would be appreciated.

I developed some JavaScript-based code to control the speed of videos. In theory, this could work with audio, with some tweaking.
@Mark, would you be willing to share your code?
Thank you!
Hi Kathryn,
I have shared this code previously here, but here it is again,
The main thing to set: the variable numberOfVideos needs to be set to the maximum number of videos in your course. You only need to set this variable's value once — the default value. Once you've done this the code should work for all videos. And remember that you have to publish your course in order for the JavaScript to work; previewing won't make this work.
LaRonda, I hope these instructions will help you make your code work.
HTH,
Mark
Hi Mark, I Used your code, but this doesn't work in review 360 either in LMS like cloudscorm.
This just work when you run the story.html in the desktop.
Also, I preview in review 360 your storyline project and this doesn't work two.Link: https://360.articulate.com/review/content/9d2c369f-4418-4ece-8088-de6ac33be472/review
Do you have an extra solution for this?
Has there been any update on this?
Adding my voice to the users who would really like to see this functionality added to Articulate. This is pretty standard in most media players and definitely an expectation for many adult learners.Hi Kristi,
Thank you for checking in. Our feature roadmap is a great resource to see what we are currently working on. We aren’t ready to share a specific date on when this feature will ship, but we’ll be sure to update this discussion when it’s ready to go!
Thank you again for your feedback, and please don't hesitate to reach out to our support engineers if you need assistance on a specific project. We'll be happy to take a look!
This feature request to speed up audio/video was originally posted 8 years ago, with maybe hundreds of supporting comments. Why has nothing been done ever since? If not now, when? Or is it going to wait until my grandchild, yet unconceived, needs it?
Hi B Essien,
Thank you for reaching out! We appreciate your feedback.
Our latest release of Storyline 360 version 65 (Build 3.65.28121.0), includes the ability for learners to interact with videos via accessible controls that match the modern player style, exceed color contrast guidelines, and communicate perfectly with screen readers. Learners can change the playback speed, switch to full-screen mode, and use picture-in-picture mode to move videos to a floating window.
We are still tracking the feature request for the ability to adjust playback speed in order for audio can be consumed faster or slower. I've added your comments to the case and will be sure to update you on our progress!
+1, submitted feature request
YALL.
IT. IS. FINALLY. HAPPENING.
According to the Feature Roadmap, this is in development!
"Course Playback Speed Control - Let learners explore at their own pace by choosing a course playback speed between 0.25x and 2x."*happy dancing!*
It only took 9 years. First post in this thread was 11/20/2013. Neat.
