Do you know how to adjust speed of audio created by "Text to Speech"?

Hi Kelly,

Thank you for your help.
Is it possible to change the entire speaking speed?（like 0.75x speed)

Hi, Akiko.

While not a current feature of Storyline, we have a request logged for the ability to slow down/speed up the pace of text-to-speech voices, and it's linked to this discussion.

We'll come back to update you when we have news to share. 

Hi, Maria

Thank you for your help.

I hope that feature will be implemented soon.

I see that the request has been logged but just wanted to drop a comment so I get a notification when you update and to say that I also hope this feature is added soon!!

I rememember selecting the playback speed in the past from somewhere inside storyline? Is this something that gets selected once and can not be adjusted ?

Hi Philip!

You can adjust the playback speed of your videos by hovering over the playback speed icon to choose any speed between 0.25x and 2x. Please let me know if you have additional questions! I'll be happy to help.

I agree that the text to speech speed needs to be adjustable. We use the text to speech for our reviews before doing voiceover work but the speed is too fast. This creates the need to realign the slide elements once voice over work is done. If individual designers could select a speed (as others suggested 1-10) that closely matches their narration speed it would greatly improve this product and be a big time saver.

I see comments from over 4 years ago that this was being tracked and an idea for future improvement. Is there any update on when that could happen?

Hi Jonathan, 

We don't have any new updates to share regarding this feature request, but you can check out which features are being worked on here in our feature roadmap. Here's a quick look at how feature requests are handled for your reference. 

Adding my vote for this feature.

Hi all, adding feedback from a global corporation too: it needs to be possible to slow the voice over down. Adding pauses is not helping... There are even special cases we had the text-to-speech voicing "comma" and other punctuation. But it's getting better and we adopted "Mathew" as one of the team, as he sometimes even sounds human :) Hope this will move up on the roadmap.

Hi Barbora,

I appreciate you taking the time to share what you’d like to see in Storyline 360 and I'll be sure to share your comments with my team!

Is adjusting the overall speed of the text-to-speech audio possible now that neural text-to-speech audio is available in Storyline?

Hi Lori!

I'd be happy to share some insight on this!

We currently have a feature request logged for the ability to slow down/speed up the pace of text-to-speech voices. This feature is separate from the Neural Text-to-Speech feature we just released in Storyline 360 version 3.80.30988.0.

I'll go ahead and include your voice in the feature report, and will update this discussion if it makes it onto our Feature Roadmap!

+1 for the option to adjust text-to-speech generated audio speed.

Also, please add more human-like voice options - right now, seems only "Matthew" somewhat sounds human.  We DO love Storyline's text-to-speech feature, which streamlines our course development process with the Closed Caption (a mandatory for us) capability as easy as a checkbox built into the workflow.  (My team has used other text-to-speech tools that generate more natural human voices. However, Storyline's ability to do all of these at the same time is definitely a winner!)

Please make it better. Thanks!

Hi Mengqiao!

Thanks for reaching out and sharing the feedback!

I'll include your comments in the feature report our development team is currently tracking. We'll be sure to notify you as soon as we have updates to share!

Have a great rest of your week!

Add another request to adjust the speed in the text to speech function. It's a lifesaver in its current form but it simply too fast for most training assets I work in.

Hi there Tzipora, 

Thanks so much for reaching out! 

I've included your voice in this feature request. We'll be sure to update this thread in the future with any news or updates. 

Hope that you have a great day and happy developing! ✨

+1 for the ability to control text-to-speech speed! Thank you!

Yes, pleas add: the ability to control text-to-speech speed. I received a request today from a couple of people asking is there a way if there is a voiceover can they control the speed? While their listening to the education?

Export audio to adobe premiere pro then adjust speed in that and reimport to articulate.

I agree this needs speed control. Pauses are not good enough. Even captivate can do this. https://iconlogic.blogs.com/weblog/2015/03/adobe-captivate-slow-down-your-speech-agent.html

Hi James!

Thanks for reaching out and sharing that tip!

I've also included you in the open feature request: More editing tools for Text-to-Speech. We'll update this discussion as soon as we have news to share.

Adding another +1 to have the ability to slow the speech down with text-to-speech. I love the new neural voices and updates but would love the ability to adjust the speed of the speech. I have customer asking me to slow down the audio and unfortunately, I am unable to.

Hi Mike! 

Thanks so much for sharing your thoughts with us. 

I've included your voice in this feature request. We'll be sure to update this thread in the future with any news or updates. 

Have a great start to your day! 🎉
