Slow down computer voice audio narration in Storyline 360?

Hi there, Michele. Your best bet would be to use an audio editing tool.  The audio editor in Storyline can do quite a few things, but that level of editing isn't supported.

We're tracking requests for more editing capabilities with text-to-speech, so I'll add this discussion.  That way we can keep you updated!

Adobe Audition can do a creditable job of slowing down a narration track. That's how I usually do it if I narrate something and there is a passage where I speak too fast.

Cheers!

If you don't have a program (and/or money) Audacity is a great free product.

Thanks everyone! I do use Audacity so will export/import/tweak/import again.  Thanks for adding this discussion, Crystal. It will be a helpful feature. 

Have a good day, Michele

I am the late comer on this discussion.  What is the latest status?  It has been 3 years since the most recent post on slowing down our text to speech colleagues.  I am hoping for improvement.  We have audience whose native language is not English.  The speed poses additional challenges in their learning process.  The demo speech is quite normal.  However, the speech over the text was very fast.

Hi, KC.

Thank you for reaching out!

We have a couple of similar requests, so I want to make sure I add your name to the correct one. The original post in this discussion asks for the author's ability to slow down the text-to-speech audio. We also have a feature request logged to allow learners to slow down or speed up the audio. 

I'm happy to add your voice to either (or both) those requests!

This feature is needed. I've noticed on my newest computer, the narration speed has increased and is hard to understand due to how fast the narration goes. Having an incremental speed adjustment (global would be awesome) on computer narration is needed.
