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 lectu...
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!
Yes, everyone reading this, please make a feature request for variable speed of the timeline (and all of the audio, animations, video on it)! Thanks @Georg for the nudge.
This feature will allow learners to skim content that is more well-known and slow down content that is more complex. Also, humans can easily comprehend speech that is much faster than normal spoken rates:
"Most research has indicated no loss of comprehension or intelligibility at playback speeds of two or even three times normal speed. Cameron Earle, who is helping to commercialize variable-speed playback applications developed by Brigham Young University, said that most students chose rates that were 80 to 120 percent faster than normal with no decrease in test scores." (from the New York Times in 2003, bold added for emphasis; link: https://www.nytimes.com/2003/10/02/technology/now-hear-this-quickly.html)
As someone else said in this thread, this has also become an expected playback feature in the most common players, namely YouTube and Vimeo. Adding this feature will keep Storyline modern and help users engage better with learning.
