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!
I haven't had the chance to see if this will work in Storyline, but can javascript be used for the same purpose as shown here for Captivate? https://www.youtube.com/watch?v=eSgwS7DeMKo
Although this is only a solution for embedded videos and not the module itself. I'd like the player to have playback speed options. That would be an awesome feature.
Has anyone tried adding JavaScript to Storyline to adjust the playback speed??
You could probably use javascript to find the <audio> tag.
//this line of code will return an array of all audio tags on the HTML page
var x = document.getElementsByTagName('audio');In theory, the page probably will only have one tag so your audio should be the first item in the array. You can now assign the audio an id.
//this line of code assigns an ID to the first element in the audio array
x[0].id='testAudio';Now that you have an ID, you can find the audio by ID at anytime and manipulate the playback rate.
//this code speeds up playback to 125% speed
testAudio.playbackRate=1.25;//this code cuts the playback speed to 50%
testAudio.playbackRate=.50;
