Text to speech speed
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 recently created an application that might address your need of adjusting the speed for Text to Speech in Storyline. It’s a bit of a workaround though as you’ll have to go to the source that Storyline uses, Amazon Polly voices.
Here’s what you do:
- Get an Amazon Polly account (yes, there is some cost involved but doesn’t seem that prohibitive) (https://aws.amazon.com/polly/)
- Save your scripts as separate files (MS-Word or Text)
- Download HeroVoice TTS from the Microsoft Windows Store (fully functioning 15-day free trial)
- Encode your files with HeroVoice TTS – apply a global setting for speed and even comma duration so your files are consistent.
- Select the voice you want – these are the same as you’ll find in Storyline today including Neural voices (which aren’t currently available in Storyline)
- Load each audio file into Storyline
If you want to have even more control, you can also use SSML tags for creating more nuanced text to speech.
