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!
It looks like Articulate are using Amazon Poly for the text-to-speech, and it allows the use of SSML tags.

It looks like SSML is a W3C standard whereas VTML is a proprietary standard so my preference would be to support the former; especially since it seems to already be supported by AWS.
Could the prosody tag be permitted within Storyline to control speed?
I wanted to try the SSML tags you mentioned so I added the 'prosody' tag just like in the AWS link you shared but the TTS in Storyline just reads it as regular text. But I wasn't aware of SSML or Amazon Polly before now so thanks for sharing that info.
