Can I slow down the audio voice selected in Storyline 360?

I am using one of the audio voice pre-loaded in Storyline 360 and it seems they are all speaking very fast.  Is there a way to slow their speech?

    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:

    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!

You're missing the point.  We - the author - want to manage the speed as we GENERATE the speech from text!  WE want to dictate the speed as it's created, NOT adjust it at the user end (the player side)!   A better text-to-speech engine is what we want - one with the ability to apply emphasis, etc.

this should be ease, storyline uses - as far as I know* - Amazon Polly for text to speech

and here is the function to change the speed (for the articulate developer)

https://docs.aws.amazon.com/polly/latest/dg/voice-speed-vip.html

Two speed options are available to you when using SSML with Amazon Polly:
  • Preset speeds: x-slow, slow, medium, fast, and x-fast. In these cases, the speed of each option is approximate, depending on your preferred voice. The medium option is the normal speed of the voice.
  • n% of speech rate: any percentage of the speech rate, between 20% and 200% can be used. In these cases, you can choose exactly the speed you want. However, the actual speed of the voice is approximate, depending on the voice you've chosen. 100% is considered to be the normal speed of the voice.

* TCP Connection: Storyline.exe <-> Articulate 360 Desktop Service <-> Amazon Cloudfront
