Variable Audio Speed Options?

A client has requested a feature that would involve learners being able to change the playback speed of the audio narration on either a per-slide basis or for the course module overall. For example, being able to select different audio speeds from a drop-down menu (perhaps at 1x, 2x, 3x speed options). Is this possible to set up in Captivate?

It's worth mentioning that the type of audio (neospeech captivate voices vs. narration by a real human) has not yet been deliberated upon. I know that there are ways to control the text-to-speech audio speeds using vtml tags, but I'm looking for something that a learner could potentially interact with and use to progress through the module at their own pace.

Note: I am building a responsive project using Captivate 2019
