The latest version of Adobe XD introduces voice prototyping and a UI kit for Amazon's recently introduced Alexa Presentation Language.

Adobe's new Experience Designer (XD) aims to simplify and consolidate the mash-up of design and prototyping tools currently used by most User Experience designers.

Maybe you have a UI kit of a bunch of off-the-shelf components. You can start the same with XD. If you know how to use Keynote, you’ll pick up XD immediately.
