There are some UI issues from what I noticed:

At small breakpoints, the UI (especially the "try it now" button) can overlap some text. Sizing also seems off.

Another issue I noticed is the play button itself, the entire circle area is clickable, however only the play/pause icon can actually be clicked.

There are also numerous accessibility issues. If you're going to advertise this as something to improve accessibility, it might be good to actually concentrate on that for your landing page.

I do hope the UI can be improved, as the product looks solid.
