Great idea and I like the minimalist design. A live demo would make wonders to your conversion rates (or did I miss the link to it?). e.g. I would not pay before I hear the quality of the TTS. Also the "(We'll bill every $5 in usage)" is confusing, and made hesitate before clicking the Get Started button. Put a pricing page, not under your call for action, it's needless excessive information that just will lower your click through rates IMHO. Solid idea, but you can improve the landing page significantly in my opinion.
