That looks really interesting. You should make it clearer that you don't actually handle voice recognition. When I read: "Developers use Wit to easily build a voice interface for their app." I expect you to handle things from start to finish. Also, let me try it! It's frustrating because the UI looks like you can experiment but it's only an animated demo (or am I missing something??) In particular the mic logo is use…
You're right, we'll make it more clear on the landing page. A full out-of-the-box integration with some voice recognition engines (we love CMU Sphinx, open source) is in our roadmap.
> Also, let me try it!
We purposely didn't provide a "end-user" demo (something that would look like chatting with Siri) because we want to focus first on the developer experience, when they configure Wit to understand their very own end-users intents. You can require an invite and try this in less than 5 minutes.
