Vlingo's interaction is mostly hands-free, but there are a lot of points where it really wants you to push a button or read the text on-screen. We've also found it's confusing for first time users who want to send text messages, while we've tried to make it almost impossible to mess up while using our app.

Small anecdote: I knew we were onto something when I got my mom a new Android phone for Christmas and she managed to send a text without a hiccup on her first try- she had never used voice tech or even a smartphone up to that point.
