This sort of thing often doesn't work for me because, well,<p>hmmm.<p>Because I have to pause in the middle of a sentence sometimes to, ah,<p>um<p>. . . gather my thoughts.<p>I'm looking forward to when the AI is smart enough to know that I'm just a slow speaker when I'm using voice search or whatever.
Also, I started to work on a full Voice Activity Detection algorithm that will work client side. I can't wait to see it live and get user feedback!
