Plug in your headphones to get better accuracy for voice commands, and better sound quality for your ears. You still get all the heads-up and hands-off benefits of Talkler. But you also get privacy and high-def sound.
Plus, standard headphones have controls on the cord, which you can use to play to the next or previous email. Just double-click or triple-click the button on the cord, as you might to control your tunes.
