We all know that it's dangerous to text on a cellphone while driving. Study after study proves it, and everyone from carmakers to cellphone companies is clamoring not to do it. New Hampshire and Rhode Island are among the latest states to outlaw the practice, and AAA and Verizon, among others, are calling for a national ban.

Fortunately, budding technologies are offering another solution. Products abound that enable drivers to speak aloud a text or e-mail message, or listen to one being read, without having to type on their phones. With speech-recognition or "voice-to-text" technology, drivers can keep their eyes on the road.
