The Coming Wave of Gadgets That Listen and Obey – New York Times Vlingo’s service lets people talk naturally, rather than making them use a limited number of set phrases. Dave Grannan, the company’s chief executive, demonstrated the Vlingo Find application by asking his phone for a song by Mississippi John Hurt (try typing that with your thumbs), for the location of a local bakery and for a Web search for a consumer product. It was all fast and efficient. Vlingo is designed to adapt to the voice of its primary user, but I was also able to use Mr. Grannan’s phone to find an address.
