Siri is a startup that utilizes speech-to-text and searches for what you want it to through voice commands. They call it a virtual personal assistant (VPA). The company raised $15.5 million in its second round of funding from Menlo Ventures and Morgenthaler Ventures.

For example you could tell the device that you want to see a movie and it will find tickets prices and showtimes. Or you can call a cab when you are out of town. Previously Siri raised $8.5 million in funding. The company has not officially launched its product yet.
