Matt Cutts of Google recently released a video on the Google Mobile App which uses voice recognition to return Google search results. The application is available for iPhone, BlackBerry, Windows Mobile, Nokia S60 and Android phones. The voice recognition system appears to work very well for Matt in the video below. Most voice recognition systems have been frustrating to say the least. I know I have had my fair share of frustration with the 1-800-GOOG-411 phone system.
