We demonstrate Parakeet – a continuous speech recognition system for mobile touch-screen devices. Parakeet’s interface is designed to make correcting errors easy on a handheld device while on the move. Users correct errors using a touch-screen to either select alternative words from a word confusion network or by typing on a predictive software keyboard. Our interface design was guided by computational experiments. We conducted a user study to validate our design. We found novices’ average text entry rate was 18WPM while seated indoors and 12 WPM while walking outdoors.
