Parakeet: A Demonstration of Speech Recognition on a Mobile Touch-Screen Device

IUI '09: Proceedings of the ACM International Conference on Intelligent User Interfaces, 2009.

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 entered text at 18 WPM while seated indoors and 13 WPM while walking outdoors.
