Parakeet: A mobile speech recognition interface

Home > Software > Parakeet

Parakeet is a system for efficient mobile text entry using speech and a touch-screen interface. Users enter text into their mobile Linux device (such as the Nokia N800) by speaking into a Bluetooth microphone. The user then reviews and corrects the recognizer's output using an interface based on a word confusion network. We used PocketSphinx for the speech recognition.

Details about an initial stylus-based prototype of Parakeet can be found here. This research was funded in part by Nokia.
