Speech Dasher is a novel text entry interface in which users first speak their desired text and then use the zooming interface Dasher to confirm and correct the recognition result. After several hours of practice, users wrote using Speech Dasher at 40 (corrected) words per minute. They did this using only speech and the direction of their gaze (obtained via an eye tracker). Despite an initial recognition word error rate of 22%, users corrected virtually all recognition errors.
