Compensate the speech recognition delays for accurate speech-based cursor position control

Abstract

In this paper, we describe a back-compensate mechanism to improve the precision of speech-based cursor control. Using this mechanism we can control the cursor more easily to move to small on-screen targets during continuous direction-based navigation despite the processing delays associated with speech recognition. In comparison, using traditional speech-recognition systems, it is difficult to move the cursor precisely to a desired position because of the processing delays introduced by speech recognition. We also describe an experiment in which we evaluated the two alternative solutions, one using the traditional speech-based cursor control, and the other using the back-compensate mechanism. We present the encouraging evaluation results at the end of this paper and discuss future work. © 2009 Springer Berlin Heidelberg.
