title: User performance with speech recognition: a literature review.
abstract: The application of speech recognition to the computer access needs of people with disabilities continues to grow, and a greater understanding of user performance with such systems is needed. This article reviews what is known about user performance with speech recognition systems, with a focus on its application to accommodation of physical disability. Although current systems offer the potential of text entry at 150 words per minute, the literature suggests that users actually achieve somewhere between 8 and 30 words per minute. Barriers that may contribute to this gap, such as the costs associated with correcting recognition errors, are reviewed, and directions for future research are proposed. A major need is for additional research involving users who have physical disabilities.
