Usage, Performance, and Satisfaction Outcomes for Experienced Users of Automatic Speech Recognition
By Koester, Heidi Horstmann, PhD; Journal of Rehabilitation Research and Development, Vol. 41, No. 5, pp. 739-754Publication Date: September/October 2004
Paper presents outcomes data from 24 people who use automatic speech recognition (ASR) as their primary means of computer access. In-person survey interviews were conducted to assess ASR usage and satisfaction. Among participants who had a choice of computer input methods, 48 percent reported using ASR for 25 percent or less of their computer activities, while 37 percent used ASR for more than half of their computer tasks. The participants indicated that that their satisfaction with ASR was just above neutral, as it averaged 63 out of 100. The most frequently cited reason for using ASR was to reduce upper-limb pain and fatigue. User performance was measured among the participants as they performed a series of word processing and operating system tasks with their ASR systems. Quantitative results indicated that users who had the best performances tended to employ efficient correction strategies while using ASR. The author contends that ASR systems have the potential to greatly improve productivity and comfort during computer tasks for a wide variety of computer users.
