Abandonment of Speech Recognition by New Users
By Koester, Heidi Horstmann; RESNA 26th International Annual Conference 2003,Publication Date: 2003
Three-year longitudinal study conducted to gain understanding of how well automatic speech recognition (ASR) system meets the needs of people with disabilities. Eight people participated in the study. Seven of the participants used Dragon NaturallySpeaking, while one used Dragon Dictate. Text entry rate and recognition accuracy were evaluated using the QuickMAP procedure, which was developed for the study. The procedure consisted of transcribing a short paragraph using ASR in each of two phases: (1) a dictation phase, and (2) a correction phase. The main purpose of the dictation phase was to measure the clients’ recognition accuracy, while the correction phase allowed for measurement of the clients’ true text entry rate, as the time required to correct recognition errors was taken into account. Relatively poor and variable performance, in terms of recognition accuracy and text entry rate, appeared to be a predictor of the high rate of client abandonment. When participants didn’t experience rapid improvement and short-term benefits from their ASR system, they were more likely to abandon the technology. The authors contend that further research is necessary to learn more about methods to facilitate positive outcomes with speech recognition technology.
