A qualitative approach was implemented over the course of two semesters, Fall 2003 and Spring 2004, to: (a) ascertain students’ perspectives on speech recognition, and (b) understand how students used speech recognition programs as a tool to meet the academic demands of postsecondary education. Data collection for this study included interviews, participant observations, field notes, videotape, and course assignments. This study provided qualitative data regarding an assistive technology tool that has traditionally been studied within a quantitative paradigm. Environment, individual characteristics, and life demands were found to impact student use of their speech recognition program. Implications for users, educational professionals, and researchers are presented in the final chapter of this paper. Reproduced with permission of the copyright owner.
