Speech Recognition as a Support Service for Deaf and Hard of Hearing Students: Adaptation and Evaluation. Final Report to Spencer Foundation.
Stinson, Michael; Elliot, Lisa; McKee, Barbara; Coyne, Gina
This report discusses a project that adapted new automatic speech recognition (ASR) technology to provide real-time speech-to-text transcription as a support service for students who are deaf and hard of hearing (D/HH). In this system, as the teacher speaks, a hearing intermediary, or captionist, dictates into the speech recognition system in a computer that converts the dictated words of the teacher into print. The process of the captionist repeating the teacher's words is called shadowing. One purpose of the project was to adapt this process to ASR so that it could function successfully as a support service. The second purpose was to evaluate the effectiveness of the ASR system. This evaluation focused on the ability of 10 students who are D/HH to remember information presented with ASR and the perceptions of the students regarding the extent they could comprehend information that was presented with the ASR system. Results from the evaluation tentatively suggest that students did better on recall and recognition tests with an interpreted presentation than with the ASR presentation. Students also indicated that the lag-time, the need to wait for sentences to be displayed as text, interfered with, that is "bothered," comprehension. (CR)
