The Perception Of Natural, Cell Phone, And Computer-Synthesized Speech During The Performance Of Simultaneous Visual-Motor Tasks, Nirmal Kumar Srinivasan

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study investigated the influence of top-down and bottom-up information on speech perception in complex listening environments. Specifically, the effects of listening to different types of processed speech were examined on intelligibility and on simultaneous visual-motor performance. The goal was to extend the generalizability of results in speech perception to environments outside of the laboratory. The effect of bottom-up information was evaluated with natural, cell phone and synthetic speech. The effect of simultaneous tasks was evaluated with concurrent visual-motor and memory tasks. Earlier works on the perception of speech during simultaneous visual-motor tasks have shown inconsistent results (Choi, 2004; Strayer …
