碩士 === 國立成功大學 === 電機工程學系 === 88 === Many people with multiple impairments need to use a powered wheelchair, voice output communication aid, environmental control, and access information technology. This thesis offers a concept of assistive technology device integration, based on a voice processor chip and a digital signal processor chip to fully integrated a speech recognition controller. The voice-controlled electric wheelchair combines a speech recognition controller with a general electric wheelchair. Using mode selector can make joystick commands and voice commands work together in the same system. Experimental results demonstrate that voice-controlled electric wheelchair can correctly execute voice commands in normal operation.
