Alternative Voice Communication Device using Eye Blink Detection for People with Speech Disorders

Abstract

Speech disorders is an inability to articulate sound due to medical ailments such as brain damage, stroke to paralysis and several other diseases. Research data suggests that about 15 million people in the world have partial or complete impairment of language expression due to brain damage, mostly from stroke. In this work a low-cost speech assistant device is proposed an alternate augmentative communication device for stroke or paralyzed patients. The eye blink sensor is used as the primary sensor for detection of eye blink. Based on the eye blink gestures the common words are displayed in the LCD and these words are also converted as voice output. This prototype will be an alternate communication aid for people with speech disorders.
