Recently more & more hearing impaired people started using sign language. There are about 70 million people in the whole World that are not able to speak (dumb). A dumb person makes communication with other people using their motion of the hand or expressions. . Sign language helps the dumb people to make communication like normal people. The sign language translator which has been already developed uses a glove fitted with sensors that can interpret the 16 English letters in American Sign Language (ASL). Accelerometers and flex sensors are used in this system which increases its overall cost. We proposed a solution as a prototype called as “smart glove-for speech impaired people” which will translate sign language into text. It will help dump and deaf people to express their thoughts in more convenient way. As a sign language we have used traditional finger movements with contact switch wrapped around the user’s fingers. An IR transmitter receiver pair, HT12E and HT12D IC and, Arduino (Micro Controller) board helps transmitting data to PC. Moreover, use of contact switches reduces the system’s overall cost.
