Story

The motto of this project is to provide a solution for the vocally challenged people to communicate as of like normal people. This methodology involves recognition of hand muscle movements accurately and integrates with the NXP FRDM K82F Board. The wearable-technology Myo Arm Band is used to recognize different hand motions based on the muscle movement. The electrical signals are produced according to the muscle movement in Myo Arm Band thus the signals will be transmitted to the NXP FRDM K82F Board accordingly. The NXP FRDM K82F Board, in turn plays the voice in consonance with the muscle movement which are previously stored in cloud/memory card. It contains different prerecorded voices for different gestures in its memory unit. The voice can be heard through the speaker/headphone which is connected to the NXP FRDM K82F Board and it can be understood by the normal people! Thus, the communication barrier, which is prevailing between vocally challenged people and normal people can be bridged!!
