Abstract
A progressively general way to interrelate with machines is to simply talk to them. However, there is often an adjustment between easiness of use and system complexity. Thus, the main objective of this project is to design and implement a speech controlled wheelchair with speech recognition technology and execution of it by serial communication. For this purpose, a code is written on Arduino Uno and speech recognition is performed using easy vr 2.0, and then it commands to hardware circuit which connected to motors for its drive, Speech is a difficult and non-fixed signal produced as a result of numerous and difficult transformations, sound signal changes a lot due to many reasons so it is not possible to have 100% exact result, Result of our system are more than 80 per cent, The system as though looks surprising for disable people but we are hoping that this could be a small step for solving their everyday problems.
