Speech-controlled vehicle for manufacturing operation

This paper proposes a speech-control vehicle that can be operated in manufacturing line. The aim of the study is to recognize user's voice using speech recognition method for remotely controlling the movement of operating vehicle based on user's command. This project can be divided into two parts; development of android application and hardware implementation. Android application is developed to integrate the speech recognition technique in android smart phone with the controller. Hardware implementation involves construction of a prototype vehicle equipped with DC motor, motor driver, Bluetooth module, Arduino microcontroller and power supply unit. A set of data collection for voice command is analyzed to evaluate the accuracy of the speech recognition method. Result suggests the projection of command with clear and strong voice offers higher accuracy in providing a set of viable commands to the operating vehicle.
