Implementation of a Hybrid Voice Control
System for a Colony of Robots

Abstract: In this paper, a voice command system for autonomous robots is proposed as a project. The methodology adopted is based on hybrid techniques used in speech recognition which are zero crossing and extremes with dynamic time warping followed by a decision system based on independent methods test results. To implement the approach on a real time application, a personal computer interface was designed to control the movement of a set of robots by simple voice commands. The voice command system for four autonomous robots is designed. The main parts of the robots are a microcontroller from Microchip PIC16F84 and a radio frequency receiver module.
