Voice Operated Induction Motor Speed Control Through RF Communication

Abstract

This project deals with system operations using voice recognition. The user can operate a DC motor through voice commands. Using wireless. The user has to first train the device with some standard words to recognize his own voice. The kit will understand the user’s voice and commands. The voice commend is transmit via RF. The RF receiver connected in micro controller kit. During execution, the user can do the operations using pre defined voice commands like ‘Forward’, ‘Reverse’, ‘Speed up’, ‘Speed down’ etc. If any un authorized persons try to execute, the device does not respond. This project is secure so that un authorized users cannot do any operations using their voice commands. The main part of the project is Microcontroller PIC16F73.
