Speech Recognized Automation System Using Speaker Identification through Wireless Communication

Abstract

This paper discusses the methodology for a project named Recognized Automation System using Speaker Identification through wireless communication. This project gives the design of Automation system using wireless communication and speaker recognition using Matlab code. Straightforward programming interface of Matlab makes it an ideal tool for speech analysis in project. This automation system is useful for home appliances as well as in industry. This paper discusses the overall design of a wireless automation system which is built and implemented. The speech recognition centers on recognition of speech commands stored in data base of Matlab and it is matched with incoming voice command of speaker. Mel Frequency Cepstral Coefficient (MFCC) algorithm is used to recognize the speech of speaker and to extract features of speech. It uses low-power RF ZigBee transceiver wireless communication modules which are relatively cheap. This automation system is intended to control lights, fans and other electrical appliances in a home or office using speech commands like Light, Fan etc. Further, if security is not big issue then Speech processor is used to control the appliances without speaker identification.
