ABSTRACT

Voice Based Home Automation is the project which uses Embedded System

technology. This project details the construction and building of a stand-alone trainable

speech recognition circuit that may be interfaced to controller just about anything

electrical, such as appliances, robots, test instruments, VCR¶s, TV¶s etc« Some of the

areas in which this system is used are Robotics and war appliances etc. The circuit is

programmed to record words which we want to recognize later. To control and command

an appliance(computer, VCR, TV security system etc.) by speaking to it, will make it

easier, while increasing the efficiency and effectiveness of working of that device and

reducing the manual mechanical work. At its most basic level speech recognition allows

the user to perform parallel tasks, i.e. hands and eyes are busy while continuing to work

with the computer appliance without interruption. This circuit allows one to experiment

with many facets of speech recognition technology.
