Abstract

Every human in this world need a safer home to make sure their lives not in the danger. That's why more application is been applying to the house to make sure a better home. Some of the application that add to make sure the house safer is automated window that will shut when raining is coming. For the door, voice recognition can be added to make sure nobody than the speaker can enter the room. Voice recognition is a method to make a system recognize the speaker identity. Such systems extract features from speech, model them and use them to recognize the person from his/her voice. Voice recognition is system that recognizing who is speaking and speech recognition is a system to recognizing what is being said. Generally these two terms are frequently confused and voice recognition is used as a synonym for speech recognition instead. The main contribute of this project is to recognize the speaker voice and activate the motor that represent any application that can be apply. Matlab (Mathematics Laboratory) will be use to recognize and analyze the people's voice and if the voice wave match the sample in the template, the control circuit, PIC microcontroller circuit, will activate the motor. This project has great potential since everybody need a comfortable house. This project is start by researching the simple voice recognition that available in open source. After getting the system that suitable with the project, learning session will be start before building and testing the system. In the same time, the PIC motor controller also will be build. The PIC system is not a very difficult to build as the information is easy to get in internet, book and journal. But for the for the voice recognition it is a little bit hard to create the system although there is some application or past studies about it. The objective of the project is to show the simulation the motor movement via voice command. But in the end, only the PIC motor controller and voice recognition is been complete. The serial connection between PIC and voice recognition system is been unable to comply because of some problem that cannot be avoided. This system is start form transferring a human voice which in an analog into the computer to change it into a digital. The wave is been receive by the microphone and than it will transmit it to the Matlab. The wave will be go through some signal processing where the wave will be change from analog signal it into a digital signal. After the signal is been process, the wave that been recorded will be train in Matlab by using Neural Network. This step is to create a template that will be use for the testing the system afterwards. The PIC motor controller is being use to represent any application that can be used for this system. This project indeed is a very interesting and challenging project in many aspects based on the stated objectives and presented information. Although facing some problem, but I'm manage to fmish this project. The system can make a different between the two words that been recorded, process and train inside the Matlab. The PIC motor controller is also working very well.
