Abstract

Speech recognition applications are becoming more and more useful nowadays. Speech recognition is the process of converting the frequency of sound and acoustic signal through the microphone to a sequence of texts. Humans have applied the function of the speech recognition into the computer systems and machine that can recognize the spoken words in the area of human-computer interaction. The final results of the recognized words can be used for the applications such as the control and commands, document preparation and also the data entry. Through the speech recognition, the applications and computers might be able to realize the instruction given and perform the output that we have designed. Speech recognition application can be used in different types of handheld devices and computers to perform the tasks in our daily life and it can be useful when come to some limitation like small screen devices or handheld controller. Speech recognition for smart home is a project which recognizes the spoken word by using the microphone and the home automation system can be fully operated based on the speech commands that we have designed and programmed. The project demonstrates a system that allows the control of the lights, fans, electronics doors and so on. The speech recognition system is uses programmable circuit of Arduino Uno microcontroller connected with the Visual Studio C# programming code interface to control the lights, motor of fan, servo motor as the door lock and use the motor to open and close the doors. The Microsoft Visual Studio, Visual C++, Visual C# and Arduino software (IDE) are used to design and modulate the programming and we have to test on the accuracy of the graph and improve the accuracy to the optimal level. In this project, the use of natural language - English as the interface for communicating voice input to interact with the system.
