Voice Based Home Automation Using Tamil Language

Abstract

Speech Recognition is an inter-disciplinary sub field of computational linguistic that develops methodologies and technologies enables the recognition and translation of spoken language into text by computers. Speech recognition can be implemented by using the concepts of IOT.

Internet of things is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people are provided with unique identifiers and ability to transfer data over a network without requiring human-to-human, Main objective of this project is to design low cost voice recognition based home automation system for the physically challenged people to control the various home appliances in real time. This is possible by implementing the input using voice commands from the users. It provides a user-friendly interface for smart home automation system especially for disabled and elderly. Designing an embedded wireless controller system helps in enabling the control of automation.

The proposed system consists of a voice recognition module, Arduino Uno microcontroller, relay circuit. The speech recognizer is built for Tamil language. The data sets required for voice recognition are recorded and trained. These voice commands are tested to know the recognition rate of the speech recognizer to build a robust recognizer. Upon successful recognition of voice commands, Arduino drives the relay circuit. Hence, the home appliances are controlled by the regional language with the help of Arduino Uno microcontroller.
