Today, Internet is the best place to communicate and share information among the people throughout the world and gives an endless support of knowledge and entertainment. The main objective of Internet technology is to increase efficiency and decrease human effort. With the introduction of Internet of Things (IoT) in the last decade, we have been pushing for ubiquitous computing in all spheres of life. Physically challenged people are also using the Internet with the help of Speech commands (SC). The main objective of this paper is to minimize the effort and increase efficiency of the Voice recognition and IoT based secured automation, To design multi parameter monitoring system using Microcontroller that measures and controls various global parameters and the system comprises with wireless mode of communication. These processes were managed using Arduino and Bluetooth. The parameters that can be tracked are temperature, humidity and fire. Here we design the automatic system for voice based industrial automated system. That is an android app is used to give input data as voice input to the micro controller. In the micro controller section there will be a Bluetooth module to receive the data transmitted. Once the data is received the coding is executed according to the data which the controller got. Here we can monitor the temperature, humidity and gas and fire value of the industry and according to the values the prevention action is taken. The motor, dc fan and the light is turned on and off according to the voice input. And the action done here is implemented to the IOT.
