As the name suggests, the Interactive Voice Response (IVR) system is a bridge for interaction between the information seeker and information giver. The Information seeker has to have a telephone from wherein he has to dial a specified number from anywhere at any time of the day; after dialing the number and establishing the connection, he has to follow the online instructions to access the information that he may seek from the prerecorded voice responses that are stored in the computer database based on his choice of inputs as required. The caller can seek the desired information by feeding input to the IVR system through either touch pad of his telephone or through Dual Tone Multi-Frequency (DTMF) signal. The input can be chosen from the list of information stored as per the subject which is played through pre-recorded voice messages. Through the application of the IVR system, the service provider can dissipate the information for the frequently asked question /answers at any time without interruption, which is very economical in terms of cost, time and energy. This is very efficient system which can replace an operator with a machine enabled with artificial intelligence. The IVRS system can be designed with very easily available electronic components like microcontroller and some basic electronic chips that are customized with a computer, with homemade software running in the back office while the other dynamic works can be handled on the front end. Now-a-days every institution needs automation. As a part of college automation, we have to do a project Interactive voice response system for college Automation. Our project allows the user to know our institutions overall information quickly through the telephone line without the intention of the college authority. In the hardware side embedded system has been used. This microcontroller controls the whole hardware. Mobile line is used for communication purpose. Embedded C has been used for frontend software programming. Overall information about the institution is presented and made reachable to the users by our project. It will be very helpful to the users to be acquainted with institutions information without having to spend time with the institutions authority thus saving time and resources at both ends.
