Abstract
Interactive Voice Response System (IVRS) is an automated system which is multi-lingual and makes use of text-to-speech (TTS) technology. This paper describes the implementation of an Interactive Voice Response System personalized especially for students to obtain any information desired by them in a reliable and timely manner by just placing a normal call, thus being a building block of a smart city. It works on a 24/7 basis and is very user friendly. The IVRS system comprises of ring detector hardware, dual tone multi frequency decoder (DTMFD), microcontroller, serial interface unit, computer and cell phone. It includes a ring detector hardware which identifies the caller and connects the identified caller to a computer. When a caller presses a key from their cell phone the input is produced in the form of dual tone multi frequency signal. The computer generates voice response dynamically based on the key pressed by the caller. A Text to Speech Converter converts the database into a voice format as per the response given by the caller.
