Technology is serving the mankind with the ripen fruits of its advancement; similar is the objective of our paper to aid to mankind with ease of initiating a task with advancement in technology as the main weapon to reduce the complexity of the tasks in hand. In this paper we have developed an algorithm for playing the desired track by just calling out the name of the latter. Cross correlation has aided us in making this algorithm; all of our work is done by using MATLAB. Basic transducers are used to provide the physicality to our work.
