Introduction

The project “Attendance through Voice Recognition” is a tool that can help an organization or academic institute to have attendance of their employee or students and also the faculty members.It also record the time and date at which the member is present.
This project allows a organization or academic institute to overcome the problem of proxy to a great extend.
Many organization is facing the problem of proxy. Employee may mark their attendance by some other guy and the organization may not detect it because there is no such process of verification and it is difficult to recognize the face or voice of every person.
The same situation is their in academic institute also.
The faculty member may mark their attendance though they are late or absent from the institute by some other colleagues which is a common scenario in a government institute.
The faculty members can also get help from this software by detecting proxy of students also.

The Project actually describes the process behind implementing a voice recognition algorithm in MATLAB. The algorithm utilizes the Discrete Fourier Transform in order to compare the frequency spectra of two voices. Chebyshev’s Inequality is then used to determine (with reasonable certainty) whether two voices came from the same person or not.
If the two voices matches each other than a present is marked in the attandence register i.e in a database and with that present, the date and time of attendance is also stored.

Initial Problem

Speech is a natural mode of communication for people. We learn all the relevant skills during early childhood, without instruction, and we continue to rely on speech communication throughout our lives. It comes so naturally to us that we don't
