Аннотация

This paper presents design, implementation and validation of a PC based Prototype speaker recognition and verification system. This system is organized to receive speech signal, find the features of speech signal, and recognize and verify a person using voice as the biometric. The system is implemented to capture the speech signal from microphone and to compare it with the stored data base using filter-bank based closed-set speaker verification system. At first, the identification of the voice signals is done using an algorithm developed in MATLAB. Next, a PC based prototype system is developed and is validated in real time. Several tests were made on different sets of voice signals, and measured the performance and the speed of the proposed system in real environment. The result confirmed the use of proposed system for various real time applications.
