Robust Speaker Recognition Biometric System a Detailed Review

his paper reviews Biometric based Speaker Recognition and presents brief about various algorithms and techniques used at various stages of Speaker Recognition and development of Attendance System as application of Speaker Recognition. The research is being carried out in this area for many years. However, the accuracy of system depends upon speaker’s variability and environmental conditions. Various stages of speaker recognition include Pre processing of a signal, Feature extraction, Normalization, Post-processing, Classification or Modelling and Decision making. The main aim of this paper is to discuss and compare different approaches of different stages with main emphasis on robustness in noisy environment.
