Abstract :
This paper aims at speaker verification system for Cellular phone transmission for high security purpose. Online processing of voices and verification is achieved in this. Various measures were taken to improve the SNR of the incoming cellular channel signal, as otherwise it would lead to very high degradation in verification performance. A verification percentage of 88.18% is achieved and imposter acceptance is 1.89% when voices are recorded online and tested on continuous sentences.
