Effect of GSM System on Text-Independent Speaker Recognition Performance
S. Abdel Kader · 2008
This paper introduces the influence of GSM encoder/decoder on text independent speaker recognition performance based on Vector Quantization (VQ) classifiers. A database consisting of 136 speakers is used to investigate the system performance. The speaker recognition is evaluated using the original database. The speech files are then passed through the GSM coder/decoder. The coded speech is finally used for training and testing the speaker recognition system. The effect of the additive white Gaussian noise (AWGN) and Rayleigh fading channels on the system performance is also investigated.
