Effects of GSM Speech on Text-Dependent Speaker Verification

Abstract

This paper investigates the effects of GSM speech on text-dependent speaker verification performance. An HMM-based system is implemented for performance evaluation. In order to match the real-world environments, the full-rate GSM speech database over cellular network is collected under different driving speeds. Experimental results obtained from different combinations of training and test conditions are presented, which provide more accurate results than previous works that used transcoded databases.
