This paper examines the linear relation between Shifted Delta Cepstral (SDC) features and the dynamic of prosodic features. SDC features were reported to produce superior performance to ˘ features in Language Identification and speaker recognition systems. A selection of more correlated SDC features is used in speaker verification to evaluate its robustness to channel/ handset mismatch. The experiment reflects superior performance of selected SDC features regarding to features in speaker verification using speech samples from NIST 2001 Ahumada database.

Index Terms: speaker verification, shifted delta cepstral, prosodic features, channel mismatch.
