Evaluation of Lineal Relation between Shifted DeltaCepstral Features and Prosodic Features in Speaker Verification

摘要

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 A features in Language Identification and Speaker Recognition. 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 A features in speaker verification using speech samples from NIST 2001 Ahumada database.
