Cluster-Dependent Feature Transformation for Telephone-Based Speaker Verification
Chi-Leung Tsang, Man‐Wai Mak, Sun Yuan Kung · 2003
This paper presents a cluster-based feature transformation technique for telephone-based speaker verification when labels of the handset types are not available during the training phase. The technique combines a cluster selector with cluster-dependent feature transformations to reduce the acoustic mismatches among different handsets. Specifically, a...
