Abstract: Device, language and environmental mismatch adversely affect speaker verification (SV) performance. We investigate such effects empirically based on the M3 (multibiometric, multilingual and multi-device) corpus (H. Meng et al., 2006). Device mismatch (among 3G phone, PocketPC and a desktop PC plug-in microphone) brings relative performance degradation of 523%; language mismatch (between English and Cantonese) brings 284% and environmental mismatch (between office environment and recording studio) brings 109%. In particular, verification with wide-band models on narrow-band test data outperforms narrow-band models on wide-band test data. The 3G phone's SV performance is generally low, but remains stable across environments. Additionally, durational variations within two-second utterances may cause a relative change of 633% in SV performance.
