Speaker verification in mismatch training and testing conditions
Marcos Faúndez-Zanu, Adam Slupinski · 2000
This paper presents an exhaustive study about the robustness of several parameterizations, with a new database specially acquired for the purpose of a speaker recognition application.This database includes the following variations: different recording sessions (including telephonic and microphonic recordings), recording rooms, and languages (it has been obtained from a bilingual set of speakers).This study has been performed with covariance matrices in a text independent speaker verification application.It reveals that the combination of several parameterizations can improve the robustness in all the scenarios.
