The system estimated separately the eigenvoice and the eigenchannel before calculating the corresponding speaker and the channel factors. Finally, a channel-free speaker model was built to describe accurately a speaker using model compensation. The test results from the whispered speech databases obtained under eight different channels showed that the correct recognition rate of a recognition system based on JFA was higher than that of the Gaussian Mixture Model-Universal Background Model. In particular, the recognition rate in cellphone channel tests increased significantly.}, type={Artykuły / Articles}, title={Joint Factor Analysis of Channel Mismatch in Whispering Speaker Verification}, URL={http://journals.pan.pl/Content/101629/PDF/16_paper.pdf}, doi={10.2478/v10168-012-0065-9}, keywords={joint factor analysis, whisper, speaker verification.}, }
