Recently submitted ICASSP paper - Weighted Median Fisher Discriminator and Linear-weighted Approaches to Limited Development Data PLDA Speaker Verification

posted Oct 10, 2014, 12:28 PM by Ahilan M.K
Recently, we studied the PLDA speaker verification system with limited microphone data, and we proposed the addition of a weighted median Fisher discriminator (WMFD) projection prior to length-normalised Gaussian probabilistic linear discriminant analysis (GPLDA) modelling. In combination with a linear-weighted approach to calculating cross-channel GPLDA parameters, WMFD-projected GPLDA extracts more reliable speaker discriminant information from limited development data, and provides a improvement over standard LDA-projected length-normalised GPLDA in interview-interview condition. These research outcomes were submitted to ICASSP 2015 conference.
