As a result, variabilities arising due to gender, language and accent ( among many others) are suppressed. Inter-task fusion, in which such metadata information obtained from automatic systems is used, has been shown to improve speaker recognition performance. In this paper, we explore a Bayesian approach towards inter-task fusion. Speaker similarity score for a test recording is obtained by marginalizing the posterior probability of a speaker. Gender and language probabilities for the test audio are combined with speaker posteriors to obtain a final speaker score. The proposed approach is demonstrated for speaker verification and speaker identification tasks on the NIST SRE 2008 dataset. Relative improvements of up to 10\% and 8\% are obtained when fusing gender and language information, respectively.}, pdf = {https://publications.idiap.ch/attachments/papers/2019/Madikeri_ICASSP2019_2019.pdf} } crossreferenced publications: @TECHREPORT{Madikeri_Idiap-RR-07-2020, author = {Madikeri, Srikanth and Dey, Subhadeep and Motlicek, Petr}, projects = {SIIP}, month = {3}, title = {A BAYESIAN APPROACH TO INTER-TASK FUSION FOR SPEAKER RECOGNITION}, type = {Idiap-RR}, number = {Idiap-RR-07-2020}, year = {2020}, institution = {Idiap}, pdf = {https://publications.idiap.ch/attachments/reports/2018/Madikeri_Idiap-RR-07-2020.pdf} }
