- W2100083037 abstract "In this investigation, two probabilistic latent semantic analyses (PLSA)-based approaches are proposed for use in speaker verification systems to reduce the number of parameters required by prosodic speaker models to (1) estimate reliably speakers' bi-gram models and to (2) reduce the amount of required training and test data. The basic concept is to (1) adopt PLSA to smooth the underlying n-gram-based prosodic speaker models, and to (2) use PLSA to find a compact latent prosody space to represent efficiently the constellation of speakers. The proposed approaches are evaluated on the standard single-speaker detection task of the 2001 NIST Speaker Recognition Evaluation Corpus, where only one 2 minute training enrollment speech and 30 s test speech on average are available. Experimental results demonstrated that the proposed approach can reduce the required number of bi-gram parameters from 112 to 88 and 63 per speaker and improve the EERs of MAP-GMM and GMM+T-norm from 12.4% and 9.5% to 10.4% and 8.4%, respectively, and finally to 8.1% after fusing all systems" @default.
