A Principle Solution for Enroll-Test Mismatch in Speaker Recognition
A Principle Solution for Enroll-Test Mismatch in Speaker Recognition
Mismatch between enrollment and test conditions causes serious performance degradation on speaker recognition systems. This paper presents a statistics decomposition (SD) approach to solve this problem. This approach decomposes the PLDA score into three components that corresponding to enrollment, prediction and normalization respectively. Given that correct statistics are used in …
