F0 can tell us more : speaker verification using the long term distribution
Yuko Kinoshita, Shunichi Ishihara · University of Canberra Research Portal · 2010
This study explores some options for improving the performance of F0-based speaker verification. We tested different parameterisation techniques that enable us to capture non-unimodal distribution. We also tested the use of dynamic features (delta F0) and different scales (log10). As a result, we discovered that combinations of these techniques could significantly improve both the performance of speaker verification, and the reliability of the likelihood ratios.
