[PDF][PDF] F0 can tell us more: speaker verification using the long term distribution
Y Kinoshita, S Ishihara - 2010 - assta.org
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.
