Abstract:

Session variability in speaker recognition is a well recognized phenomena, but poorly understood largely due to a dearth of robust longitudinal data. The current study uses a large, long-term speaker database to quantify both speaker variability changes within a conversation and the impact of speaker variability changes over the long term 3 years. Results demonstrate the 1 change in accuracy over the course of a conversation is statistically very robust and 2 that the aging effort over three years is statistically negligible. Finally we demonstrate that voice change during the course of a conversation is, in large part, comparable across sessions.
