Methods and experiments for text-independent speaker recognition over telephone channels
H. Gish, M. Krasner, W. Russell, Jared J. Wolf · 2005
We consider methods for text-independent speaker identification that deal with the variability in the data introduced by unknown telephone channels. The methods investigated include probabilistic channel modeling, a channel-invariant model and a modified-Gaussian model. The methods are described and then evaluated with experiments conducted with a twenty speaker database of long distance telephone calls.
