Voice Authentication Trips Up the Experts
by Anne Eisenberg

    Some snippets:

    Computer-based applications of speaker recognition are gradually
expanding, and already include intelligence gathering and telephone
transactions, in which sellers reduce the risk of fraud by making sure
that the voice on the line is in fact that of the credit card's
owner. ... Some of the researchers say they are finding the task
harder than they had expected.  ...  accuracy has been hampered by
many difficulties, from the differences in telephone connections and
microphones to the inherent variability of the human voice. "Voice
characteristics vary with your age, your metabolic state, your
emotional state and all the ways you can say 'yeah,' " Dr. Doddington
said.
