it used to be military, then commercial, now widespread (to the individual).
in early 2000's we used voice print authentication for a commercial
directory assistance service. "hello, infone" all it needed to give
confidence sufficient to authorize for charges.
(the margin of error, of course, tune-able to desired tolerances, and
indeed, this is where the bulk of complexity lies - too tight, and you
can't auth from a pay phone or noisy cell call. too loose, and the
number of false positives skyrockets...)

Cheney's pacemaker had the wireless capabilities removed, specifically
because of this risk, which at the time was under-appreciated by the
public. (recent medical device hacking research at security
conferences has raised the public awareness :)
