Schneier on Security: Speech-Activated Password Resets

Definitely interesting, and for the companies that I've been at, Mr. Schneier is right about the statistics. Phone calls into call centers are much, much more expensive per call than you'd think; $5-$30 a pop. So, when companies try and get you to use their web site, it's most often because of the cost.

Voice pattern recognition is interesting. Either you'd need either an exact match to a key pattern, which means that you'd have to have the same inflections, tonality, etc. within an acceptable range, or you'd need to have a large enough sample to make some judgement calls on the input code.

Could actually be interesting.
