Telephone Voice Changers/Disguisers?

I read a supposedly factual account on a Angelfire page awhile back about a California woman who met a East Coast guy online and fell in love with him…

After about a year of online romantic mush, they progressed to talking on the phone for another year. Then they were supposedly to finally meet in person, but the guy was a no show, and when the woman tried to contact him, he had disappeared. After some amateur detective work, the woman finally found out that the guy was actually a woman and had been using a voice changer/disguiser during their numerous phone calls.

The question is: do these devices actually work so well that a person would be consistently fooled over the course of a year?

One five minute phone call is believable, but wouldn’t there be enough anomilies and flaws in the masking process that would be evident through the course of hours of discussion?

>but wouldn’t there be enough anomilies and flaws in the >masking process that would be evident through the course of >hours of discussion?

One sentence would probably suffice. Hours of discussions are implausible.

There are some very good electronic voice disguisers out there that would fool most people, especially if you weren’t expecting a trap. I believe that Phil Hedrie, the radio DJ prankster, uses them and fools many, many unsuspecting listeners.

I just find it incredibly absurd that a woman could disguise her voice as a man’s and go undetected for an entire year.

I’m sure a expert sound engineer could do something like that, but a consumer gadget?
