making "Untraceable"-like calls
- by infoquad
In the movie Untraceable(http://www.imdb.com/title/tt0880578/), the killer(Joseph Cross as KillWithMe.com's webmaster) makes a telephone call with a computer and using some software(that convert's the actor's voice to female) fakes himself as a girl.
While the converting part may be technologically difficult to accomplish at this time, I wanted to ask whether it is possible to make calls with a computer, record the conversations and play an mp3 file so the other person hears it? How can this be done?
