Vocal sound help

[melontang]

Can anyone figure out/ does anyone know how on earth they made this vocal effect, or if it's a specific plugin, which one? You can hear Hyde speak, and about 5 seconds later it's played back amplified with a reverb buildup. I know how to reverse a clip, record the reverb and re-reverse it, but I just can't figure out how the heck they're doing it live, unless they're not.
