Lipsyncing sound

Alright heres my problem, Im trying to lipsynch a flash movie with a sound file, but every time that I want to check what im saying I have to watch the whole flash movie over again. Im not using the actionscript way of playing a sound file, i just put in in layer 1 of frame 1. Is there a faster way to make the sound play just at the point I’m looking at? Or do i have to watch the whole thing every time?
