I have noted a very significant problem with Express dictate on the Mac. As i dictate, the speed of the recording seems to go up and up and is ultimately unintelligible after about 5 minutes. I get round this by sending my dictation in smaller chunks. I note a post under express scribe which seems to be saying the same thing, but I suspect the problem there is the same (Chipmunk.......). Has anyone else seen this? Using Express dictate 4.03 mac. G5 1.8 DP.
