Does anyone have experience with using this, with ExpressScribe or some other program? I've been asked to look into getting this, primarily to transcribe audio recordings, and the reviews of Version 10 are very mixed. I'm specifically looking at DNS Preferred, not Standard. For those who do work successfully with it, I'd like to know whether you've used it with audio files, how they were generated, what worked and what didn't. Or if there's a better speech to text engine you can recommend? Thanks, KRN
