1. Dragon Naturally Speaking by Nuance. Dragon is pretty much the gold standard for dictation. And Nuance seems to have invented the entire industry before dictation was cool. They have deep roots in medical transcription, for example. Die hard dictators swear by the PC version of this software. The Macintosh version was (puzzlingly) discontinued last year. Since Dragon has such a big reach, lifelong Mac users have been known to purchase cheap PCs to run this software.
