speech recognition on Mac?

[fromish]

I use iDictate 1.3 (the version prior to the current 1.51 paid upgrade) and find it functional, strong and more than adequate for my needs. Training works for proper nouns and acronyms, and when there is a problem it is nearly always my fatigue manifesting itself in sloppy speech. You do need a good microphone and quiet room; the built in mic on the iMac kind of works but introduces too many errors. The various noise suppression mics, including the one that comes with the program, work well. You need Leopard and an Intel for best results.

The program is great, the company less so. MacSpeech tends to be defensive in their reactions, spotty in their support, and undercapitalized so that they charge for what should be free upgrades.
