Ages ago I used to use IBM's ViaVoice for several things. I haven't used a Mac again for about 8 years and am now back on a Mac. What is currently a good program that can do what it did or better. Is ViaVoice still my only option?
As far as I am aware, ViaVoice has not been updated for several years now. You could try iListen from MacSpeech which seems to be regularly updated - see:
Both iListen and Dragon will work with a number of digital audio recorders if you like to dictate text on the move. I personally use Dragon 9 on my 'old' Windows machine and am really impressed with it. Can't comment on the ability of iListen which unfortunately suffers from the £1 = $1 syndrome in the UK so it was more cost effective for me to buy Dragon. Maybe others can comment iListen's ability.
