every once in a while, i test out this market to see how things have improved. so, i've bought a couple of these products over the years. the last one i bought was 'dragon naturally speaking' : http://www.digitalriver.com/v2.0-img..._dns-talk.html
i dont recall the version i have, since i dont have it on this computer right now. i also remember having to 'train' the software. having just looked at dragon's web site, i noticed right away it said 'no training'. so, that would be a huge improvement.
i remember also that i could use it to do some commands on the computer without having to use the mouse or keyboard and i could do some commands within some sotware. would be interesting to test drive this again and see how comprehensive this has become.
and whereas their site does show some use of commands for some software, i really dont know about photoshop and other graphics programs. so, you'd have to explore this for yourself.
