Hmm.. i think there's one 'Dragon' voice recognition.. which is the best in this.. But i guess all these voice recognition software are sharewares(?!).. is any free voice recgoniton sw available?
well there are dragon's naturally speaking and via voice (or viva voice..not sure bout the name) which are speech recognistion softwares but they require lot of practice and patience as you have to teach them to recognise your voice by reading out reams of text first..you can try them out
