with dragon naturally speaking u can "practically "do away with your mouse and keyboard.
or this is wat the company states.
the ibm viavoice is not for Indian accent.
but the Latest dragon naturally speaking(ver 8) has been updated with Indian accent and claims to have 99.9 % accuracy. Ofcourse this will come only after complete training.
i use dragon version7 . its good but i still think it does the same job like office 2003. (ofcourse u can control ur mouse movements and browse the net with this software.)
so i think Version 8 must have much better options (including these)
