Yes,I have seen that vid way back which is too funny..Especially when he says the word-"Print" in diff kinds of tones
..& Vista speech recognition aint that bad due to presence of a bundle of easy to use commands.
The only difficult part comes especially when typing a document using Vista speech Recognition..which is shown in the video..I have tried it many a times and have failed miserably..But Vista speech Recognition is designed for People who speak English in
UK accent
But there are ways where u can go under a Voice Training which is totally 4 hrs where Vista identifies/recognizes ur voice accent
Currently I am using
Dragon Naturally Speaking s/w(Trial version)from Nuance which works under Vista and also has support for Indian English
.It works like a charm but is meant only for typing documents,text anywhere and not controlling OS navigation such as Vista Speech Recognition
