Hi again, Just a quick search on Google shows up loads of info, like these: http://www.faqs.org/docs/Linux-HOWTO/Speech-Recognition-HOWTO.html http://www.generation5.org/content/2002/howsrworks.asp This is also very interesting: http://www.ee.columbia.edu/~stanchen/e6884/slides/lecture12.avsr.pdf The Google result: http://www.google.ie/search?hl=3Den&q=3Dvoice+recognition+theory&btnG=3DGoo= gle+Search&meta=3D Tamas On 9/7/07, Tamas Rudnai wrote: > > Hi, > > It could be, but highly unlikely as every speech recognition needs a bit > of training so that the operator 'teaches' his/her voice to the system > otherwise it would not easy to recognise words.
