I remember reading an article which explained how to implement speech 
recognition on an old Motorola chip (MC6800?). IIRC the key to being able to 
pull this off, is making a number of simplifying assumptions. It is not 
speech-to-text the way speech recognition is normally understood.

Can't find it now. :-(
