understand
the commands given to the program.
In computer,this needs a conversion of signal form analog
to
digital. It is also necessary for a computer to have a digital
databar i.e.
vocabulary of words, and a fats means of comparing this data
with single.
We can make voice recognition program faster many time if the
whole
vocabulary is added to RAM.
External conversion or any loud noise can produce
wrong input. We can avoid this only by using the system in claim
place.
The user should provide with good pronunciation skill.
