  • (a) accepting environmental sounds and speech sounds from the user;

    (b) converting said environmental sounds and speech sounds into a plurality of electrical signals;

    (c) filtering said plurality of electrical signals that are outside a range of speech to produce at least one filtered electrical signal;

    (d) comparing said at least one filtered electrical signal with a set of user dependent and user independent speech sounds to determine whether a first valid command has been uttered;

    (e) prompting the user to utter a second valid command upon determining that said first valid command has been uttered;

    (f) repeating steps (a) through (c) and comparing said at least one filtered electrical signal with said set of user dependent and user independent speech sounds to determine whether said second valid command has been uttered;
