    Elaborate on the the requirement "How to process the speech password to be door open & close"

    for example

    Listen for person's presence using the microphone input
    Record persons verbal command
    Do command identification on speech (open or close)
    Do person identification on speech
    Check if person is in database
    Control door

    Yes you can use the parallel port and VB6 to control of the door. See A tutorial on Parallel port Interfacing

    Please take alook at the C source code at A tutorial on Parallel port Interfacing
    You can also use the inpout32.dll to make the code simpler
