    Actually what you describe is an open loop control. ( As you are expecting the human operator to close the feedback loop for you. )

    So are you expecting Y! Answers to provide a design to you?

    .oO( Sadly, we don't get paid enough on Y! Answers for that level of detail. )

    What aspect of this control do you need assistance?

    From what I see described, this is an analog circuit design up to the point of the speech recognition requirement, which then drives it over toward a DSP-controller based design.

    What you have described is a fairly complex embedded system. I would recommend a micro controller with ADC inputs for a light sensor, and voice recognition and a rain sensor. Then you will need a output that controls a relay to turn on and off the lights. The software would have to be able to tell the difference between a flashing light or car head lights otherwise your lights would go out when you need them the most. Lots of little problems to be solved.
