    I think the best that can be realistically accomplished using only analog is a circuit that would produce an output state change when it recognizes a single syllable word, from a single recognized voice. I would imagine that the early pioneers in this technique used a spectrum analyzer on the subject voice and word. If they used 9 frequencies extracted from the SA results then they could use 9 BPFs in a scheme like this. I would guess that similar schemes were experimented with in during the vacuum tube era. It does use logic, so it's not strictly analog but it's definitely not uC or uP based.

    Edit: By the way, wasn't Johny 5 from 'Total Recall'?
