Speech is insane for a dumb unit.

I have a suspicion the "requirement" for speech probably is just the
professor's own, uhh... appreciation of speech synthesis or some such.

Many years ago for an opto-electronics lab I built a heartbeat detector based
on an IR LED and phototransistor (you put your finger on it) and a bunch of
fancy op-amps performing low-noise amplification, filtering and detection; it
fed a flashing LED and a beeper every time it detected a beat. I showed it
off at the appointed time, and the main feedback I received was, "nice... but
shouldn't there be a digital readout of beats per minute!" Arrrrggh!
