How about the Clapper (Clap On! Clap Off!)  

I know it sounds cheesy but I'm serious (mostly ;)
If the word itself is going to be fairly invariable in
reproduction, anything that can be made sensitive to the unique
elements in the sound form will work.  A bunch of altered
Clappers in series add up to fire a threshold (each one tuned
to a specific phonetic element in the word).  This will work
best if the word is like "hello" rather than
"antidisestablishmentarianism".
