Would it work to just bounce a laser* off of a piece of silvered mylar - letting raw speech vibrations shake the mylar? [this is as for the sending end]
...As for a simple receiver, could you bounce the laser up into a flat piece of black construction paper with a small number (50-100?) grains of sand, (perhaps needing a hearing cone to help)?
* which could also be sunlight

Your transmitter will work, your receiver won't.
but you could bounce the signal onto a simple solar cell
connected to a set of headphones and you should be
able to receive a weak signal...
Your receiver won't work because light won't move the paper and the grains of sand.....

Naw. The laser have anywhere near enough power to impart any kind of detectable motion on the paper. There are simple photoreceptors you could use. The thing that the light beam that rings the bell at Radio Shack hits would work.
