Alvin, I don't know where you would find one of these today, but
my wife bought a cassette recorder several years ago that would be
just the ticket: I believe it was by Panasonic, I'll find out if
you need the name. It looks like a standard portable casette deck,
but has a little slide pot that runs from something like 50% to 
maybe 250% speed. The principle intent of this was to allow you
to play a lecture tape back *faster* than normal, to get more
comprehension in a given period of time, but it can also sloowwwww
things down, and have them still quite understandable. The signal
procssor was mostly a single analog shift register chip made especially
for this purpose...
