I posted my project on Facebook and a couple of my friends have contributed nicely. I still have a glitch I can't identify that will occasionally kick a caller off. I think it's when the recording isn't available at the moment of the next loop.
Also I think I need to put in some limit or something. I have two callers who provided over 40 samples and there is only 36 words (26 letters + 10 numbers) in the set.
But this is a good!
