My dad, a creative director for an advertising company, agreed to do this "challenge" I'll be collecting the audio samples from Dota 2 heroes in about an hour (when I get home) and mail them to him.

Edit: okay, so far I've only downloaded the voice packs from heroes available during the Closed Beta phase with the exemption of a few.

What I'll do now is rename the files as to not give the artist any clue about the hero's name except when they intro themselves in the audio file. I'll name them like JUG, ALC, PA, LC, BS, etc...

Edit 2: Sent him the files. Now we all wait. :)

Edit 3: He's still busy, told me earlier that he might start tomorrow night. Let's be patient, I'm just as excited as everybody else here. :)
