Now, to be fair, Chris Rock was talking about voice acting for animation (although he could have clarified that a bit better). Yes, his delivery was funny. Hell, I laughed at first. Then I realized that his words were to full-time voice-over artists what Andy Serkis' words were to VFX professionals. Tara Strong even took note of this message well before I did.

The award that Mr. Rock was introducing and announcing went to a movie (Rango) that used a technique that has been coined "emotion capture." It is a process where not just the voice acting was used, but the physical acting was also referenced by the animators, as shown in this featurette:
This looks and sounds to me like these actors didn't just go in a booth, say some lines, and collect a million dollars, now doesn't it?
