Feedback needed on voices

Hi,

Users can create animations in a few minutes on our website. One of the most commonly requested feature is the addition of voices (currently there is no sound ability)

I have created two test animations with sound.

Here are links to the two versions. The first one is using automated voice while the second one is using real voices. Please let me know which one is better. Also let me know if you have any other comments, suggestions, etc.
