Hi Vanessa,
I think it is a great idea for the home page. As others have said it may be much utilizing it everywhere else. What is great is that it makes you stop and listen. Rather than having to read the words, your animation says it all for you! It really is a great attention grabber.
My only thought was that the talking went on a little bit longer than my attention span allowed. Quite possibly that is because I just finished working for the day though.
All in all, I think you should definitely keep it for the home page! It's very cool.
