Audiovisual resources

[Hacsa]

Hi, I'm working on a project and I need to add some audiovisual features.
What should I do if I wanted to make a cartoon appears and "say" something?
Let say I'm building a program where you place some answers and depending on the result, you will have a message. I would like this message to be in audio while the user can see a cartoon in the screen. 
I want something like this:

Type your name: Eddy
It responds Funny name (While a cartoon appears on the screen laughing).
It's like a random quote generator, but with audio and visual.

Thanks in advance.
