Animation Software For Beginners To Create An Animated Movie For Kids?

I would like to create an animated movie for kids which is something similar to ‘Jungle book’ or ‘Aesop fables’(something like that!).What i need is to create the human images easily and add voice when those images move/animate(as if it looks like those images are really speaking).
I am a beginner in this animated movie making,so i would be happy if the tool is pretty user-friendly.
Also i would like to know is there any such tool from Adobe.
