Animating your voice using online application

Hi!
I would like to know more about Skype Voice Changer. How do I use this? Can I download it in my laptop or desktop? What are the system requirements to make this software work? What are the features that I can use to change my voice pitch? Can save it to my hard disk drive? What are the formats that I can use to export the recorded voice? Do I need any plug-ins in my computer or browser to make this software work?
