you can learn to speak Chinese any where any time, because smart phone is always with you, see this free software app, frankly speaking, its really useful. [www.greatwall.co]

Interesting, but when I learn a language I always follow up study with practical use (find a native speaker to speak with every single day). I'm not sure how practical this is, but hey for free I guess it could help you study.

I don't think i can learn like this. It is a great gadget but .. let's be more serious. They can build something .. if they want to. A gadget that translate vocal any language in english.. something like Google translate . What do you think about that??
