Someone mentioned using PhotoReadng to learn Perl.

Has anyone tried to use it to learn a human language?
At my work, I'm in charge of software dictionaries for about thirty or forty human languages. I have expert contractors to help me manage them, but it bothers me that I can barely say "hello" in these languages. It would be of enormous value to me to learn them -- if not to be a native-speaker, at least to be able to read them, judge grammaticality, and the like.
I haven't bought the course because I don't have the money. But if I can be reasonably certain of getting good results on this problem, it would be a good investment. Has anyone tried this?...
