Today's Toronto Star has an article about a site called Speak2me.cn that uses voice recognition software to help students practice their speaking skills. It's the first free online site I've seen doing this, but it surely won't be the last. In an interesting move, they use product placement in their dialogues as a source of income.
I wanted to try it out, but you really need to be able to read Chinese to use it. If anybody has more success than me, please, let me know what you think.
