You can probably still get a cracked version of rosetta stone from the pirate bay. I got it years and years ago, with all the languages, and tried a few out. It looked extremely promising from what I tried out. Most of it you use a mic for and it evaluates you on pronunciation. Lots of matching games and stuff too. Pretty well structured. No wonder it costs hundreds of dollars. Im re-downloading it now just for shits and giggles(https://thepiratebay.org/description.php?id=8817203). Its a massive file, and will take a few hours, but it looks like a good version.
