I'm going to give this a try. They claim that within 2 weeks they can have even young children speaking conversationally. They have a free trial going on, and wow, what an extensive number of languages to choose from.
Years ago, my need for speaking multiple languages would have come in handy. We had a staff member who spoke Mandarin so she could work with clients who didn't speak English, and it came in really handy. A lot of companies automatically offer other languages, but when it came to languages other than French or Spanish, we'd have to call other branches in advance. Think how wonderful this would have been?
