Free Language Courses on FSI
The US Foreign Service Institute offers its language course materials (audio, texts & test) online for free, up to 41 languages:
This site is dedicated to making these language courses freely available in an electronic format. This site is not affiliated in any way with any government entity; it is an independent, non-profit effort to foster the learning of worldwide languages. Courses here are made available through the private efforts of individuals who are donating their time and resources to provide quality materials for language learning.
These languages does not include English, so for people who wants to learn English need seek elsewhere (maybe BBC Learning English?).
Some languages have less course materials than others. For instance, Japanese only has the student text available. Maybe the institute will upload more later.
The sever was overwhelmed by the traffic from Lifehacker readers, so the access to any course materials was temporarily unavailable. Though I could download the pdf file, I couldn’t get one of French audio files. Maybe later. I cannot wait to try it out. 🙂
