Thanks to Jonathan, you can learn to speak Catalan on ielanguages.com.
Catalan is spoken by 11.5 million people, mostly in eastern Spain (Catalonia, Valencian Community, Balearic islands) as well as in southern France, Andorra, and Sardinia, Italy. Barcelona is the largest Catalan-speaking city, and Catalan is recognized as a co-official language with Spanish in the regions where it is spoken in Spain.
The first thirty lessons of the Catalan tutorial are now available.
If any Catalan speakers out there can provide audio files or spontaneous listening resources, please let me know!
