[Corpora-List] Question re access to corpora of transcribed conversational Spanish

[Steven Johnson]

Was wondering if anybody on this forum could advise me concerning  
these questions:

1. What are the most extensive corpora available of transcribed oral  
speech in Spanish?

One I saw had some speeches by Fidel Castro. That's fine, but I'm  
looking for informal conversation. Could be from movie and TV  
dialogs, or more authentic sources.

2. How can I get permission to browse the raw text in such corpora,  
assuming they exist?

I'm not so interested in searching for particular words and phrases.  
Rather, I'd like to read reams and reams of authentic transcribed  
conversational speech.

Thank you.
