There are many researchers in Brazil working on portuguese speech 
synthesis, but many implementations are closed.

A long time ago I worked on a project called cgstmad. It was a 
simplified Gnuspeech, but it could use other programs as front-ends. I 
used espeak as front-end for brazilian portuguese, but the result was 
not very good, because I didn't tune very well the database.

I found some open source front-ends for brazilian portuguese, but I 
haven't tried them yet.
