Luis, I'm glad you made contact with me through email.
Our Spanish work has been suspended for a while now. We are looking for a good reason to resume.
Below is a link to a short mp3. It is an example of our initial experiment. It is a European, Madrid-area accent. It should be easy to move to Lat-Am accents. But, I have been told that a cecero accent is helpful to blind Latin-Americans for making clear the spelling of words.
