There's huge variation in Latin American dialects, there's definitely no universal speed of speech.
Do you think on average Latin American Spanish is spoken at the same speed as Spain?
Edit: And regardless of regional variations I am certain that there are Latin American regions which have a generally slower speed of speech than regions in Spain. So the thing that interests me is whether in that case the Spain Spanish has more pauses etc.
Faster in the Caribbean, slower in the Andes
