Mostly unrelated, but there was a study [0] some time ago which said that the information rate of all languages was roughly the same. So if a language had more data conveyed per syllable, then it might be spoken slower for instance. 0: https://www.science.org/doi/10.1126/sciadv.aaw2594
Spanish (Spain) is often spoken faster than English. And in my experience if you translate something from English to Spanish the text becomes 20%–30% longer.
The weird one is that Latin American Spanish is spoken much slower, but with the same information per syllable (presumably). I always wondered if the information rate would actually be the same for Spanish (LATAM) and Spanish (Spain) - my suspicion is that it's lower in LATAM. Perhaps pauses and connective words could account for the difference though?
