There are well-known and notable differences in speed for natural languages: While a fast language like Spanish is spoken at a speed of about 6–7 syllables per second, a slow language like German, English, or Mandarin is spoken with 3–4 syllables per second. Language speed correlates with the amount of information carried by a syllable: The more information in the syllable, the slower the language speed.
Since Toki Pona has only a limited number of very simple syllables, limiting the amount of information that they can carry, and it seems to have a speech community as well: Is it spoken at a fast pace like Spanish (or even faster) in real life? Or is it spoken at a slow pace like English?
