The researchers discovered, the more data-dense the average syllable is, the fewer of those syllables had to be spoken per second — and the slower the speech thus was. , with a high information density of .91, is spoken at an average rate of 6.19 syllables per second. , which topped the density list at .94, was the spoken slowpoke at 5.18 syllables per second. , with a low-density .63, rips along at a syllable-per-second velocity of 7.82. The true speed demon of the group, however, was , which edges past Spanish at 7.84, thanks to its low density of .49.
