That's for Spanish, though, which generally uses a somewhat smaller day-to-day vocabulary since it doesn't have the same weird Romance/Germanic thing that English does.
Most languages end up having about the same information bandwidth, but make different tradeoffs between the number of syllables per second and the entropy per syllable. Spanish and Japanese, for instance, tend to be spoken rapidly and have a more regular set of sounds, but languages like English or Chinese tend to be spoken more slowly and have more different sounds in each syllable. I'd imagine that low frequency languages tend to have large vocabularies that they use, but that's just a guess.
