I'm showing my European bias here.
I should have thought of Korean. The Hangul script is syllabic with a
very straightforward and easy to learn structure. Wikipedia tells me
that they have 19 consonants and 21 vowels, so you could just pick 16
consonants and 16 vowels to construct 256 syllables. That would even
make UUIDs pronounceable.
