I don't know how far it will proceed.
p t k kʷ ʔ <p t k kw '>
t͡s k͡s <c x>
s ɬ h <s h>
m n ŋ <m n ng>
l ɹ j w <l r y w>
i ʉ <i u>
o <o>
ä <a>
Vowels can be short or long, written <ii uu oo aa>.
/l m n ŋ/ can also be syllabic.
Syllabic consonants can appear between two other consonants and word-finally.
/p t k kʷ ʔ s h m n ŋ/ can be geminated. /hh/ is pronounced [x:].
All consonants can be preglottalized. Preglottalization works like gemination in that
- It cannot appear word-initially
- It cannot appear in consonant clusters
Preglottalized consonants differ from geminates in that non-stop geminates can follow long vowels.
Maximal syllable structure: CVC (or maybe CVʔC)
(Some person prefixes are stops that can precede a non-stop consonant.)
Maybe Japanese-style /h/ -> [f] / _ʉ
also
/ʉ/ -> u / kʷ _
/i/ -> e / adjacent to /w/ or /j/
Phonetic words can have one or zero high tones. The high tone can however be spread to several adjacent syllables. Two no-adjacent syllabls cannot have a high tone.
Xiwook is a prototypical stress language. The stress lies on the second syllable. Nearly all words have at least two syllables.
