Kiâkui [kjɑ:.'kɯɪ] is a project of mine which I have been working on for some times. Until now only the phonology and ortography is finished, but I thought I'd give you a look at it.
Phonology
Consonants (Onset):
p pʰ b~ɓ t tʰ d~ɗ tɕʰ dʑ k kʰ g ʔ
m n ɲ
f s h
w l j ʀ
Note: [ɓ] and [ɗ] appear only in absolute initial position and after glottal stops.
Romanization:
p ph b - t th d - ch j - k kh g / m - n - nh
f - s - h / w - l - y - r
Consonant clusters:
pw pj bw bj tw dw tɕw dʑw kw kj gw <pw pi bw bi tw dw cw jw kw ki gw>
mj <mh>
sw sj <sw x>
Vowels (monophthongs)
a æː/ɑ:/ɜ: - ɛ ɛɪ~e: - ɔ ɔʊ~o: - ɪ~i i: - ɯ~u ɯ:~u:

Allophony:
1. [ɪ] occurs in closed syllables, [i] in open syllables
2. [ɯ] and [ɯ:] occur in closed syllabes, [u] and [u:] in open syllables respectively.
3. [ɑ:] is used in open syllables before back vowels, [æ:] is used in oppen syllables before front vowels, [ɜ:] in closed
