Coatlalopeuh (after Spanish Guadalupe) is the working name for my new
It's got Semitic-style triconsonantal morphology and a triggered verbal
( /k^haKalobuh/, for the curious.)

But none of that's really important right now, just phonology:

Phonetic/Phonemic inventory:
(non-phonemes are enclosed in square brackets; orthography when different
from X-SAMPA is in pipes.)

p [b p^h]    t [d t^h]    k |c| [g k^h]
s [S f]      S |x| [C]    x |h| [C^h h]
l            L |ll|       K |tl|

w |o*|       r [4]        j |e*|

*: When syllable-initial, |e, o| become |hi, hu|, |ih, uh| when

Syllable Structure:
c: any non-semivowel
w: semivowel
v: vowel
A syllable may have no more than three consonants.

If there is one consonant, or a consonant flanked by semivowels, the
consonant is an onset.
If there are two consonants, separate the syllables between them.
If there are three consonants, one must be a semivowel.  Separate the
syllables between the other two.
When there are two vowels in contact, they are separated by hiatus.

Primary stress falls on the character vowel.  (Roots are composed of
two-or-three consonants and a vowel; the vowel appears in every form.)  This
is ordinarily the first syllable of the stem.
Secondary stress falls every third syllable thereafter.

When a stop and /j/ come in contact (in contact meaning separated by
nothing, not even a syllable boundary), the stop becomes voiced and the /j/
is elided.
When a stop and /w/ come in contact, the stop becomes aspirated and the /w/
/s/+/j/ > [S^j]
/s/+/w/ > [f]
/S/+/j/ > [C]
/x/+/j/ > [C^h]
/x/+/w/ > [h]
/r/ > [4] in clusters
High vowels /i u/ preceding stressed syllables in the same word are lowered
to /e o/.  This is optionally noted in the orthography.
