Dahoukki/Sound Changes

From Modern Japanese

Nasal vowel and consonant deletions feature prominently throughout, and the first set starts right away.

Nː → N
mb {mj nd} {nj ɲj ɲʥ} ŋg → m n ɲ ŋ
Vmp Vnt Vŋk → Ṽp Ṽt Ṽk
V → Ṽ / _N
N → Ø / Ṽ_#;  Ṽ_C
m n ɲ ŋ → β ð ʝ ɣ / Ṽ_V
m n ɲ ŋ  → b d ʣ g / Ṽ_
w → u
ã ĩ ũ ẽ õ → ə iː uː e oː
ãː ĩː ũː ẽː õː → a iː uː ɛː oː

In that same vein, is the replacement of many remaining nasal consonants with their non-nasal counterparts.

m n ɲ ŋ → b d ʣ g / #_
ʝ → ɣ
m n ɲ ŋ → β ð ʝ ɣ / V_V

Loss of any geminate consonants.

Cː → C

Simplifications of palatal clusters into single consonants.

pj tj kj sj hj → t ʨ ʨ ɕ ç

Followed up by a skad of vowel changes, deletions and such. Some of these changes are blocked in certain contexts which is shown with the double slash (//), i.e. "except when...".

o → u / _#
e u → i Ø / _#
e i o → ɛ ɪ ɔ
u → ə / _CC // CC_#; #_#
u → i / h_ // CC_#; #_#
u → i / ç_ // CC_#; #_#
Vː → V

Some more consonant change.

f → x
β → x / _#, _u
x → h
ç → k / _#
ç → h
{ð ɮ} → r / _#
j ɣ → ʑ g / _#
ɪ → ə / _C
ɮ → j / V_V
ɮ → ʑ
j → ʑ / _C

More death to nasals.

N → Ø / _#
Ṽ → V / _#

Another round of heavy vowel change.

ɛ ɪ ɔ {ə o} → e i o u / _#
ai → e
e → i / _#
{əə aə} {ɪə iə} uə {ɛə eə} {oə ɔə} → a i u e o
ɪ → ə
ai → e

Some epenthesis of glottal stops, as well as deletion of many instances of /u/ and schwa.

Ø → ʔ / V_V
{ə u} → Ø / C_r  // C_r#; #C_; #_r 
{ə u} → Ø / _rV; VC_CV
Ø → ə / #C_C
{ə u} → Ø / _rV
Vʔ → ʔV / #_C
Vʔ→ Vː / _C
Vː → V
{əʔ uʔ} → ʔ // C_
{ə u} → Ø // ʔ_ʔ
ʔ → Ø / _C

Fortition of a series of consonants, as well as general consonants shifts.

β ð ɣ ʦ ʣ s z → b d g ʨ ʥ ɕ ʑ
ji → jə
j → ʑ / _C
{ʔ h} → g

Consonant voicing dissimilation. Here, "D" means a voiced stop, where "T" is being used here to refer to any unvoiced consonant.

CT → CD
DC → TD
D → T / _#

A cute little rule that disallow so much deletion from earlier steps that we are left with a bare consonant, so: epenthesis.

Ø → ə / #C_#
