R'lyeh'ai

Transliteration
1) Consonant + (h) means something different depending on position on the word and type of consonant:
 * First voiceless Consonant + (h) (except (p) and (s), before a ’ not followed by h, or (p) right after a stop): indicates aspirated consonant; All voiceless consonants thereafter are aspirated unless succeeded by another (h);
 * E.g.: thflthkh’ngha [tʰu.flu.ˈtu.ku.ngʱa]


 * (p)+(h): [ɸ] rather than [p]
 * E.g.: ph’nglui [ˈɸu.nglui]


 * Voiced Consonant+(h) (except L, where it indicates stress that otherwise is pulled away from the syllable): indicates murmured consonant (facultative)
 * E.g.: thflthkh'ngha [tʰu.flu.ˈtu.ku.ngʱa]

2) The apostrophe has different meanings depending on the position on the word and the letters around it. 3) (c) at the start of a word is always a [k], otherwise is a [c]; 4) Doubled consonants (except (h)), usually indicate gemination. Vowels can also be lengthened, indicated similarly by doubling the letter. 5) (h) preceding a vowel in a syllable (including implicit vowels) is pronounced either as [χ] or as [x].
 * Alveolar voiceless Consonant + (h) (except starting (t) ): [t] becomes [θ], [s] becomes [ʃ]
 * E.g.: shoggoth [ʃɵ.ˈgːɒθ]
 * [ ’n ] + vowel indicates that the (n) is pronounced as [ɳ] rather than [n]; ('n) at the end of the syllable is always a [n]
 * E.g.: lw 'nafh [lu.βu.ˈɳa.fʰu]
 * (n) is always a [ŋ] if followed or preceded by (g) in the same syllable
 * E.g.: ph’nglui [ˈɸu.nglui]
 * [ n' ] indicates that rather than joining the next syllable, the (n) ends a syllable on its own and should therefore be pronounced as [nu]
 * E.g.: n'gha [ˈnu.gʱa]
 * E.g.: Cthulhu [ku.ˈtʰu.lu]
 * E.g.: shoggoth [ʃɵ.ˈgːɒθ]

6) The letters (a), (o), (e) and (i) may refer to different vowels on the phonetic alphabet, depending on the position on the word, as well as if the syllable is stressed or not, and if the vowel is preceded by an apostrophe or not. The tendencies are described as follows, with each exception written with a further indentation:
 * (o) is pronounced closer to [ɒ] if the syllable is stressed, closer to [ɵ] otherwise.
 * (e) is pronounced closer to [ɛ] if the syllable is stressed, closer to [ɪ] otherwise.
 * non-stressed vowels may be neutralized the further they are from the stressed syllable.

Phonotactics
The syllabic structure can be simplified to (C)(l,r,n,s,y)(h)V*(h)(C)(n), although there are some exceptions where a syllabe may not have a vowel as a nucleus (hence the *), instead having a syllabic consonant.

Digraphs
Most consonants in R'lyeh'ai correspond to a single symbol, however there are some exceptions: th, ph and sh are respectively pronounced as /θ/, /ɸ/ and / ʃ /.
