Cáiuén is the creation of Pangus Ho, who uses it to write
his con-dialect of Chinese,
(Cáiŋŷ/才语), but with modifications it's actually
suitable to write any Sino-Tibetan language, including standard Chinese.
Each syllable is written in a block consists of 3 parts:
(tóu/头) the initial consonant
(zoŋ/中) the tone and the initial vowel
(uêi/尾) the final vowel and consonants
Each part consist of exactly 20 characters (which makes them symmetric),
so they can be built up to 8000 syllables.
The parts can be arranged in at least 3 styles:
A stripe (-) means zero consonant or zero vowel. For example the
syllable "ân" is written
(-, -ˆ, an);
"ə" is not pronounced unless it appears after /i/ and /y/. "e", "eh"
and "an" are pronounced /ɛ/, /ɛʔ/, and /ɛn/
respectively if they appear after /i/ and /y/, otherwise they are pronounced
/ʌ/, /ʌʔ/, and /an/. "z", "q" and "x" are pronounced with
/ɕ/ when they appears before /i/ and /y/, otherwise /ʂ/.
44, 24, etc are tone sandhi. 1 is the lowest
tone while 5 is the highest. 24 means from mid-low tone
rises to mid-high tone, etc.
