The semivowels [w] and [j] are in complementary distribution with [ɦ],
and may be treated as allophones of the same phoneme.[5]
The voiced stops /d/ and /g/ occur with only about ten words each.[6]
There are five vowels, /i/, /u/, /ɛ/, /ɔ/ and /a/.[7]
The high vowels /i/ and /u/ may also occur as medials.[8]
The Wenchang dialect has six tones on isolated syllabes:[10]
