Sa'och employs a phonemic inventory typical of modern Mon-Khmer languages and, along with the other Pearic languages, shows some phonological influences from the late
Middle Khmer of the 17th century. Like most of the other Austroasiatic languages (outside of
Viet-Muong) Sa'och is not a tonal language. However, also similar to the other Pearic languages, Sa'och is marked by an unusual four-way contrast of vocal
register, or phonation, in its vowel system.
Consonants Sa'och has 21 consonant phonemes. They are listed in table form below.
Vowels Sa'och contrasts nine vowel qualities which can be either short or long, yielding a total of 18 vowel phonemes. Diphthongs do not occur in native Sa'och words, but the diphthongs , , and may be found in loan words from Thai and Khmer. The vowels of Sa'och are: Sa'och employs a system of phonemic
register in which words contrast according to their
phonation, or voice quality. However, unlike these languages, which mostly display a two-way contrast (e.g. between
clear and
breathy voice), Sa'och and other Pearic languages contrast four different voice qualities. In a tonal language, an entire syllable carries the tone but in "register" languages, phonation is manifested only on the vowels. The four voice qualities in Sa'och and their transcriptions, using the base vowel /aː/ as an example, are clear voice (/a/),
creaky voice (/aːˀ/), breathy voice (/a̤ː/) and breathy-creaky voice (a̤ːˀ). ==References==
