现代高棉语和古高棉语音系
Modern Khmer and Old Khmer Phonetics

古高棉语到现代高棉语辅音经历了浊音清化和辅音送气化，浊音清化导致语言出现了两个音域，为了满足表达需要，元音产生了补偿性变化，元音开始裂变、单元音复化，语言中出现大量二合元音音位，元音音位数量倍增。本文将分别从辅音、元音和音节等方面对现代高棉语音系和古高棉语音系进行描写，以便更直观地了解柬埔寨语的演变。
The consonant system of old Khmer evolved into the consonant system of modern Khmer through processes of voicing devoicing and voicing aspiration, which led to the emergence of two sound ranges in the language. To meet the needs of expression, vowels underwent compensatory changes, and began to split, monophthongs became diphthongs, and a large number of diphthong phonemes emerged, causing the number of vowel phonemes to multiply. In this paper, the phonological systems of modern Khmer and old Khmer will be described separately from the perspective of consonants, vowels, and syllables, in order to better understand the evolution of the Khmer language.
