Kam is the most common language of communication among the Dong ethnicminority. It is still widely used in the Dong areas of China. Ever since mid-lastcentury, there have been many linguists from China, as well as overseas, who havestudied the language in depth. Those studies usually focus on one particular dialect(including the standard dialect), compare Kam with other languages, or describe theKam language and culture. This study will look at the Kam language through thelens of historical linguistics, using a comparative study of the historical phonetic datato discover the patterns of phonetic change.Since the late1950s, the sounds of Kam language in the Chejiang region ofRongjiang county have gone through some changes. The biggest change is in theonset of the syllable structure, then in the rhyme, and then in the tone. Thesephonetic changes were caused by internal linguistic factors, social change, languagecontact, and the attitude of the language users. Most historical phonetic change isdue to language contact between one language and the surrounding languages.Studying these patterns of phonetic change is beneficial for the development ofTai-Kadai language research.
