Bahasa Vietnam Sebagai Bahasa Nada

Its complexity is a natural result of the fact that the language belongs to different proto-languages, i.e. Austro-Asiatic, Sino-Tibet, Thai-Kadai and Hmong-Dao. Therefore, it is interesting to study Vietnamese. Vietnamese is a tonal language. Pitch is a crucial part in tonal languages since it helps create suprasegmental phonemes to produce different lexical meaning.
