高田壮语的单字调近５０年来由８个演变为６个，这是调值相近声调自然归并 进而导致声调系统内部重新整合的结果。根据变调，可以透视高田壮语声调系统的 表层和深层两级形式。声调演变所引起的声韵变化主要表现为非音质音位特征的转 换。高田壮语调类归并这一特殊音变现象可能预示着今后壮语及壮侗语族声调的一 种发展趋势。 Takada’s monosyllables evolved from 8 to 6 in the past 50 years, which is the result of the natural mergence of similar tones and the consequent internal re-integration of the tone system. According to the variation, one can look at the surface and deep two-level forms of the Takada Zhuang tone system. The change of phonology caused by the tone evolution mainly manifests as the conversion of non-tonal phoneme features. The combination of Takada Zhuang dialect and this special phonetic variation may herald a trend of development in the future Zhuang language and Zhuang Dong language.
