Final variations with tones in Chinese dialects

Final variations with tones refers to the phenomena that finals change in terms of contrasting tonal features. There are two contrasting pairs between tones, the long with the short and the high with the low. Generally, the long tone conduces to the diphthongization of a monophthong or coda addition, which lengthens the whole final; and the low tone leads to the diphthongization and the downward moving of a high vowel. All these changes can be regarded as the intensification of the final.
