The evolution of voiced sound is important in the history of Chinese.Previous always stand on the point of view of phonology, paying close attention to the discussion on the sound class. This paper based on this, and also attempt to join the phonetics analysis. According to voiced sound in40places provided by<Sound library of Modern Chinese dialects>, we summary six different types of the evolution mode. At the same time, according to the recording material provided by this sound library and the field survey of Ningbo dialect, we believe that in Wu and Xiang dialects the nature of voiced sound is relaxation sound. As a reference, combined with the tone of the the<Qieyun> Time and Vatican Han sound situation, we believe the voiced sound in<Qieyun> Time is normal voiced. It must experience a stage of differentiation during the process of evolution. The process of evolution is: bâ†'bfi/pâ†'pfi level tone of voiced sound pfi oblique tone of voiced sound <Qieyun>time early Song Shaoyong<The figure of sound>â†'ph level tone of voiced sound belongs to Ciqing. p blique tone of voiced sound belongs to Quanqing.(in or after the Southern Song).The reason of the evolution of voiced sound maybe is that Chinese disyllabism voice makes the stressed syllable in the step of two-syllable highlights. Weak voiced consonants get an opportunity to strengthen, then the evolution happened. During the process of evolution, initial consonant’s pronunciation, articulation, intonation, and many other factors can affect it.
