This dissertation is engaged in increasing the efficiency of the variable speed variable pitch WPGS. The technical and operation characteristics of the system are analyzed and the control schemes are researched in theory and simulation. And then, the emulation of WPGS in lab is also explored in order to verify the affectivity of the control scheme.

Based on＂The Data Bank System of the Standard Phonetic Features of Different Level in PSC＂, the thesis analyzes the variants of affricative versus fricative in syllables: z, c ,s - zh, ch, sh - j, q, x which are obscure in physiology; analyzes timbre phonetic variants aroused from the different match of seven main simple vowels and initials as well as the tonal patterns with the help of drawing the synthetic spectrograph and pitch spectrograph. So that the data can be offered to describe phonemes in 396 syllables in common use according to the acoustic analysis.
