Methods: Before and after restoration use the computer speech lab(CSL) to analyze 12 patients' acoustic characteristics. Then at 1, 2, 4 and 8 weeks, to compare each patient different time's area of energy concentration, the first area of energy concentration band width of consonants /s/,/sh/,/j/; the locus of /t/. Results:There was significant difference between the area of energy concentration and the first area of energy concentration band width in /s/ of the groups before restoration and at the beginning and after one week(P0.05) in other consonants groups.Conclusion: The main area which affects the acoustic characteristics is the anterior part of the anterior palate plate of the removable partial denture. From the acoustics point of view, to lay the major connector on the upper gingival, the median line area are not suitable, while the posterior part of the hard palate fitting to lay it.
