| 摘 要： | In this study we established a microcomputer based on speech signal processing system and changes of formant frequencies of the vowels/i/accompany the changes in the oral cavity after maxillary surgery and prosthodontic reconstruction. The study found the first formant frequency, for vowel/i/ has no change, while the second formant frequency peak significantly shifted between the preprosthetic and postprosthetic speaking condition after anterior resection of maxillae, and found there is the correlation between the calculation of relative energy error value and the speech intelligible measured aurally (P<0.05).
