声学和知觉分析的元音，停顿，和摩擦产生的有和没有人工腭裂。在插入腭部后立即进行记录，并在15分钟的适应期之后进行记录。声学分析的结果表明，在微扰条件下，摩擦频谱发生了显著的变化，元音和停辅音的变化较小。感知数据证实了这些模式，并提供了随着时间的推移薪酬可能有所改善的证据。这些数据与我们之前对咬合条件下语音清晰度的研究进行了比较。对口腔结构的改变(人工上颚)和口腔功能(咬合块固定颌骨)的适应差异也被考虑在内。(C)1996年美国声学学会。
Acoustic and perceptual analyses of vowels, stops, and fricatives produced with and without an artificial palate were conducted. Recordings were made both immediately upon insertion of the palate and following a 15-min adaptation period. Results of the acoustic analyses revealed significant alterations in the fricative spectra under conditions of perturbation with fewer, if any, changes in the vowels and stop consonants. Perceptual data confirmed these patterns and provided evidence of possible improvements in compensation over time. The data are compared to our previous studies of speech sound articulation under bite-block conditions. Differences between adaptation to modifications of oral structure (artificial palate) and oral function (jaw fixation by a bite block) are considered. (C) 1996 Acoustical Society of America.
