While clinical studies almost universally report few speech and voice complications from uvulopalatopharyngoplasty, there is a paucity of prospective studies concerned with formal acoustic and perceptual evaluation of these patients. This study compares preoperative and postoperative recordings of 32 uvulopalatopharyngoplasty patients. Fast Fourier Transform analyses were made of both long-term spectra of a reading passage and the resonant characteristics of three vowels. Fundamental frequency and reading time were quantified. Polysomnographic studies of these patients were also compared. Finally, listener judgments of "better voice" were made on preoperative and postoperative pairs of the same patients performing a reading task. While the polysomnographic data demonstrated statistically significant improvement in the physical condition of the patients, no perceptual or acoustic measure of voice or speech was significant when preoperative and postoperative scores were compared.
虽然临床研究几乎无一例外地报告悬雍垂腭咽成形术导致的言语和嗓音并发症很少，但关注对这些患者进行正式声学和感知评估的前瞻性研究却很少。本研究比较了32例接受悬雍垂腭咽成形术患者术前和术后的录音。对一篇阅读文章的长期频谱以及三个元音的共振特性进行了快速傅里叶变换分析。对基频和阅读时间进行了量化。还比较了这些患者的多导睡眠图研究结果。最后，让听众对同一患者术前和术后进行阅读任务时的嗓音进行“嗓音改善”判断。虽然多导睡眠图数据显示患者的身体状况有统计学上的显著改善，但比较术前和术后分数时，嗓音或言语的感知或声学测量结果均无显著差异。
