摘　　要：目的　比较无喉者发不同元音时的声学参数及气管内压的异同。方法　检测了 2 4例喉全切除气管断端膜样部食管吻合分流发声重建术后患者和 16例喉全切除术后食管音患者分别发元音 a 和 i 时的声学参数 ,测定了 2 0例发声重建术后患者分别发 a 和 i 时的气管内压 ,并进行统计学分析。结果　两组无喉患者发不同元音 a 和 i 时 ,其声学参数无显著性差异 (P >0 .0 5 ) ,发声重建术后患者的气管内压发 i 音时较发 a 音时高 ,有显著性差异 (P <0 .0 5 )。结论　应用元音 a 和 i 在评价无喉者发声的声学参数有一致的临床意义 ;而发声重建术后患者在发不同元音时 。Objective To compare the alaryngeal speakers'voice acoustic parameters and intra-tracheal pressure when they spoke different vowels.Methods 24 patients after tracheo-esophageal shunt phonation by the anastomosis of the membranous portion of the tracheal section with the anterior wall of esophagus after total laryngectomy and 16 esophageal speakers enrolled in this study. The voice acoustic parameters were measured when they spoke soft /a/ and soft /i/. The intra-tracheal pressure of 20 TE speakers was measured when spoke /a/ and /i/.Results There were no significant differences between vowel /a/ and /i/ in the two alaryngeal speaker group. The pressure of TE speakers after Shang's procedrue for comfortable /i/ was higher than that for /a/, and there was significant difference.Conclusion There were the same clinical meanings in evaluating alaryngeal voice acoustic aspect. when using vowel /a/ and /i/. However when using different vowel, the intrtracheal pressure was different in TE speakers.
