A comparative study of the voice with sustained phonation of the vowel /a/ was made in 3 groups of male patients: (1) 20 patients receiving total laryngectomy for epidermoid carcinoma of the larynx who had acquired good voice quality after a phonatory fistuloplasty with a Herrmann voice prosthesis; (2) 20 patients undergoing total laryngectomy for epidermoid carcinoma of the larynx who had learned esophageal speech; and (3) 20 subjects with normal voices. Statistical analysis yielded significant differences in fundamental voice frequency between the 3 groups, with the patients with phonatory prostheses revealing the closest to a normal voice. For other parameters used, such as jitter, shimmer, and harmonics/noise ratio, voice quality with a phonatory prosthesis was similar to that obtained with esophageal speech.
对三组男性患者进行了元音/a/持续发声时嗓音的比较研究：（1）20例因喉表皮样癌接受全喉切除术的患者，在采用赫尔曼语音假体进行发声瘘管成形术后获得了良好的嗓音质量；（2）20例因喉表皮样癌接受全喉切除术并学会食管言语的患者；（3）20名嗓音正常的受试者。统计分析显示三组之间的基音频率存在显著差异，使用发声假体的患者嗓音最接近正常。对于所使用的其他参数，如抖动、闪烁和谐波/噪声比，使用发声假体的嗓音质量与食管言语获得的嗓音质量相似。
