Postlaryngectomy speech rehabilitation more frequently includes surgical-prosthetic methods since the introduction of a low morbidity tracheoesophageal puncture technique and a one-way airflow valve. This study compares speech using an artificial larynx and, in one case, esophageal speech with speech using a tracheoesophageal puncture and valve in the same speaker. Using nonprofessional listeners, speech was rated for intelligibility and preference. Voice spectrograms were employed for measurement of rate, fundamental frequency, and intensity. While no statistically significant differences were found in mean fundamental frequency or intensity, the rate of post-tracheoesophageal speech was considerably faster. In addition, when individual speakers are compared with themselves, post-tracheoesophageal speech is significantly more intelligible and preferred by naive listeners. We conclude that using the tracheoesophageal puncture with valve should be strongly considered in total laryngectomy patients whose present mode of communication is unsatisfactory.
自低发病率的气管食管穿刺技术和单向气流瓣膜引入以来，喉切除术后的言语康复更多地采用手术-假体方法。本研究比较了同一受试者使用人工喉的言语，以及在一个案例中使用食管言语与使用气管食管穿刺和瓣膜的言语。通过非专业听众对言语的可懂度和偏好进行评分。利用语音频谱图测量语速、基频和强度。虽然在平均基频或强度上未发现统计学上的显著差异，但气管食管穿刺术后言语的语速明显更快。此外，当对个体受试者自身进行比较时，气管食管穿刺术后言语明显更易理解，且更受非专业听众的喜爱。我们得出结论，对于目前交流方式不理想的全喉切除患者，应强烈考虑使用带瓣膜的气管食管穿刺术。
