The purpose of this preliminary investigation was to identify the location and length of the pharyngoesophageal (PE) segment during esophageal and tracheoesophageal (TE) speech among laryngectomees who were proficient in both methods of vocalization. Four patients who had undergone total laryngectomy and tracheoesophageal puncture served as subjects. Voice recordings were obtained and played to listeners of varying experience with laryngectomees. Videofluoroscopy was performed while the patients sustained "ah" in both modes of speech. Results of these analyses revealed that TE speech was rated as more effective than esophageal speech in all 4 subjects. However, only minimal differences were found in the length and the location of the PE segment during TE and esophageal speech when within subject comparisons were made. This study is the first to compare the physical characteristics of the PE segment during esophageal speech and TE speech as produced by the same speaker.
这项初步调查的目的是,在熟练掌握两种发声方法的喉切除患者中,确定食管发音和气管食管发音期间咽食管(PE)段的位置和长度。4例接受全喉切除术和气管食管穿刺术的患者作为研究对象。获取语音记录并播放给不同经验的喉切除患者听众。在患者以两种发音模式持续发“啊”音时进行视频荧光透视检查。这些分析结果显示,在所有4名研究对象中,气管食管发音比食管发音的效果更好。然而,在进行受试者内比较时,气管食管发音和食管发音期间的PE段长度和位置仅存在极小差异。本研究首次比较了同一说话者在食管发音和气管食管发音期间PE段的物理特征。
