This study comprehensively compared the speech of laryngeal speakers (L), tracheoesophageal speakers (TE), good esophageal speakers (GE), and moderate esophageal speakers (ME) to determine the consequences of TE versus E speech rehabilitation. Twenty speakers (five in each group) were each recorded while reading 16 sentences, and their recordings were analyzed acoustically and perceptually. Acoustic analysis included duration, intensity, fundamental frequency (F0), intonation, and voice onset time measurements. Perceptual analysis included intelligibility and acceptability judgments by naive listeners. The main acoustic results showed that L speakers differ significantly from all alaryngeal speakers in F0 and intonation production. Moderate esophageal speakers differed significantly from all other groups in duration measures. Perceptual results revealed that L speakers were most intelligible and acceptable, whereas ME speakers were least so. Tracheoesophageal speakers were more acceptable than GE speakers but not more intelligible. Significant correlations emerged between F0, duration measures, and acceptability, and between F0 and intelligibility. Also, a significant correlation emerged between acceptability and intelligibility. Findings emphasized the importance of categorizing esophageal speakers into groups based on their speech proficiency level.
本研究全面比较了喉发声者（L）、气管食管造瘘发声者（TE）、优秀食管发声者（GE）和中等水平食管发声者（ME）的言语，以确定气管食管造瘘发声与食管发声康复的效果。20名发声者（每组5名）在朗读16个句子时进行录音，并对其录音进行声学和感知分析。声学分析包括时长、强度、基频（F0）、语调以及起音时间测量。感知分析包括由未受过专业训练的听众进行的可懂度和可接受性判断。主要声学结果表明，喉发声者在F0和语调产生方面与所有无喉发声者存在显著差异。中等水平食管发声者在时长测量方面与所有其他组存在显著差异。感知结果显示，喉发声者的可懂度和可接受性最高，而中等水平食管发声者最低。气管食管造瘘发声者比优秀食管发声者更易被接受，但可懂度并不更高。F0、时长测量与可接受性之间，以及F0与可懂度之间存在显著相关性。此外，可接受性与可懂度之间也存在显著相关性。研究结果强调了根据食管发声者的言语熟练程度对其进行分组的重要性。
