The purpose of this study was to compare the intelligibility of two types of alaryngeal speech commonly used after total laryngectomy. Four male oesophageal speakers and four male tracheo-oesophageal speakers read a series of monosyllabic words, multisyllabic words and sentences. The monosyllabic word list consisted of several minimal pairs for each of eight phonetic contrasts; multisyllabic words and sentences were not selected on specific phonetic grounds. Audio recordings of all subjects' readings were presented to eight naïve adult listeners who completed both an item identification task and a scaling procedure. The item identification task revealed higher intelligibility fpr tracheo-oesophageal speakers than for oesophageal speakers during the monosyllabic word condition. Results from the scaling procedure indicated that listeners' subjective intelligibility ratings were also higher for the tracheo-oesophageal speakers than for the oesophageal speakers. Moreover, a high positive correlation was found between the speakers' intelligibility scores obtained from the word identification task and the scaling procedure.
本研究的目的是比较全喉切除术后常用的两种无喉语音的可懂度。四名男性食管发音者和四名男性气管食管发音者朗读了一系列单音节词、多音节词和句子。单音节词列表由八个语音对比中的每一个的几个最小对组成；多音节词和句子不是基于特定语音标准选择的。所有受试者朗读的音频记录被呈现给八名未受过训练的成年听众，他们完成了一项项目识别任务和一个评分程序。项目识别任务显示，在单音节词条件下，气管食管发音者的可懂度高于食管发音者。评分程序的结果表明，听众对气管食管发音者的主观可懂度评分也高于食管发音者。此外，从单词识别任务和评分程序获得的发音者可懂度分数之间发现了高度正相关。
