Comparisons were made of the relative intelligibility of esophageal and artificial larynx speech. Care was taken to minimize the variable effects of individual speaker characteristics. For example, rather than relying solely on data comparisons between groups of different speakers, contrasts were also made between samples from subjects who could use both means of alaryngeal speech. Fifteen proficient male laryngectomized speakers were selected. Five used only esophageal speech, five used only artificial larynx speech, and five produced both forms of speech. Recordings were made while the subjects read 50 PB (Phonetically Balanced) words embedded in a carrier phrase and were transcribed by 30 naive listeners. Differences in intelligibility between esophageal and artificial larynx speech resulted when data comparisons were based on different speaker groups. However, differences were not evident when data from the same speakers were compared. The results were interpreted to highlight the possible influence of individual speaker characteristics, rather than differences between communication methods.
对食管语音和人工喉语音的相对清晰度进行了比较。已采取措施尽量减少个体说话者特征的可变影响。例如，不是仅依赖不同说话者群体之间的数据比较，还对能够使用两种无喉语音方式的受试者的样本进行了对比。选择了15名熟练的男性喉切除患者。5人仅使用食管语音，5人仅使用人工喉语音，5人两种语音形式都能发出。当受试者朗读嵌入在载体短语中的50个PB（语音平衡）单词时进行录音，并由30名未受过训练的听众进行转录。当基于不同说话者群体进行数据比较时，食管语音和人工喉语音在清晰度上存在差异。然而，当比较同一说话者的数据时，差异并不明显。这些结果被解释为突出了个体说话者特征的可能影响，而不是交流方式之间的差异。
