In this paper, we evaluate the speech intelligibility of two groups of Spanish-speaking people who have undergone laryngectomies: a group who used esophageal speech and a group who used tracheoesophageal (TES) prostheses. Audio recordings of 24 Spanish words produced by each talker were presented to a group of normal-hearing naive listeners who phonetically transcribed their responses. Listeners' responses were registered in confusion matrices. Results indicate that differences between these two groups of patients appear when we consider phoneme types. The difficulty in producing the voicing distinction appeared in both TES and esophageal talkers. This finding is consistent with studies of English-speaking laryngectomized patients. Considering manner of production, fricative consonants had the highest number of confusions with other phoneme class in the TES group, whereas in the esophageal group nasals resulted the highest number of confusions. However, ANOVA showed that differences between the two groups were not significant.
在本文中，我们评估了两组接受喉切除术的讲西班牙语人群的言语可懂度：一组使用食管语音，另一组使用气管食管（TES）假体。每位讲话者说出的24个西班牙语单词的录音被呈现给一组听力正常的未接触过相关内容的听众，这些听众对他们的反应进行语音转录。听众的反应记录在混淆矩阵中。结果表明，当我们考虑音素类型时，这两组患者之间存在差异。在使用TES假体的患者和使用食管语音的患者中，发出浊音区别都存在困难。这一发现与对讲英语的喉切除患者的研究一致。考虑发音方式，在使用TES假体的组中，擦音与其他音素类别的混淆数量最多，而在使用食管语音的组中，鼻音的混淆数量最多。然而，方差分析表明两组之间的差异不显著。
