The purpose of this study was to thoroughly analyze postoperative consonant errors by tongue cancer (TC) patients with speech disorders and also to investigate the correlation between the pathological factors and the speech performance using our Consonant-based Articulation Assessment Battery (CAAB).
The participants were 57 monolingual Mandarin TC patients (26 women, 31 men) after surgery (aged 20-80 years). All participants were literate and had normal vision and hearing, enabling them to comprehend and comply with our instructions. In order to quickly evaluate their articulation performance based on the place and manner of articulation, they were instructed to pronounce the characters in CAAB. The analysis removed speech samples impacted by speakers' dialects, while recording and documenting all other responses.
The study uncovered a significant correlation between pathological factors (e.g., size of tongue resection, specific resection site, and tumor size) and the accuracy of consonant articulation. Furthermore, tongue damage predominantly impacts the place of articulation (63.85%) than the manner of articulation (20.78%). The damage in the anterior part of the tongue has the most prominent influence on consonant production.
CAAB can fast capture the idiosyncratic characteristics of speech production by TC patients, and the articulation deficits are quite different from other types of organic or nonorganic speech disorders, for example, cleft lip and cleft palate. Hence, CAAB can be designated as an assessment tool for articulation disorders caused by stomatognathic damages. Our findings also shed light on the possible oral cancer surgery plan and the postoperative speech rehabilitation training.
本研究旨在通过我们的基于辅音的发音评估工具（CAAB），全面分析患有语音障碍的舌癌（TC）患者的术后辅音错误，并探讨病理因素与语音表现之间的相关性。
参与者为 57 名单语普通话 TC 术后患者（26 名女性，31 名男性）（年龄 20-80 岁）。所有参与者均识字，视力和听力正常，能够理解并遵守我们的指令。为了根据发音的部位和方式快速评估他们的发音表现，我们要求他们说出 CAAB 中的字符。分析去除了受说话者方言影响的语音样本，同时记录并记录了所有其他反应。
研究发现病理因素（例如，舌切除的大小、特定的切除部位和肿瘤大小）与辅音发音准确性之间存在显著相关性。此外，舌损伤主要影响发音部位（63.85%）而不是发音方式（20.78%）。舌前部的损伤对辅音产生的影响最大。
CAAB 可以快速捕捉 TC 患者语音产生的独特特征，并且发音缺陷与其他类型的有机或非有机语音障碍（例如唇腭裂）明显不同。因此，CAAB 可以指定为评估口腔颌面部损伤引起的发音障碍的评估工具。我们的研究结果还为可能的口腔癌手术计划和术后语音康复训练提供了启示。
