Adults with intellectual disabilities (ID) often show reduced speech intelligibility, which affects their social interaction skills. This study aims to establish the main predictors of this reduced intelligibility in order to ultimately optimise management.
Spontaneous speech and picture naming tasks were recorded in 36 adults with mild or moderate ID. Twenty-five naïve listeners rated the intelligibility of the spontaneous speech samples. Performance on the picture-naming task was analysed by means of a phonological error analysis based on expert transcriptions.
The transcription analyses showed that the phonemic and syllabic inventories of the speakers were complete. However, multiple errors at the phonemic and syllabic level were found. The frequencies of specific types of errors were related to intelligibility and quality ratings.
The development of the phonemic and syllabic repertoire appears to be completed in adults with mild-to-moderate ID. The charted speech difficulties can be interpreted to indicate speech motor control and planning difficulties. These findings may aid the development of diagnostic tests and speech therapies aimed at improving speech intelligibility in this specific group.
成年智障人士的言语清晰度往往较低，这会影响他们的社交互动技能。本研究旨在确定这种言语清晰度降低的主要预测因素，以便最终优化管理。
记录了36名轻度或中度智障成年患者的自发言语和图片命名任务。25名未受过训练的听众对自发言语样本的清晰度进行了评分。基于专家转录，通过音位错误分析对图片命名任务的表现进行了分析。
转录分析表明，说话者的音素和音节表是完整的。然而，在音素和音节层面发现了多个错误。特定类型错误的频率与清晰度和质量评分相关。
轻度至中度智障成年患者的音素和音节表的发展似乎已经完成。所记录的言语困难可解释为表明言语运动控制和计划困难。这些发现可能有助于开发旨在提高这一特定群体言语清晰度的诊断测试和言语治疗方法。
