Word recognition mechanisms constitute an essential contribution to reading achievement in both deaf and hearing children. Little is known about how children with hearing impairment (HI) manage to read aloud words in the vowelled Arabic transparent script which provides full vowel information. This study aimed to compare word and pseudoword reading accuracy and speed between 32 Lebanese children with HI and 32 younger hearing Lebanese children. The two groups were carefully matched for reading comprehension and oral comprehension levels. Length, word frequency, and lexicality effects were assessed to characterize the functioning of the lexical and sublexical reading procedures. Reading errors were also analyzed to document reading difficulties in transparent Arabic orthography in the sublexical route. The results show significant effects of length, word frequency, and lexicality on reading accuracy and speed in both groups. They also indicate underdeveloped sublexical and lexical routes in children with HI who read less accurately and faster than the younger hearing children. Reading errors are numerous in children with HI. The data are discussed in light of the Dual Route Cascaded model. Suggestions are made about how to improve reading processes in children with HI.

单词识别机制对聋哑儿童和听力正常儿童的阅读成绩做出了重要贡献。人们对听力障碍 (HI) 儿童如何大声朗读元音阿拉伯语透明文字（提供完整元音信息）中的单词知之甚少。本研究旨在比较 32 名患有听力障碍的黎巴嫩儿童和 32 名听力较轻的黎巴嫩儿童的单词和伪单词阅读准确性和速度。两组的阅读理解和口语理解水平进行了仔细匹配。评估长度、词频和词汇影响来表征词汇和词汇下阅读程序的功能。还分析了阅读错误，以记录潜法路线中透明阿拉伯语正字法的阅读困难。结果显示，长度、词频和词汇量对两组的阅读准确性和速度都有显着影响。它们还表明患有​​听力障碍的儿童的词汇下和词汇路线不发达，他们的阅读不如年龄较小的听力儿童准确和更快。HI 儿童的阅读错误较多。根据双路由级联模型讨论数据。针对如何改善 HI 儿童的阅读过程提出了建议。
