Intelligibility refers to understandability of speech; and lack of it can negatively affect children's overall communication effectiveness. Children with repaired cleft lip and/or cleft palate (CL/P) may experience poor speech intelligibility. This study aimed at evaluating speech intelligibility in children with repaired CL/P who had not been referred to speech-language pathology clinics for early intervention. Sixty-four monolingual Persian-speaking children, 32 children with repaired CL/P, and 32 controls aged 3 to 5 years participated in this survey. Their speech intelligibility was evaluated through the Persian Speech Intelligibility Test and was normalized on children 3 to 5 years. Each speech sample was heard by a speech and language pathologist (SLP), as well as 2 nonprofessional listeners. Two objective measures of speech intelligibility including Percentage of Consonants Correct (PCC) and Percentage of Intelligible Words (PIW) were used in this research. Children with CL/P were significantly outperformed by their peers in PCC (p= 0.0001) and PIW (p= 0.0001). More than half of the case group had compensatory errors and 40.6% had obligatory errors. The PCC and the PIW were statistically different in children with different rates of hyper nasality (p= 0.001). Speech intelligibility of children with CL/P is impaired due to their articulation disorders (obligatory and compensatory errors). This survey documents the necessity for speech therapy for increasing speech intelligibility in this population.
可懂度指的是言语的可理解性；缺乏可懂度会对儿童的整体沟通效果产生负面影响。唇腭裂（CL/P）修复后的儿童可能存在言语可懂度差的问题。本研究旨在评估未被转介至言语语言病理学诊所进行早期干预的CL/P修复儿童的言语可懂度。64名讲波斯语的单语儿童参与了这项调查，其中32名是CL/P修复儿童，32名是3至5岁的对照组儿童。通过波斯语言语可懂度测试评估他们的言语可懂度，并将其标准化到3至5岁儿童群体。每个言语样本由一名言语语言病理学家（SLP）以及2名非专业听众听取。本研究使用了两种言语可懂度的客观测量方法，包括正确辅音百分比（PCC）和可懂单词百分比（PIW）。CL/P儿童在PCC（p = 0.0001）和PIW（p = 0.0001）方面明显不如同龄人。超过一半的病例组有代偿性错误，40.6%有强制性错误。不同鼻音过重率的儿童在PCC和PIW上存在统计学差异（p = 0.001）。CL/P儿童的言语可懂度因发音障碍（强制性和代偿性错误）而受损。这项调查证明了对这一群体进行言语治疗以提高言语可懂度的必要性。
