The purpose of this study was to investigate relationships between speech inconsistency, speech production skills, phonological awareness and nonword repetition (NWR) in 24 preschool-aged Finnish-speaking children with speech sound disorder (SSD) and in 31 children with typical speech and language development (TD). Speech inconsistency was assessed by a picture-naming task repeated three times during one assessment session. The participants' speech production skills were assessed with the Finnish Test for Phonology and a diadochokinetic (DDK) task. Phonological awareness was investigated by the tasks of Rhyme and initial syllable awareness and Syllable segmentation, and NWR by ten 2-4-syllabic nonwords. The findings indicated that the children with SSD were less accurate in speech production and NWR than the children with TD. No difference was found in phonological awareness. Among the children with SSD, speech inconsistency was correlated with accuracy in overall speech production, DDK task, and NWR. Among the children with TD, speech inconsistency was correlated with accuracy in overall speech production, partly with phonological awareness, and with NWR. The results provide support for the idea that when assessing speech inconsistency in children with SSD, a process-oriented approach may be needed in order to obtain an adequately broad picture of their skill profiles.
本研究旨在探讨 24 名芬兰语学龄前言语障碍儿童和 31 名言语和语言发育正常的儿童的言语不一致性、言语产生技能、语音意识和非词重复（NWR）之间的关系。通过在一次评估中重复进行三次图片命名任务来评估言语不一致性。参与者的言语产生技能通过芬兰语音测试和双音节测试（DDK）任务进行评估。语音意识通过韵律和首音节意识任务和音节分割任务进行调查，NWR 通过十个 2-4 音节的非词进行测试。研究结果表明，言语障碍儿童在言语产生和 NWR 方面的准确性均低于言语正常儿童。在语音意识方面未发现差异。在言语障碍儿童中，言语不一致性与整体言语产生的准确性、DDK 任务和 NWR 相关。在言语正常儿童中，言语不一致性与整体言语产生的准确性、部分语音意识以及 NWR 相关。研究结果支持了这样一种观点，即在评估言语障碍儿童的言语不一致性时，可能需要采用面向过程的方法，以便全面了解他们的技能状况。
