Abstract

The current research pursues the study of developing the Persian test of speech consistency and investigating speech consistency in normally developing children in Iran. After developing the Persian test of speech consistency, the obtained speech samples of 317 participants (163 girls and 154 boys) were analyzed. This test of consistency includes 27 items. Experts’ consensus over the characteristics of the Persian test of speech consistency was above 85%. Different age groups had statistically significant differences for the mean scores of the variable responses (p < .001), consistent correct (p < .001), and consistent incorrect responses (p = .007) in the Persian test of speech consistency. Also, there was a high value for the inter-rater reliability (ICC = .88, p < .001) as well as the moderate value for the test-retest reliability (ICC = .89, p < .001). The Persian test of speech consistency is regarded as a reliable and valid scale for measuring the speech consistency in Persian-speaking children. Future studies are proposed to investigate the speech consistency in Persian-speaking children with various kinds of speech sound disorders.

摘要

目前的研究致力于开发波斯语语音一致性测试并调查伊朗正常发育儿童的语音一致性。在开发了波斯语语音一致性测试后，对获得的 317 名参与者（163 名女孩和 154 名男孩）的语音样本进行了分析。该一致性测试包括 27 个项目。专家对波斯语语音一致性测试特征的共识在85%以上。不同年龄组的变量响应（p < .001）、一致正确（p < .001）和一致不正确响应（p= .007) 在波斯语的语音一致性测试中。此外，评分者间信度（ICC = .88，p < .001）和重测信度中等值（ICC = .89，p < .001）。波斯语语言一致性测试被认为是衡量波斯语儿童语言一致性的可靠和有效的量表。未来的研究建议调查具有各种语音障碍的讲波斯语的儿童的语音一致性。
