The question of 'when' to treat speech sounds is often posed in the context of normative data. The new normative data suggest that speech sounds such as /ɹ/ and /l/ are acquired earlier than previously thought. The present study compared the treatment of late-acquired sounds between two age groups of English-speaking children: Young children (4-5) and Old children (7-8). Eight monolingual children with speech sound disorder (SSD) participated in the study. Each child received a criterion-based, standardised, two-phase therapy protocol. Treatment efficacy was measured by examining children's accuracy on real world speech probes. Treatment efficiency was measured by calculating the number of sessions required to meet the exit criterion and the mean session duration. For treatment efficacy, young children learned treated sounds as effectively as oldchildren did. For treatment efficiency, both groups required a comparable number of sessions, but young children required longer sessions than old children. The results suggest that delaying treatment of individual speech sounds is unnecessary and that a range of sounds should be considered as potential treatment targets.
何时治疗语音的问题通常是在规范数据的背景下提出的。新的规范数据表明，像/r/和/l/这样的语音比以前认为的更早被习得。本研究比较了两组讲英语的儿童之间的后期获得声音的治疗情况：幼儿（4-5 岁）和大龄儿童（7-8 岁）。八名患有语音障碍（SSD）的单语儿童参与了这项研究。每个孩子都接受了基于标准的、标准化的两阶段治疗方案。通过检查儿童在真实世界语音探针上的准确性来衡量治疗效果。治疗效率通过计算达到退出标准所需的会话次数和平均会话持续时间来衡量。就治疗效果而言，幼儿和大龄儿童一样有效地学习了治疗过的声音。就治疗效率而言，两组所需的会话次数相当，但幼儿需要的会话时间比大龄儿童长。结果表明，延迟治疗个别语音是没有必要的，应该考虑一系列语音作为潜在的治疗目标。
