Although group studies provide necessary information about the range and frequency of phenomena in phonological development, individual profiles (case studies) can be used to describe entire phonological systems in detail. Profiles from different languages can highlight similarities and differences across languages that may be less obvious in group studies. The current issue presents profiles of children with protracted phonological development (PPD: speech sound disorders) from 16 languages (Akan, Kuwaiti Arabic, Bulgarian, Canadian English, Farsi, Canadian French, German, Greek, Icelandic, Japanese, Mandarin, Polish, European Portuguese, Slovenian, Granada Spanish, Swedish). Utilising a constraints-based nonlinear phonological framework, each profile describes a child's strengths and needs in word structure, segments, features and their interactions and suggests an intervention plan. Where available, follow-up data from after clinical intervention are included. This introductory paper provides the theoretical background for the papers and reflects on the findings, drawing out particular themes and implications for phonological and developmental theories and clinical intervention.
虽然群组研究为语音发展现象的范围和频率提供了必要的信息，但个体档案（案例研究）可用于详细描述整个语音系统。来自不同语言的档案可以突出显示群组研究中不太明显的语言之间的相似点和差异。本期特刊介绍了来自 16 种语言的儿童（延长语音发展障碍：语音障碍）的档案（加纳语、科威特阿拉伯语、保加利亚语、加拿大英语、波斯语、加拿大法语、德语、希腊语、冰岛语、日语、普通话、波兰语、欧洲葡萄牙语、斯洛文尼亚语、格拉纳达西班牙语、瑞典语）。每个档案都利用基于约束的非线性语音框架描述了孩子在单词结构、音段、特征及其相互作用方面的优势和需求，并提出了干预计划。在有后续数据的情况下，也纳入了临床干预后的随访数据。本文为各篇论文提供了理论背景，并对研究结果进行了反思，提出了对语音和发展理论以及临床干预的特定主题和影响。
