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.
