Swedish has a complicated prosodic system, compared, for example, with English. A large proportion of Swedish children with language impairment (LI) have prosodic problems to some extent. There are few descriptions in the literature of prosody intervention, which means that clinicians must rely on their overall linguistic and therapeutic knowledge when designing intervention for prosodic problems. The aim of the present study is to design an intervention package for prosodic problems in children and to evaluate this intervention. The article reports a single subject multiple baselines case study. The participant was a boy (aged 4 years and 6 months) with prosodic problems, mainly on word level but also on phrase and discourse level. The intervention was devised to address his problems and focused on word level prosody. The intervention was carried out over 6 weeks, comprising six 60-minute sessions. Post-intervention assessments were carried out immediately after intervention and 9 weeks later. The participant improved his overall prosodic skills significantly, as assessed by a procedure designed to capture prosody at word, phrase and discourse level. An evaluation of a spontaneous speech sample was also made by a panel of three experienced listeners, and they found some improvement in the participant's prosody in connected speech, although this was not significant.
