Prosodic aspects of repetition in Swedish-speaking children with developmental language disorder

Purpose: To examine repetition of stress and tonal word accents in real words and non-words in Swedish-speaking children with developmental language disorder (DLD), and to investigate the relation of prosodic repetition to measures of language ability.

Method: A cross-sectional study was undertaken with 30 monolingual Swedish-speaking children with DLD, mean age 4;11 (years;months) and 29 age-matched controls, mean age 5;1, who repeated words and non-words with systematically varying prosody. Group differences for the repetition of prosodic features, and correlations between repetition and phonology, grammar, and vocabulary, were explored.

Result: Children with DLD performed below controls on repetition of prosodic features of words and non-words. Repetition of stress and tonal word accent was not correlated with phonological production or receptive vocabulary, but a significant correlation was found between stress repetition in words and expressive grammar.

Conclusion: Repetition of stress and tonal word accents is challenging for children with DLD acquiring Swedish as their first language, but may not be a good indicator of general language ability. Prosody should be taken into account when interpreting results from clinically used word repetition (WR) and non-word repetition (NWR) tasks.
