Do sung speech and background noise affect sentence repetition in dyslexia?

Developmental dyslexia (DD) is typically associated with slow and laborious reading, but there is also evidence pointing to speech-in-noise perception difficulties and a deficit in rapid stimulus processing. We looked at sentence repetition in 56 adult participants, half of whom had a diagnosis of DD, using a mixed design with one between-subjects variable (group) and three within-subjects variables (presentation,...

Findings are preliminary; audiologists assessing patients with dyslexia may find it useful to consider speech-in-noise testing as part of a broader auditory processing evaluation, though current evidence does not yet support a specific protocol change.

Understanding how dyslexia intersects with auditory processing and speech-in-noise perception could refine diagnostic approaches for (central) auditory processing disorder and guide collaborative referral between audiologists and speech-language pathologists.

1. 01Study published in Cognitive Processing (2026) investigates sentence repetition in dyslexia under sung-speech and noisy conditions.
2. 02Links speech-in-noise perception deficits in dyslexia to rapid auditory processing difficulties.
3. 03Sung speech was used as an experimental condition to probe phonological and temporal processing.
4. 04Findings may have implications for auditory processing disorder (APD) differential diagnosis.
5. 05Sample size and full methodology not reported in the available abstract.
