Abstract

Many children with cerebral palsy (CP) present with reduced speech intelligibility due to dysarthria. However, mobility restrictions and geographic distance may limit their access to clinical services, including speech assessment. Online clinical speech services may be a practical solution, if acoustic and perceptual measures collected online are valid. In this study, the speech of children with dysarthria due to CP was recorded simultaneously via 1) Zoom video conference and 2) a professional audio-recording device sent to the family. Acoustic measures (vowel space area and pairwise variability index) and the perceptual measure of ease-of-understanding ratings were examined. All measures showed strong positive correlations between online and audio-device recordings. Therefore, speech assessment using online recordings may be a valid alternative to in-person assessment.
