Abstract
Introduction
Digital approaches to articulation assessment are increasingly proposed to expand access to speech-language evaluation, yet the comparability of speech performance elicited by digital and conventional word lists across age groups remains insufficiently understood.
Methods
This study assessed age-specific agreement between Hi-DongDong word list, a novel digital articulation assessment instrument, and the Urimal Test of Articulation and Phonology 2 (UTAP-2), the standard reference in South Korea, in 505 typically developing Korean children aged 2-13 years. Each child's audio recordings were scored by three independent speech-language pathologists on both instruments. Agreement for consonant accuracy measures-Percentage of Consonants Correct (PCC), its revised form, and their totals-and for whole-word correctness was evaluated using intraclass correlation coefficients (ICC), Bland-Altman bias and limits of agreement (LoA), and linear mixed-effects models.
