Perceptual Ratings Predict Speech Inversion Articulatory Kinematics in Childhood Speech Sound Disorders.

ABSTRACT:

Purpose

This study evaluated whether articulatory kinematics, inferred by articulatory phonology speech inversion neural networks, aligned with perceptual ratings of /ɹ/ and /s/ in the speech of children with speech sound disorders.

Method

Articulatory phonology vocal tract variables were inferred for 5,961 utterances from 118 children and three adults, aged 2.25-45 years. Perceptual ratings were standardized using the novel 5-point PERCEPT Rating Scale and training protocol. Two research questions examined if the articulatory patterns of inferred vocal tract variables aligned with the perceptual error category for the phones investigated (e.g., tongue tip is more anterior in dentalized /s/ productions than in correct /s/). A third research question examined if gradient PERC
