Results from the linear discriminant analysis (LDA) with all variables and all participants included. Variables with negative weights indicate that a higher score on that variable is predictive of AOS diagnosis (according to the Apraxia of Speech Rating Scale [ASRS]). Variables with positive weights indicate that a higher score on that variable was not associated with AOS diagnosis. AOS = apraxia of speech; nPVI-V = normalized Pairwise Variability Index–Vowels; VOT-SD = standard deviation of voice onset time.
