Acoustic Analysis of Spatiotemporal Variability in Children With Childhood Apraxia of Speech.
Purpose: The purpose of this study was to investigate acoustic spatiotemporal variability in children with childhood apraxia of speech (CAS) compared to children with typical development (TD). Increased spatiotemporal variability in children with CAS relative to nonapraxic peers has been documented...

Increased spatiotemporal variability in children with CAS relative to nonapraxic peers has been documented in multiple kinematic studies. To date, few studies have investigated spatiotemporal variability in CAS using an acoustic signal. Method: Data were drawn from 10 children with CAS and 10 children with TD, ranging in age from 5;0 to 11;2 (years;months), who participated in an online study. All children with CAS had a verified diagnosis and showed at least five CAS features across at least two tasks, independently confirmed by two speech-language pathologists with expertise in CAS. Children repeated the sentences "Buy Bobby a puppy" (BBAP) and "Mom pets the puppy" (MPP) 10 times each. The acoustic spatiotemporal index (STI), calculated from the amplitude envelope, was used to investigate acoustic spatiotemporal variability. Using a regression analysis, we analyzed group differences in STI values while controlling for age and gender. Results: Children with CAS did not produce enough usable tokens of BBAP to analyze. MPP revealed significantly higher acoustic STI values in children with CAS compared to children with TD. No significant effects were observed for age or gender. Acoustic data collected online without the use of specialized equipment yielded high-quality audio data from which amplitude envelope tracing could be reliably accomplished. Conclusions: This study adds to a growing body of empirical data indicating that children with CAS produce speech with more variable spatiotemporal control compared to children with TD. In addition to producing more variable speech, children with CAS were less consistently able to form productions free of phonetic errors. These findings also demonstrate the feasibility of using remote data collection to investigate acoustic spatiotemporal variability, which allows for the recruitment of larger samples of low-incidence populations. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
