Analysis results for error rate, duration, and spectral mean (Maas & Mailend, 2017)
journal contribution
posted on 2017-06-22, 20:05 authored by Edwin Maas, Marja-Liisa MailendSupplemental Material S1. Group means and
standard deviations for error rate, duration median, and m1 median, by target
and timepoint, are provided in a table; analysis results are described, including ANOVA interactions, p values, and significant/not significant effects. Provided figure shows group data for spectral mean, by target and timepoint, for adults vs. TD6 vs. TD9, TD6 vs. SSD6, and TD9 vs. SSD9.
"The focus of this study was on fricative contrast and anticipatory CV coarticulation, as indexed by acoustic measures obtained from the first spectral moment (m1) at three points during the fricative (onset, midpoint, offset). Acoustic measures were based on tokens in which both fricative and vowel were perceptually accurate. Accuracy was judged from audio recordings by a native English listener and verified by the first author (a near-native speaker with 20+ years of phonetic training). Acoustic analyses were performed using Praat (Boersma & Weenink, 2008)."
