Supplemental Material S2. Group and individual data for all variables.

Supplemental Material S3. Detailed information about individual children, including precise p values and effect sizes with 95% credible intervals.

"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)."
