Table A1: Acoustics of the Teaching and Test Words.

Means (and standard deviations) for duration in seconds, pitch maximum (max) in Hz, and pitch mean in Hz, are given for word tokens with each pitch contour from the low-variability and high-variability teaching conditions and the test phase (always low variability). Row 7 (in bold and italics) reports the grand mean across all high-variability teaching tokens.

Variability	Phase	Word	Pitch	Duration (SD)	Pitch max (SD)	Pitch mean (SD)
