Means across listeners in experiments 1A (F₂-matched precursors) and 1B (tilt-matched precursors) of standardized logistic regression weights for F₂ and tilt at each precursor duration (standard errors in parentheses). Mean F₂ and tilt weights and standard errors for vowel targets in isolation were 1.94 (0.15) and 0.47 (0.08), respectively.
