Comparisons of phonological and phonetic characteristics of the test sentences across the two experimental conditions.

Sentence characteristics	High-sonority (mean)	Low-sonority (mean)	Results of t-tests
Sonority index	6.21	4.54	t(9.6) = 8.4, p < .001
% Sonorous	81.63	60.02	t(9.1) = 3.2, p = .01
Speech rate (syll/sec)	3.47	3.96	t(5.98) = -1.7, p = .14
Pitch variability (st)	1.81	1.79	t(7.3) = 0.1, p = .96
Mean syllabic energy rise (dB)	8.09	15.48	t(7.0) = 5.2, p < .01
Mean amplitude inter-trough interval (ms)	274.40	260.92	t(7.9) = 1.3, p = .24
Variability of amplitude inter-trough intervals (CV)	0.32	0.19	t(5.5) = 2.8, p < .05
