Differential impact of acoustic features on vocal emotion recognition between the preoperative, post-operative, and HC groups, after controlling for participant effect, excess zero pattern, and main effects of group and acoustic feature, as well as the effects of the remaining Group × Acoustic feature interactions.

	Post-op vs HC		Post-op vs Pre-op		Pre-op vs HC
	Stat. value	p-value	Stat. value	p-value	Stat. value	p-value
Happiness on Fear scale – duration	−2.41	.02*	−2.23	.02*	.74	.4
Happiness on Fear scale – max. loudness	2.16	.03	3.57	<.01*	.79	.4
Happiness on Sadness scale – max. F0	−2.58	<.01*	−4.09	<.001*	−.96	.3
Sadness on Happiness scale – mean F0	−2.64	<.01*	−2.78	<.01*	.48	.6
Sadness on Happiness scale – min. F0	2	.04	2.69	<.01*	.19	.8

F0 = fundamental frequency; HC = healthy controls; max. = maximum; min. = minimum; Post-op = post-operative group; Pre-op = preoperative group; Stat. value = statistical value.
