		t	p	Qualitative explanation
Rough—smooth	f0 mean	2.63	0.009	Higher f0, smoother
	Pitch range	2.30	0.022	Larger range, smoother
	LTF2	4.30	<0.001	Higher LTF2, smoother
	Spectral tilt	5.18	<0.001	Steeper tilt, smoother
High complexity—low complexity	f0 mean	−3.02	0.003	Higher f0, more complex
	Pitch range	4.33	<0.001	Smaller range, more complex
	LTF2	−2.13	0.034	Higher LTF2, more complex
	Spectral tilt	7.11	<0.001	Shallower tilt, more complex
	Group (syn vs. con)	−2.40	0.016	Synesthetes more complex
	Group (syn vs. phon)	−2.46	0.014	Synesthetes more complex
Repetitive—non-repetitive	f0 mean	4.40	<0.001	Higher f0, less repetitive
	Pitch range	−2.48	0.013	Smaller range, less repetitive
	LTF2	5.93	<0.001	Higher LTF2, less repetitive
Line-like—blob-like	Spectral tilt	3.61	<0.001	Steeper tilt, more blob-like
