Details of the novel Music/Speech AXB tasks.

Modality	Disrupted	Standard stimulus X (Music or Speech)		Comparison stimuli (A,B)
		Filtered: “on the radio” or “behind the door”		Both unfiltered
		Rhythm (durational properties and amplitude modulations)	Pitch (f0) contour
Music	Rhythm only	Pattern of “strong” (longer, louder) and “weak” (shorter, quieter) notes e.g., SSWSS	Flat: one note (A) at 441 Hz	Only one matches X in rhythm
	Pitch only	Series of notes with identical duration and amplitude	Melodious: various notes	Only one matches X in f0 contour
	Rhythm and pitch	Pattern of “strong” (longer, louder) and “weak” (shorter, quieter) notes e.g., SSWSS	Melodious: various notes	Both have melodious pitch contours, but only one matches X in rhythm
Speech	Rhythm only	Syllable string with certain pattern of durational properties and amplitude modulations	Flat: 223 Hz	Only one matches X in rhythm
	Pitch only	Syllable string comprising fully sonorant sounds: no breaks in periodicity, and relatively little amplitude information (excepting the nuclear-accented syllable)	Melodious: intonation pattern with rises and falls	Only one matches X in f0 contour
	Rhythm and pitch	Syllable string with pattern of durational properties and amplitude modulations	Melodious: intonation pattern with rises and falls	Both have melodious pitch contours, but only one matches X in rhythm
