Post hoc tests on the naturalness scores for different method pairs. Bold p value indicates statistical significance.

Method (Average)	MSR (0.15)	GUM (0.14)	NPEA (0.52)	FHRPHS (0.30)	NPIE-MLLS (0.67)
MSR (0.15)	-	p=1.000	p<0.001	p<0.001	p<0.001
GUM (0.14)		-	p<0.001	p<0.001	p<0.001
NPEA (0.52)			-	p<0.001	p<0.001
FHRPHS (0.30)				-	p<0.001
