Table 2. Speaker-averaged paired comparison of front vs. non-front vocalic contexts (n=7)

Measure (mel)	Front M	Non-front M	Mean diff.	Paired t(6)	p (Holm)	Exact perm. p
F2std	1,041.5	963.8	77.7	3.365	.061	.016*
F1std	696.1	609.8	86.3	2.895	.083	.016*
F2off	1,180.4	1,080.8	99.6	1.714	.275	.156
F1off	677.2	604.2	72.9	1.687	.275	.125

Hotelling's paired T²=58.283, F(4,3)=7.285, p=.067. Exact permutation p based on n=7 exact sign-flip test (2⁷=128 permutations).
*p < .05 (uncorrected exact test); no measure survives Holm correction.
