vocametrix_calculate_sz_ratio
Calculate the S/Z phonation ratio from separate /s/ and /z/ recordings to screen for vocal fold pathology when ratio exceeds 1.4.
Instructions
Calculate the S/Z phonation ratio (duration of sustained /s/ vs /z/). Normal ratio ≈ 1.0. Ratio > 1.4 suggests vocal fold pathology (the /z/ is shorter). Requires two separate recordings: one of sustained /s/ and one of sustained /z/.
