TABLE III.
Statistical comparison (based on α = 0.05) between the correlation coefficients of the CSII measure (with sentence intelligibility scores) implemented with various types of segmentation (as reported in Table TABLE I.). Asterisk indicates that the difference in correlation is statistically significant (p < 0.05).
