Table 2.
Performance values for all listener groups across listening conditions (electric-only or electric-acoustic) with unaltered or F0-flattened phrases. Data columns contain mean intelligibility (% words correct and standard error), the proportions of types of LBEs (insertions or deletions, before strong or before weak syllables), and the total number of LBEs per condition. The final two columns contain p-values for the χ2 analyses conducted on each condition LBE pool, and differences between distributions derived from F0-flattened stimuli relative to unaltered for each condition.
