TABLE III.

Results from a repeated-measures, two-way ANOVA of average stimulated current (represented as a percentage of the total dynamic range) calculated for voiced frames of speech (averaged across 23 vowels) for ACE and ID-FACE strategies at each of the six acoustic conditions where “sig.” refers to significance, ‘ns’ refers to no significant difference (p > 0.05) and bold type refers to a significance difference of various p-values < 0.05.

Effects of strategy-specific selection patterns: Stimulated current of individual channels (normalized clinical levels)
