In the expository tasks, the mean within-participant correlation between the speech features and themselves was similarly high for the MCI group ( r : mean 0.6101, SD 0.3679) but lower for the cognitively intact group ( r : mean 0.4971, SD 0.3586), although this between-group difference did not reach statistical significance ( t 30 =1.363; P =.18; 95% CI −0.09 to 0.45).
