Overt and covert speech identification. Median identification rank for each subject during overt speech, covert speech, and baseline control conditions (see section Evaluation for more details). At the group level, rank_overt = 0.91 and rank_covert = 0.55 are significantly higher than chance level (0.5; randomization; gray dashed line), whereas rank_baseline = 0.48 is not significantly different.
