Primary outcome measure(s)
Speech intelligibility as assessed by the Coordinate Response Measure (CRM) Task — Data is collected during the second lab visit for each participant, approximately 2 weeks after study enrollment. The duration of the study visit including testing is approximately 2.5 hours. During the CRM task (Bolia et al., 2000), participants are presented with a phrase detailing the following identifiers: target, color, and digit.
They must listen for a target name and respond with the corresponding color and digit. Speech intelligibility performance is assessed based on accuracy, or percent correct across all trials conducted in a given condition.
