Study Design for a Feasibility Exploration of Audio & Video Derived Digital Biomarkers as Reader Comprehension and Engagement Measures of Informed Consent
Aim: Assess the utility of audio and video digital biomarkers as measures of prosody observed while reading passages aloud.
- In this study we collected audio and visual recordings on a phone-based platform while subjects read aloud written text (both a standard paragraph and excerpts from informed consent forms).
- We explored whether specific digital biomarkers extracted from these data exhibit potential for assessing reading comprehension and/or engagement with the written text.
- In this poster we present initial data examining spoken word duration and formant analyses when certain words are presented in different visual-cue contexts in the standard Caterpillar passage.
