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.
