The primary aim of the current study was to examine the source, content, understandability and actionability of information related to voice disorders in the most widely viewed YouTube videos. The secondary aim was to compare the difference in content, understandability and actionability across the video sources. The terms ‘voice problem’ and ‘voice therapy’ were used to search and identify videos with top views on YouTube. Content of the top 50 most viewed and relevant videos was coded. Each video was rated for understandability and actionability using the Patient Education Materials Assessment Tool for Audiovisual Materials.  The total number of views for the included videos was 54,74,432 and the total length of the videos was 4 hours 48 minutes. There was no significant difference in meta-data including number of views, video length, thumbs-up, and thumbs-down across videos sources. The video content was mainly focusing on signs and symptoms, causes, and vocal hygiene/home remedy. The understandability and actionability were found to be poor, which indicates that these videos may be of little value to consumers in managing their voice disorders. There is a need for developing videos with appropriate and evidence-based content as well as making them more understandable and actionable for self-management of voice disorders.
