Video captions are essential for ensuring accessibility to students with hearing impairments and complying with accessibility standards set by the CSU Accessible Technology Initiative and federal law (Section 508). Captions benefit all students by promoting inclusively and equal access to educational resources. They ensure that students, regardless of their hearing abilities, can fully engage with the course material. Captions provide a visual representation of the audio content, making it easier for students to comprehend and retain information. They also help in noisy environments, when English is not the student's first language, or when reviewing content without audio. By having captions available, all students have the opportunity to access the information effectively, enhancing their learning experience.

Automatic Captioning in Kaltura

All videos uploaded to Kaltura receive automatic captioning. If the video was created through a cloud recording in Zoom, it will utilize the Zoom Audio Transcript for captioning. For videos uploaded directly to Kaltura, automatic captioning is provided through Kaltura REACH. However, it's important to note that these automatic captions may not always be accurate.

The Technology Equity and Inclusion (TEIN) department offers a captioning service for videos, however their schedule may not always permit captions to be ready in time for a video to be posted for students.
