Using Captioning Technologies in the Classroom

Captioning technologies can be helpful for everyone to ensure clear communication in the classroom. Caption text is powered by machine learning. It depends on audio input from the speaker, including the speaker’s accent, voice modulation, and intonation. As a result, captions might not be a complete and accurate transcription of the speaker’s words.

Panopto Captions


Panopto is an all-in-one video platform. It not only provides desktop lecture recording and automatic captioning services, It is also seamlessly integrated with Canvas. Panopto allows users to add ASR (Automatic Speech Recognition) Captions into videos they have Creator access to. Note that machine-generated captions clearly aren’t the same as human transcription, so they need to be revised and edited to ensure they are 100% accurate.


You can review our documentation for both the PC (Windows) and Mac (Apple) or attend a workshop to learn more.
