Lecture Captioning

The real-time or post-production conversion of spoken lecture content into text, displayed to students during or after a class session. Lecture captioning can be performed by human captioners (such as CART providers), by automatic speech recognition software, or by a combination of both. It serves students who are deaf or hard of hearing, those with learning disabilities, English language learners, and increasingly all students who benefit from multimodal access to content. Modern implementations typically use cloud-based speech recognition integrated into video conferencing or lecture capture platforms, though accuracy for spontaneous academic speech with specialised terminology remains a challenge.
