Live Captioning

The process of converting spoken language into text displayed in real time, enabling Deaf and hard of hearing individuals to follow live audio content such as meetings, lectures, broadcasts, and events. Live captioning may be performed by human stenographers (CART providers), automatic speech recognition (ASR) systems, or a combination of both. Unlike pre-recorded captions, live captions must be generated with minimal delay, which introduces challenges around accuracy, latency, and readability — particularly in conversational or multi-speaker settings.
