Real-time captioning
Also known as: live captioning, instant captioning
A synonym for live captioning — captions produced and displayed during the event, not afterwards.
The term 'real-time captioning' is used interchangeably with 'live captioning' in most industry contexts. Both describe captions produced during the event with low latency (1.5-3 seconds typical end-to-end).
The term distinguishes the work from post-production captioning, where captions are added to a recording after the event has ended.
