Why Live Caption With 3Play

How it Works

3Play Media offers a single live caption service, including caption production by machine – Live Automatic Captioning – and caption production by 3Play Voice Writer contractors – Live Professional Captioning. Each type of caption production can be ordered separately; however, Live Professional Captioning includes an auto-failover to Live Automatic Captioning in case of interruption to human-powered captions.

Live Automatic Captioning

Live Automatic Captioning is generated by automatic speech recognition (ASR) technology. While auto-captions have a lower accuracy rate compared to human-powered live captions, they are a great baseline option for increasing accessibility when professional captions are not an option! We recommend Live Automatic Captioning for non-high visibility events and meetings that don’t require professional captioning.

Live Professional Captioning

Live Professional Captioning relies on human captioners. In other words, it’s done by trained professionals! If quality and compliance are important to you when it comes to live captioning, Live Professional Captioning is the right choice for you. We recommend Live Professional Captioning for corporate videos, higher education videos, events, and web streaming.

Schedule Live Captions in Minutes
