(if yes) Do you create near-as-possible live captions or text alternatives? (AAV13)

Why Is This Important?

Techniques for real time transcription of live audio and video content include stenography (which uses a stenotype machine with a phonetic keyboard, as used by court reporters) and voice captioning (which uses voice recognition software. Such techniques are very expensive and not always accurate, as there is no time for corrections and refinements. Also. with both methods, there is an inevitable delay between the dialogue being spoken and the captions appearing on screen. However, in some cases, transcriptions or captions that are as near-as-possible to the original content may be preferable to other text alternatives.

How To Fix The Problem

Real time transcription of live audio and video requires dedicated equipment and trained human operators. If such services are used, the transcription or captions must appear in real-time, they must be synchronised with the content, and they must appear in the same viewport as the live audio and video content.
