Overview

The Caption Vocabulary is a way to enhance the accuracy of your AI-Generated Live Closed Captions (CC) by adding terms that the AI may not be able to easily interpret. These usually are of the form of Names (Places, people, job titles, etc. which may be pertinent to your Streaming needs) and Initialisms (F.B.I., A.C.M.E., etc.).  It can be accessed in the control center here: https://controlcenter.invintusmedia.com/manage/vocab

Note When you Create, Update, or Remove words from the Vocabulary manager page the changes are saved automatically so there is no "Save All Changes" button like some of our other components have.

How To Use

Add a phrase as it should appear in a captions generated from the AI captions. This is useful for naming speakers, job titles or truly unique or rare terms that wouldn't appear in a dictionary.

Examples of good custom vocabulary might be made-up or uniquely spelled words like:

sparkletini, Ginnifer

You should not add terms like e pluribus unum or orthostatic hypotension

Keep in mind that short phrases do better than long phrases so it's advised to keep phrases shorter when possible.
