Feature details

Better captions for the words automatic systems often miss

Live event content often includes terms that are hard for generic transcription systems to recognize. Custom dictionaries give teams a practical way to prepare important vocabulary before the session starts, so the captioning workflow has more context for specialized language.

  • Technical terminology

    Add product names, medical terms, academic vocabulary, industry phrases, and other specialized words before the event.

  • Names and proper nouns

    Help captions handle speaker names, company names, venue names, sponsor names, and branded terms more reliably.

  • Repeatable event preparation

    Prepare vocabulary for recurring events, courses, conferences, and internal programs where the same terms appear often.

In practice

How teams use this feature

  1. 01

    During event preparation, teams collect the speaker names, sponsor names, acronyms, product language, and technical terms that are likely to appear in the session.

  2. 02

    That vocabulary can be added before the caption room goes live, giving the captioning workflow more context for the language that matters most.

  3. 03

    For recurring courses, conferences, and internal programs, dictionaries make it easier to reuse prepared terminology instead of starting from scratch every time.
