  • Overflow video on attendee devices and managed large screens.
  • Custom text overlays for production graphics and displays.
  • Speaker labels for supported input-language configurations.
  • Downloadable transcripts at room and event level.
  • Terminology dictionaries for names, acronyms, and specialized language.

Core concepts

Section titled “Core concepts”

Event

Section titled “Event”

An Event is the top-level production. It contains branding, assigned Event Producers, an event dictionary, transcripts, and one or more Rooms.

Room

Section titled “Room”

A Room represents a live session destination. It defines:

  • Input and audience languages.
  • Sponsor branding.
  • Mobile, large-screen, and overlay links.
  • Audio and optional video ingest.
  • Attendee defaults for transcription, audio, and video.
  • Room-specific dictionary terms and transcripts.

Stream

Section titled “Stream”

A Stream is one live run inside a Room. The Producer starts it through browser ingest on the Room page. Completed streams are listed under the room and event transcript sections.

reCap by Volo

Section titled “reCap by Volo”

reCap is a companion service that may be included in the same event offering as Volo. Volo produces the completed transcript; the transcript is then sent to reCap, where the session summary is created and hosted for viewing. Summary generation and hosting currently happen outside the Volo application.

Roles

Section titled “Roles”
  • Administrator creates events and rooms and controls Producer assignments.
  • Event Producer configures assigned events and rooms, prepares audience access, and operates streams.
  • Attendee joins through a QR code or link without creating an account.

See Roles and permissions for the detailed boundary.

Content flow

Section titled “Content flow”

Volo produces captions, translated text, assistive audio, live video, audience experiences, and downloadable transcripts.
