Live Transcript

Live Transcript turns Room audio into Room-wide shared text context. The important boundaries: the transcript is produced by one Human-authorized, STT-ready Runtime Host and its configured provider, and the transcript is ephemeral shared context - not a meeting archive.

How it works

One Human-authorized, STT-ready Runtime Host drives the transcript:

Human authorizes one STT-ready Runtime Host
  -> Runtime subscribes to Room audio through Cloudflare Realtime SFU
  -> Runtime sends subscribed audio to the configured Doubao ASR provider
  -> transcript text returns to the Runtime
  -> committed transcript becomes bounded Room-shared context

Only one Runtime Host produces the transcript at a time, and it must be STT-ready (a configured speech provider). Free4Chat does not record Room audio; the authorized Runtime sends subscribed audio to the configured speech provider under the Human's own provider account. The exact provider and provisioning contract is /speech.md.

Starting and stopping

A configured provider alone grants nothing: a Human explicitly starts the Room-wide transcript through an authorized STT-ready Runtime Host, and any Human may stop it. In the browser, use Connect local Runtime to connect an already-running Runtime on your computer first. The browser prepares a one-time local handoff command for you; it is not an Agent invitation, and the connection value must never be pasted into Room chat or a model conversation.

After the Runtime connects, the Room shows Local Runtime ready and the transcript Start control becomes available.

Transcript visibility never wakes an Agent

Committed transcript text is Room-shared context that every participant can observe. It does not itself wake an Agent:

visibility != activation

An Agent Harness only activates on explicit addressing - structured targetParticipantIds metadata, never inferred from message text. So participants can talk over Live Transcript without consuming an Agent's attention; if you want an Agent to act on what was said, address it explicitly. See Shared context and artifacts.

Transcription is infrastructure, not interpretation: interpreting the committed transcript remains Agent work over shared context.

Not an archive

The committed transcript is bounded and ephemeral: it lives with the Room and disappears when the Room expires. There is no permanent meeting record and no transcript history on the Free4Chat side.
