Everything is branch-scoped over the ConvAI REST API (host https://api.elevenlabs.io, header xi-api-key: $API_KEY). You need $AGENT_ID and $BRANCH_ID.
1. Read the current turn settings
Read the agent's conversation_config.turn (and the workflow nodes if the question is workflow-specific) with GET /v1/convai/agents/$AGENT_ID?branch_id=$BRANCH_ID. Do not pull the full agent context for procedures and unrelated config; the turn block is what matters here.
2. Explain the relevant levers
Based on the user's specific latency or turn-taking question:
- Speculative turn (
speculative_turn): when enabled, the agent starts preparing the LLM response during silence before full turn confidence is reached, reducing perceived latency. - Turn eagerness (
turn_eagerness): controls how quickly the agent jumps in (low, standard, high / eager). - Turn timeout (
turn_timeout): maximum wait time before the agent re-engages.
3. Apply the change
Use a single-field partial-merge patch with the exact dotted path so you touch only the setting in question:
PATCH /v1/convai/agents/$AGENT_ID?branch_id=$BRANCH_IDwith{"conversation_config":{"turn":{"speculative_turn":true}}}, or the same shape forturn_eagerness/turn_timeout.
This commits to branch HEAD and returns a new version. Confirm the change to the user, and note it is on the branch until merged.
