03/06/2026, 11:49 AMturn_detection mode mid-task. Turn detection is set when creating the AgentSession and isn’t designed for runtime switching.
• To get the behavior you want during a task, start the session with manual turn control and then use the session APIs to manage turns and audio during the task.
What you can do now
1. Use manual turn detection from session initialization
◦ Construct the agent session with turn_detection="manual". This disables automatic turn detection and gives you explicit control over when user/agent turns begin and end.
◦ Then call methods like session.commit_user_turn() when you want to end a user turn and let the agent continue, or call the equivalent session methods to commit agent turns.
1. Suppress listening during a task
◦ If your goal is to prevent the agent from auto-detecting audio while a task runs, you can programmatically disable audio input temporarily with the input API, e.g. session.input.set_audio_enabled(False) to stop listening, then re-enable it when ready. This prevents new audio from triggering turn detection.
Why this approach
• The turn_detection parameter is intended to be chosen at session creation so the agent runtime knows whether to expect automatic VAD/STT or manual control.
• Manual mode plus explicit audio/input control gives you predictable behavior inside tasks without relying on a runtime toggle.
If you want, tell me:
• Which agent type and SDK/language you’re using (web, Python, Node, etc.), and
• Whether you prefer to disable automatic detection only for short sections of a task or for the entire task lifecycle.
I can then give exact code snippets and the specific session/API calls to use.
