Framework Node

The Framework node is the heart of every Voiceblox flow. It receives all component connections, acts as the entry point for the conversation step chain, and determines the runtime. Every flow must have exactly one Framework node.

Interruption behavior

The interruption_mode parameter controls how the agent handles user speech while it is speaking:

• Off — The agent cannot be interrupted. Useful for scripted announcements or compliance-sensitive flows.
• On — The agent can be interrupted by the user. For cascade agents, this uses adaptive ML-based interruption handling that distinguishes true interruptions from conversational backchanneling (e.g. “uh-huh”, “okay”). For realtime agents, this uses VAD-based interruption detection.
