Features

  • Low-Latency VAD Heuristics: Operates on sub-frame time slices for immediate interruption handling.

  • Dynamic Endpointing: Automatically balances conversational fluidity against premature turn cutoff.

  • Zero External Dependencies: Pure Python standard library implementation.

    Enables real-time voice agents and streaming audio pipelines to detect conversational turn completion, distinguishing finished speech turns from mid-sentence hesitation pauses using acoustic VAD and semantic scoring. It provides low-latency decision and telemetry output through a native MCP interface for integration with MCP-compliant clients.
