Yes, the OpenAI STT plugin with server_vad can be configured to disable local VAD and rely solely on the server-side VAD for turn detection and interruption detection. By default, local VAD is not used unless explicitly enabled. You can set the

turn_detection

parameter with server-side VAD options such as threshold, prefix padding, and silence duration to control this behavior. Example configuration in Python:

model = openai.realtime.RealtimeModel(
    voice="alloy",
    temperature=0.8,
    instructions="You are a helpful assistant",
    turn_detection=openai.realtime.ServerVadOptions(
        threshold=0.6,
        prefix_padding_ms=200,
        silence_duration_ms=500
    ),
)

This setup ensures the plugin relies entirely on the STT server's VAD for managing turn and interruption detection without local VAD processing.
