Noise VAD

simple VAD plugin extracted from the old ovos-listener

should only be used as fallback, works in all platforms including 32bit systems

Configuration

{
    "listener": {
        "VAD": {
            "module": "ovos-vad-plugin-noise",
            "ovos-vad-plugin-noise": {
                "method": "all",
                "max_current_ratio_threshold": 2.0,
                "energy_threshold": 1000.0
            }
        }
    }
}

Arguments

max_energy: Optional[float] = None
    Maximum denoise energy value (None for dynamic setting from observed audio)

max_current_ratio_threshold: Optional[float] = 2.0
    Ratio of max/current energy below which audio is considered speech

energy_threshold: Optional[float] = None
    Energy threshold above which audio is considered speech (None for dynamic setting from observed audio)

silence_method: SilenceMethod = "all"
    Method for deciding if an audio chunk contains silence or speech

Methods

RATIO
  Only use max/current energy ratio threshold

THRESHOLD
  Only use current energy threshold

ALL
  max/current energy ratio, and current energy threshold
