Key standards

Visual physical commonsense (V-PC)

  • The car interior is visibly plausible with the windows rolled down, and the person is visibly speaking at normal volume.

Audio physical commonsense (A-PC)

  • The wind noise is substantially louder than the voice and completely covers the voice.

Cross-modal physical commonsense (AV-PC)

  • During the visible speaking while the windows are down, no voice is intelligibly audible above the wind noise.
