There is a overlap between where a sound is coming from and where we see the source of the sound. Vision and hearing seem to go hand in hand where you hear a sound you see the cause of that sound, but their are instances where that does not hold true, our vision and hearing provide a discrepant information. One example of visual capture is known as the "ventriloquism effect," which refers to the perception of speech sounds as coming from a direction other than their true direction, due to the influence of visual stimuli from an apparent speaker. Thus, when the ventriloquism illusion occurs, the speaker's voice is visually captured at the location of the dummy's moving mouth (rather than the speaker's carefully unmoving mouth).
