What is the role of a voice-over in video production?

The role of a voice-over in video production is to provide a narrative or commentary that is delivered by a speaker who is not visible on-screen. This technique allows filmmakers to convey information, emotions, or insights that enhance the storytelling without requiring the speaker to be physically present in the scene. Voice-overs can be used to develop character backstories, provide context, or guide the audience through the visual content, making it a crucial element for creating a deeper connection with the viewer.

In contrast, background music serves to create mood and atmosphere, while sound effects enhance the realism of the audio environment. Dialogue between onscreen actors refers to the spoken interactions that occur between characters in front of the camera, which differs from the narration aspect of a voice-over. Thus, the specific purpose of a voice-over is to enrich the narrative experience by introducing commentary or narration from an unseen source.
