"VO" stands for "Voice Over," a technique used in various media where a voice is recorded and played back to convey information or narration. It is commonly found in films, television shows, commercials, and video games, providing context or enhancing storytelling. In the production process, a voice actor records the VO in a studio, often using a microphone and soundproofing equipment. The recorded audio is then edited and synchronized with visuals, allowing the audience to engage more deeply with the content. This technique is essential for creating immersive experiences in film, animation, and advertising.
