A voiceover is the voice you hear but do not see. It narrates commercials, explains products, and guides viewers through a story. Some voiceovers are warm and conversational. Others are deep and authoritative, the classic movie trailer sound.

The right voice changes everything. The same script read by two different actors can feel friendly or menacing, premium or cheap. Casting directors audition dozens of voices to find the match.

Where voiceovers appear

• Television and radio commercials
• Explainer and product videos
• Documentaries and corporate films
• Audio ads on streaming platforms

Synthetic voices improved dramatically in recent years and now handle many routine jobs. For brand work that needs warmth or nuance, human performers still dominate. The subtleties of timing and emotion remain hard to replicate.
