People in the advertising, audio, video-gaming, audio-visual and educational industries throw about the term “voice over” frequently. For those new to the industry, or coming across the term for the first time, having a clear definition of what voice over is, or more importantly, is not, is critical.

A simple definition of voice over is recorded speech when you can’t see the speaker.

But what does that actually mean?

And what does it look like in practical terms?

Voice over definition: What is it?

Let’s take a look at three different dictionary definitions of voice over.

The  Oxford Dictionary defines a voice over as

“A piece of narration in a movie or broadcast, not accompanied by an image of the speaker.”

The Cambridge Dictionary definition is

“on a television programme, film, or advertisement, the spoken words of a person that you cannot see”.

The definition in the Merriam-Webster dictionary lists voice over as

“1a : the voice of an unseen narrator speaking (as in a motion picture or television commercial) b: the voice of a visible character (as in a motion picture) expressing unspoken thoughts 2: a recording of a voice-over”.

The common thread with these definitions is narration, spoken words or voice in the absence of the visual image of someone actually speaking.

A voice over can occur in conjunction with an image, either still or moving, or as audio-only. An example of this would be a radio ad, either live or recorded.

And what is it not?

A voice over is not when moving images of somebody speaking accompany the spoken words, narration or voice with the intent to synchronize these mediums. The term for this is dubbing, and an in-depth look at how voice overs and dubbing are different can be found here.

A voice over is also not a real-time recording of narration, spoken words or voice with the live image of the person speaking. The term for this would be video recording with audio.

If the speaker (or supposed speaker) and voice are on screen at the same time, it’s not a voice over – even if the speaker happens to be off-camera. If the audio is playing over the moving or still images, or is playing independently of any images at all, it is a voice over.

Voice overs in action

Looking at when voice overs occur makes understanding the definition of voice over easier. Some of these are:

  • Characterization
  • As a creative device
  • Education & training
  • Information & entertainment
  • As a commercial device
  • Translation

Let’s look at these situations in more detail.

voiceover definition what it means


This is possibly the most well-known form of voice over, although people may not realize that’s what it is. Using voice over as characterization is when a human voice is played over animations or fictional characters (e.g. talking animals in a film). Anyone who has watched a cartoon on television or film has experienced voice over as a charter device first hand.

By lending the animation or fictional character a human voice, the personality of that character comes to life as they engage with the narrative.

A creative device

Leading on from characterization, voice over can also be used as a creative device in films, television, theatre, and radio. In these situations, the voice over may take the form of an omniscient narrator (a narrator that is external to the story), a character reflecting on his or her past, or ‘extra’ characters that enhance the existing dialogue (e.g. a studio audience for a radio talk-back show).

Voice overs used in this context may be in sync with any corresponding images. More often than not, however, they have only a loose connection with the images displayed on screen. They can also be used in summaries that bridge gaps within a production or story.

Education & training

Voice overs are frequently used in education & training, online or face-to-face. The voice over may take the form of audio-only, as if the speaker were giving a lecture. It also may occur in conjunction with visual aids, such as printed material, PowerPoint presentations or video clips.

Many online tutorials use voice overs to talk listeners through the steps of using a program or software while simultaneously showing those steps on the screen.

Information & entertainment

Documentaries, news & sports broadcasting, and video games also use voice overs. In these situations, the voice over is used to enhance any visual material.

For example, for documentaries and news broadcasting, there may be visual snippets related to the topic in question. The voice over would describe how these images relate to one another and fit within the narrative as a whole.

In addition to this, video games use voice overs to bring characters to life and lend a level of reality to the game. Other uses include explaining rules or sharing information about rewards, challenges, and warnings.

As a commercial device

Advertising has long used voice over as a key tool in developing ads for television, radio, and increasingly, digital platforms. Information about the production, business, brand or event is shared with or without supporting images.

Like for information & entertainment, the images may be snippets of visually relevant material. The supporting image may also simply be a still picture of a brand’s logo and it is the voice over that does the heavy lifting.

Any pre-recorded audio material on radio would be considered a voice-over, as well as ads that are used in streaming services such as Spotify.


Confusion between voice over and dubbing often occurs when it comes to translation. That’s why it’s important to revisit the definition of voice over. A voice over is when the speaker (or intended speaker) cannot be seen. There is no attempt to match the voice up with the image of somebody speaking.

Voice over in translation is when a voice is recorded in a language other than the original film. The recording is then played over the images. This retains context but is not in sync. The volume of the original language audio is muted or turned down. You could think of it as almost-dubbing, but in essence, its voice over.
