Voice-over talents usually concentrate on a certain style of voice over, such as radio scripts, TV advertisements or corporate voice over scripts. According to James R. Alburger, author of "The Art of Voice Acting: The Craft and Business of Performing for Voice Over", the majority of people mainly think about ads when they hear the phrase "voice over scripts." Today, voice over scripts are used for not just tv and radio ads. Voice overs have become an indispensable part of giving presentations for media, the internet, corporate and business promotional materials, and also to advertise certain events. There are various types of voice-over artists, and every role demands rather distinct narration and broadcast speaking skills.

In the radio industry, voice-over talents are used to produce commercials, promotional materials, in addition to radio DJ segments. For television, voice overs are used for news segments, advertisements, promo videos and on-air segments to introduce news anchors and other TV celebrities. The marketing promotions unit of the television station as a rule manages the on-air promotions of voice-over tracks.

In the corporate and business community, voiceovers are generally used to come up with training materials, internet presentations as well as promotional clips. Voice overs may also be used to create sales and marketing presentations, video clip presentations intended for industry events, conferences, and for coaching purposes. In some instances, a voice-over talent can be used to create a compilation of telephone information scripts or narrate the voice-over prompts for inbound callers. Retail stores may make voice over scripts to be able to announce in-store promos.
