Voice over talents often specialize in a specific style of voice over, like radio scripts, TV ads or corporate and business voice-over scripts. As outlined by James R. Alburger, author of the book "The Art of Voice Acting: The Craft and Business of Performing for Voice Over", most people only think about commercials when they hear the phrase "voice-over scripts." Today, voice over scripts are used for not just tv and radio commercials. Voice overs are a vital part of giving presentations for media, the net, corporate marketing materials, and to advertise certain activities. There are various categories of voice-over artists, and every role requires quite distinct narration and on-the-air conversational skills.

In the radio industry, voice over talents are widely used to create advertisements, promotional materials, in addition to radio DJ clips. For TV, voiceovers are used for news clips, ads, promo clips and on-air segments introducing news anchors and other TV hosts. The promotions department of a TV station usually deals with the actual on-air promotions of voice-over tracks.

In the corporate community, voice overs are commonly utilized to produce instruction materials, web presentations and promotional videos. Voiceovers can also be utilized to produce marketing and advertising presentations, video demonstrations for industry events, exhibitions, and for training purposes. In some instances, a voice-over artist is used to produce a compilation of telephone information scripts or narrate the voice-over prompts for inbound callers. Stores usually make voice over scripts to announce in-store offers.

In the movie industry, voice overs are utilized to introduce a new segment, or to provide narration. Voice-over talents hired to do this kind of work generally have experience working with movies as well as cartoons, and may have to alter their style to be able to perform a particular character.

Other in-demand areas for voice over talents includes the making of audiobooks, on-line streaming audio tracks and internet media presentations. These are all rapidly growing areas of the web that need a professional voice to support the programming, and voice-over talents that are chosen for these assignments will often have professional voice-over training.
