Books become voices.
Stories stay with you.

Following the invention of the so-called audio picture shortly before the end of the nineteenth century, early records featuring readings by professional voice artists became the classic predecessors of today’s audiobooks. The first recordings explicitly described as audiobooks were produced after the Second World War.

At that time, blind listeners were the main audience. In 1954, the German Institute for the Blind in Marburg opened its first audiobook library for blind people. Changes in recording media shaped the sector’s later development, from records through cassettes to CDs.

To reflect multimedia listening habits, many audiobook releases also include an MP3 version, addressing digital use and different listening preferences. Children are an important audience, while genre preferences are more varied: alongside children’s stories, crime fiction and novels are popular, as are well-known fantasy works such as Harry Potter, supported by cross-promotion.

Production workflow

Alongside an increasingly varied audiobook catalogue, improved sound quality attracts interest in recordings. Thorough planning before production—including a detailed client brief, a precise definition of the audience and careful casting—is crucial to the quality and prospects of the finished audiobook.

Production companies regularly seek suitable audiobook voices. Even if someone is not right for a current project, their details are often retained in a voice database. This database can then support casting for a later production.

After preparation and rehearsals, recording takes place, ideally in a studio with audiobook experience and high-quality equipment. The central participants are the voice artist or artists and the sound engineer; a director, producer or author may also take part.

Editing removes slips, unwanted background noises and excessively long pauses that could detract from listening. Mixing is needed when several voices alternate or when music or special background sounds are required. Final mastering gives the audiobook its finished sound.

Audiobook voices

Alongside a compelling story, choosing the right voice is one of the most decisive factors in a successful audiobook production.

The right match depends on factual and psychological factors. Clear pronunciation is essential and, unless the book specifically calls for something else, delivery should be free of dialect. Professional casting databases therefore commonly feature performers with voice and speech training.

Audiobook voices should usually be pleasant to listen to, with casting suited to the content and intended audience, including the performer’s age and gender where relevant to the role. The ability to adapt delivery to the situation is important: creating vocal tension in a crime story, for example, or a cheerful atmosphere in a children’s book.

This is one reason audiobook producers often include actors in their voice databases. Series also require performers willing to collaborate over a longer period: without a visual component, recognition of the voice becomes particularly important. Some audiobooks include dialogue scenes, where acting ability and an empathetic working relationship between performers can greatly improve the recording.

Sound effects for an authentic atmosphere

An engaging recording may need more than professional audiobook voices. Foley artists are sometimes involved and, together with the sound engineer’s expertise, create an authentic atmosphere. Hoofbeats or the sound of heavy rain can make a story feel real and turn listening into an immersive experience.
