Avoid costly re-shoots. Get 5 practical insights to help you choose the right voice for your documentary.
A documentary needs a completely different approach behind the microphone than a fifteen-second radio advert. If a voice actor uses too much energy or ends every sentence with an upward intonation, viewers quickly switch off. A voice that tries too hard is like someone shouting through a megaphone in a quiet museum square. It draws attention to the speaker instead of the subject on screen.
For a long narrative, you need a voice that conveys calm and draws the viewer in without being pushy.
A deep or warm voice is a bonus. But a professional documentary voice-over mainly needs insight into the content. The voice actor must understand when a sentence carries significant meaning and when a paragraph simply serves as a transition.
Experienced Belgian voices like Veerle, with over 25 years in the field, know exactly how to pace a long text. When selecting voices, look for these qualities:
For a Belgian audience, a Dutch voice often sounds too distant in a documentary. The accent and intonation subtly influence the viewer's experience. For a Flemish project, choose a voice with a natural Flemish accent. A French-speaking Belgian production often benefits from a voice like Bernard's, who understands the nuances of Belgian French.
Always listen to a demo track recorded specifically for a documentary or corporate video. A voice that sounds excellent in a fast-paced commercial can quickly become monotonous in a long narrative.
In a documentary, the silence between sentences is just as important as the spoken words. As a director, you often see mistakes when the voice-over is recorded too tightly against the visual edit.
Director's tip: have the voice actor take deliberate pauses before impactful passages. In documentaries, the real impact often comes from the silence just after a statement. During recording, instruct them to let sentences settle. An experienced voice actor dares to wait until the visuals allow for it.
For commercial productions, a basic fee is used, plus a buy-out for the medium and duration. For a documentary or non-commercial project, the structure is different. Here, payment is usually calculated based on the total word count or a fixed project rate.
If a documentary later appears on television or in cinemas, the usage rights change. By clarifying this with the voice actor or agency beforehand, you avoid financial surprises if the project reaches a wider audience than planned.
Loading demos…
In a documentary, the pace is slower than in a corporate video or commercial. You can expect an average of 110 to 130 words per minute. This gives the viewer enough time to absorb the visuals.### Can you hear a voice before the final recording? Yes, you can listen to existing demos from our portfolio of 94 professional voices. On request, a voice actor can also record a short sample of your script to help you test the tone.
Small script adjustments can be re-recorded later. To avoid extra costs, it's best to finalise your text before we record, ideally once your video editing is set.
