The voice in your ad, explainer video or phone menu is often the first real “person” your audience meets. A well-chosen voice builds trust in seconds; a poorly matched one makes even a great script sound wrong. The good news: choosing a voice actor is not a matter of luck. It is a process you can follow.
Key takeaways
- Start with a written brief: audience, tone, length, language and where the audio will be used.
- Judge demos for range and fit, not just for a “nice voice”.
- Run a short custom audition with a real excerpt of your script.
- Agree on usage rights, revisions and delivery format before recording.
1. Define the audience before you define the voice
Every casting decision starts with one question: who is listening? A voice that works for a youth-oriented mobile app will feel out of place in a bank’s customer service line. Write down:
- Audience: age range, region, professional or general public.
- Purpose: sell, explain, train, guide or entertain.
- Feeling: what should listeners feel after 10 seconds — reassured, energised, curious?
These three answers already narrow the field more than any voice catalogue filter.
2. Translate your brand into voice characteristics
Brand guidelines describe colours and fonts; few describe sound. Turn your brand personality into concrete voice attributes:
| Brand personality | Voice characteristics to look for |
|---|---|
| Premium, trustworthy | Calm pace, warm mid-to-low register, precise diction |
| Friendly, everyday | Conversational, natural smile in the voice, relaxed rhythm |
| Energetic, youthful | Brighter tone, faster pace, dynamic emphasis |
| Expert, technical | Clear articulation, steady pace, authoritative but not cold |
Gender and age are only part of the picture. Pace, warmth, texture and how naturally a voice performs conversational reads usually matter more.
3. Match the voice to the format
Different formats demand different skills, and strong voice actors often specialise:
- Commercials (TV, radio, online): timing to the exact second, strong emphasis on the brand and call to action.
- Explainer and corporate videos: clarity and a steady, engaging pace over two to five minutes.
- E-learning and audiobooks: stamina and consistency across long scripts, without sounding monotonous.
- IVR and phone systems: neutral, clear and easy to understand on low-quality phone audio.
- Animation and games: character work, acting range and the ability to take direction quickly.
Ask to hear samples in the same format as your project. A great commercial voice is not automatically a great e-learning narrator.
4. Listen to demos the right way
A demo reel shows a voice actor at their best, so listen critically:
- Listen on the device your audience will use — phone speakers, laptop, car audio.
- Check range: can the same voice sound warm in one clip and authoritative in another?
- Notice diction and pronunciation, especially for brand names, numbers and foreign terms.
- Listen for audio quality. Background noise, echo or harshness suggest the recording setup may not meet broadcast standards.
Shortlist three to five voices. More than that makes comparison harder, not easier.
5. Run a short custom audition
Demos are generic; your script is not. Ask shortlisted voices to record a 30–60 second excerpt of your actual script. Include the trickiest part: brand name, a technical term, the call to action.
Give every candidate the same short direction, for example: “Warm and confident, as if recommending this to a colleague.” Then compare the auditions blind, with the team members who will approve the final result.
6. Clarify rights, revisions and delivery up front
Most misunderstandings in voiceover projects are not about the voice — they are about the agreement. Before recording, confirm:
- Usage rights: where the audio will be used (online, TV, radio, internal), in which territory and for how long.
- Revisions: how many pickups are included if the script changes or a word needs a different emphasis.
- Delivery format: for example WAV 48 kHz / 24-bit for video, MP3 for web previews, separate files per paragraph for e-learning.
- Deadline: standard and rush turnaround times.
We cover how each of these affects the budget in our voiceover pricing guide.
7. Direct the session — even remotely
Many voiceover sessions are now recorded remotely, with the client listening live. A good session needs:
- A final, approved script (see how to prepare a voiceover script).
- Reference material: the video edit, a mood reference or an example of the tone you want.
- One decision-maker giving direction, so the voice actor does not receive conflicting notes.
Common mistakes to avoid
- Choosing by personal taste alone. The right voice is the one your audience responds to.
- Skipping the audition for long or high-visibility projects.
- Changing the script after recording without budgeting for pickups.
- Forgetting localisation. If the same campaign runs in several languages, plan the voices together so the brand sounds consistent — see dubbing vs. voiceover vs. subtitles.
Final checklist
- ✓ Written brief with audience, purpose and tone
- ✓ Format-specific demos reviewed on real devices
- ✓ 30–60 second custom audition from three to five voices
- ✓ Usage rights, revisions and delivery format agreed in writing
- ✓ Final script, references and one person directing the session
A structured casting process takes a few extra hours at the start and saves days of re-recording later. Your audience may never consciously notice a perfectly chosen voice — but they will notice the wrong one.
