How to Write a Voice Over Brief That Gets You a Better Read

October 17, 2026 by Leah Arscott

You’ve found the right voice. The script is approved, the files come back fast, and they sound great. Yet something feels slightly off. The read is warm when you pictured bright, or polished when you wanted casual. Now you’re booking pickups, and the deadline is creeping closer.

Most of the time, the problem isn’t the talent. It’s the brief.

I’m Leah Arscott, a Canadian voice actor with seven-plus years in the booth and more than 1,000 projects completed for brands like Google, Amazon, Apple, BMW, Porsche and Sephora. I work with agencies and production houses across North America and Europe, and I’ve read thousands of briefs. The best ones share a few simple habits. These voice over brief tips will help you get the read you’re hearing in your head on the very first take.

Why Voice Over Brief Tips Matter More Than You Think

A voice actor can only perform what they understand. When the direction is clear, a professional voice will usually hit the target quickly. When it’s vague, even great talent has to guess.

Here’s a real example. Recently, I recorded a regional campaign where the brief asked me to match the pacing of the temp track. There was nothing about tone. So I delivered a warm, reflective read that fit the script. After the team cut it against picture and music, they asked for a brighter, more hopeful take with about 50 percent more energy, at the same speed. The second read landed perfectly. However, one sentence about tone in the original brief would have saved a full round of revisions.

That’s the real value of a strong brief. It saves time, protects your budget and keeps your client happy.

The Essentials Every Voice Over Brief Should Include

You don’t need a ten-page document. In fact, the best briefs are often short. They just cover the right things.

The Script, Final and Formatted

Send the final, approved script whenever possible. Format it clearly, with each spot, version or tag labelled. If certain lines are still in legal review, mark them. That way, nobody records a line twice.

Who You’re Talking To

Tell your voice actor who the listener is. “Busy parents in their thirties” or “IT managers comparing software” gives a performer something real to aim at. As a result, the read sounds like it’s speaking to one person, not a crowd.

Tone, in Real Words

This is where most briefs fall short. “Upbeat and friendly” describes half the ads on TV. Instead, describe the feeling you want the listener to have, and include what you don’t want. We’ll dig into this in the next section.

Pacing and Timing

Share the target length, such as 30 seconds or 15 seconds, and whether timing is tight. If you have a temp track or a cut, send it. Also let your talent know if they should match it closely or simply use it as a guide.

Where It Will Run

Media type and usage affect both the performance and the price. A read for a cinema ad feels different from one for paid social. In addition, usage details help your voice actor quote accurately from the start. For more on that, see my guide to commercial voice over rates.

How to Describe Tone So It Actually Translates

Tone is personal, so the words you choose matter. Here are a few approaches that consistently work.

Use Pairs and Opposites

Words on their own can be vague. Pairs make them precise. For example, “confident, not cocky,” “warm, but never sleepy,” or “excited, but grounded.” The second half tells your voice actor exactly where the edge is.

Describe a Real Moment

Paint a quick scene. “She’s telling her best friend about a great find at brunch” is far more useful than “conversational.” Similarly, “a calm nurse explaining next steps” gives a narrator something concrete to play.

Give a Rough Dial

Simple percentages work surprisingly well. “About 30 percent warmer” or “half the energy of the temp” helps a performer adjust in a measurable way. Just pair it with a note about what should stay the same, such as the pacing.

Skip Vague Phrases

Phrases like “make it pop,” “more sparkle” or “just make it better” force your talent to guess. If you’re not sure what’s missing, say so. A good voice actor will offer a few different reads and help you find it.

Reference Spots: The Most Underrated Voice Over Brief Tip

If you only add one thing to your next brief, make it a reference. One or two links to ads you love will tell a voice actor more than a paragraph of adjectives ever could.

The key is to say what you like about each one. For example, “I love the relaxed pace in this one” or “the smile in her voice here is perfect.” Otherwise, your talent may focus on the wrong element.

One quick caution about temp voice over. If your cut uses a temp read, say whether it’s direction or just a placeholder. Many producers love their temp track without realizing it. Sharing that early avoids surprises during the review.

Pronunciations and Details That Save a Re-Record

Small details cause most of the avoidable pickups. Fortunately, they’re easy to cover.

Spell out tricky words phonetically, especially brand names, product names, people and places. If there’s an official pronunciation, a short audio clip or a link to a video of the founder saying it is ideal.

Next, flag how you want numbers, dates and web addresses read. Should it be “twenty twenty-six” or “two thousand twenty-six”? Is it “dot com” or simply the brand name? Should a phone number be grouped a certain way?

Finally, note any legal lines, disclaimers or required speed. A fast legal tag at the end of an automotive or pharma spot is a skill on its own, so it helps to know in advance.

Delivery Specs: Files, Formats and Alternate Takes

Clear delivery specs mean your files arrive ready for the edit. Let your talent know:

The file format you need, such as WAV at 48kHz, 24-bit

Whether you want files raw or lightly edited

How you’d like files named

How many alternate takes you’d like for key lines

Any cutdowns or tags, such as 15-second and 6-second versions

Asking for a couple of alternate reads on the most important line is a smart, low-cost safety net. It gives your editor options without another session.

Should You Direct the Session Live?

Sometimes, a written brief is all you need. Other times, it’s worth joining the session.

Live direction is especially helpful when the client is particular about tone, the script has a lot of brand-specific language, or the spot is high stakes. I work with producers across time zones and connect through Source-Connect, Zoom or phone patch, so you can listen in from anywhere and give notes in real time.

On the other hand, many projects run beautifully with a self-directed read. In that case, a strong brief does the directing for you.

Curious what a self-directed read sounds like? My corporate narration and e-learning demos at leahvoiceover.com were all recorded from written direction.

Common Brief Mistakes That Lead to Retakes

Even experienced teams fall into a few traps. Watch out for these:

Contradictory notes, like “high energy but very calm”

Feedback from several stakeholders who want different things

Script changes after the session without a heads-up

Asking for a voice “exactly like” a celebrity or another brand’s spokesperson

No tone direction at all

Most of these come down to alignment. Before you send the brief, make sure your internal team and your client agree on the direction. That one conversation can save an entire round of revisions.

A Simple Voice Over Brief Template

Copy this into your next brief and fill in the blanks:

Frequently Asked Questions About Voice Over Brief Tips

What should a voice over brief include?

A strong brief includes the final script, target audience, tone direction, pacing or length, reference spots, pronunciations, usage details and file specs. Even a short brief covering these basics will lead to a better first read.

How do I describe the tone I want for a voice over?

Use pairs and opposites, such as “confident, not cocky,” and describe a real moment the voice should feel like. Reference spots also help, as long as you note what you like about each one.

Should I include a temp track in my voice over brief?

Yes, if you have one. However, let your voice actor know whether it’s direction to follow closely or simply a placeholder for timing.

How many takes should I ask a voice actor for?

Most professional voice actors deliver a primary read plus a few alternates on key lines. Asking for two or three options on your most important line gives your editor flexibility without a second session.

Can I direct a voice over session remotely?

Yes. Many voice actors offer live directed sessions through Source-Connect, Zoom or phone patch. This lets you give real-time notes from anywhere, which is especially helpful for high-stakes or brand-sensitive projects.

Human vs. AI Voice Over: What Brands Should Know

September 22, 2026 by Leah Arscott

You’ve probably already had this conversation internally. Someone on the team ran a script through a synthetic voice tool. The result came back faster and cheaper than expected. Now there’s a real question on the table about which projects still need a human in a booth.

It’s a fair question. And the AI voice over vs human decision comes down to one thing: what the audio is actually doing for your brand. It has very little to do with arguments about authenticity.

I’ve narrated commercial and corporate work for over seven years. My clients include Google, Amazon, Apple, BMW, Porsche, Deloitte, Dell, and Salesforce. Over the past two years, I’ve also watched a lot of those clients navigate this exact decision. Some made the right call going synthetic. Others spent real money finding out they’d made the wrong one. Here’s the framework I’d use if I were sitting on your side of the table.

WHERE AI VOICE OVER GENUINELY MAKES SENSE

Let’s start here, because pretending otherwise would waste your time.

Synthetic voice has gotten good at a specific set of jobs. If your project falls into one of these categories, hiring a human may be an unnecessary expense.

Internal training modules and compliance content. Say it’s going to an internal audience. The script updates quarterly. Nobody outside your company will ever hear it. Synthetic voice is a reasonable choice here. Re-recording every policy change with human talent adds up fast, and your employees are not judging your brand by the narration.

Scratch tracks and animatics. Almost every agency I work with uses synthetic voice for timing passes now. It’s faster than booking talent for a rough cut. It also lets the creative team hear pacing before anyone commits to a direction. This is genuinely good workflow, and I’d recommend it.

High-volume content at scale. Think product description audio across thousands of SKUs. Automated notifications. Dynamic content that changes per user. No human can economically voice ten thousand variants, and no listener expects artistry from a shipping confirmation.

Accessibility and utility functions. Screen readers, navigation prompts, and similar functional audio. The job is clarity, not character.

Does your project live in one of those buckets? Then you have my blessing. I’d rather tell you that honestly than pitch you on something you don’t need.

Not sure which bucket you’re in? Send me your script and I’ll tell you straight.

WHERE AI VOICE OVER STARTS COSTING BRANDS MONEY

Here’s the part that gets expensive. And it’s rarely about the audio quality itself.

The problem shows up where the voice carries something other than information. Sometimes a voice needs to make someone feel a specific way. Sometimes it has to hold attention through a story. Sometimes it becomes a recognizable part of how your brand sounds. In those cases, synthetic voice tends to underperform. And the gap doesn’t show up until the work is already out in the world.

Interpretation is the piece that doesn’t transfer. A good read isn’t just correctly pronounced words at the right pace. It’s a performer making hundreds of small decisions. What matters in this sentence? Where do I lean in? What do I throw away? What is this line actually about underneath the words?

Synthetic voice can replicate the surface of that, and it increasingly does it well. But it can’t make those choices, because it doesn’t know what the line means.

That matters most where the audio is the product. Brand campaigns. Narrative advertising. Anything with humor, which is almost entirely about timing. Anything emotional, where being slightly wrong is worse than being flat. Character work, where a performance has to stay consistent across dozens of sessions.

AI VOICE OVER VS HUMAN: WHAT BRANDS SHOULD ASK FIRST

Rather than arguing the philosophy, here are the questions I’d actually run through.

Is the voice carrying the brand, or just carrying information? If someone could read this as text and lose nothing, synthetic is fine. If the delivery does work the words alone don’t do, you want a performer.

How long will this asset live? A two-week social campaign carries very different risk than a brand platform running for three years. The longer something lives, the more it matters that it holds up.

Will this voice need to stay consistent across future work? This is the one people miss. Build a brand around a synthetic voice, and you’re building on a specific vendor’s model. Those models get updated, deprecated, and repriced. Human talent can be re-booked in five years. A model version often can’t.

Who is the audience, and what will they notice? B2B buyers evaluating a six-figure purchase notice more than you’d expect. Consumer audiences on a fifteen-second social spot notice less.

What’s the cost of getting it slightly wrong? If a flat read costs you nothing, use whatever’s fastest. If a flat read costs you a campaign’s momentum, that math changes completely.

Weighing a specific project against those questions? Let’s talk about it. I’ll give you an honest read on whether you need me.

THE LICENSING QUESTIONS MOST BRANDS DON’T ASK EARLY ENOUGH

This is where I’d spend your attention. It creates actual legal and operational exposure, and it’s usually handled last.

With human talent, usage is well-understood territory. You license a defined scope for a defined term. Everyone knows what happens at renewal.

Synthetic voice is messier. Terms vary widely between providers. Here’s what to confirm before you build anything on a synthetic voice.

First, what was the voice trained on? Did the humans behind it consent, and were they compensated? This is becoming a genuine reputational question, not just an ethical one. Several jurisdictions are actively legislating in this space.

Second, what happens if the provider changes or retires the voice? If your brand identity depends on a specific synthetic voice, you want contractual clarity on availability. Current pricing isn’t enough.

Third, are your usage rights actually perpetual? Or are they perpetual until the terms of service change?

Fourth, do any regional restrictions apply? Some jurisdictions have significantly stricter biometric and voice-likeness laws than others. If you’re running campaigns across North America and Europe, those differences matter.

None of this makes synthetic voice a bad choice. It just means the diligence looks different from what your team is used to. And it’s better done before the campaign than during it.

WHY SOME BRANDS NOW CHOOSE HUMAN VOICE TALENT MORE DELIBERATELY

Something interesting has happened as synthetic voice became common. The presence of a real performance now reads as a signal in itself.

When a category fills up with competent, slightly generic audio, a specific human voice stands out simply by being specific. That’s not nostalgia. It’s contrast. For premium brands especially, sounding like a person rather than a product is becoming part of the positioning.

I’ve seen this most clearly with European clients. In my experience, they tend to raise provenance and talent consent questions earlier than North American clients do. But it’s showing up on both sides of the Atlantic now.

Working with me looks the same regardless of where your team sits. My studio runs a Neumann TLM 103 through a Focusrite Clarett, with Source-Connect for live remote direction. An agency in Toronto, London, or Milan can direct the session in real time and have broadcast-quality files the same day. Time zone hasn’t been a meaningful obstacle in years.

A PRACTICAL WAY TO SPLIT YOUR VOICE OVER BUDGET

The brands handling this well aren’t choosing one or the other. Instead, they sort their audio by what it’s doing.

Synthetic voice handles the volume work. Internal content, scratch tracks, functional audio, high-variant content. Anything where the job is clarity and speed.

Human talent handles the work that carries the brand. Campaign spots, brand platforms, narrative content. Anything with humor or emotional weight. Anything heard by the people whose opinion determines whether they buy.

Handled this way, the AI voice over vs human question stops being all-or-nothing. That split usually frees up more budget for the work that matters, not less.

FREQUENTLY ASKED QUESTIONS

Is AI voice over better than human voice over?

Neither is universally better. Synthetic voice suits internal training, scratch tracks, functional audio, and high-volume content where clarity is the goal. Human talent performs better where the read carries emotion, humor, brand identity, or narrative. Interpretation and timing are performance decisions, not technical ones.

When should a brand use AI voice over instead of hiring a voice actor?

Use synthetic voice when the audio is informational, internal, frequently updated, or needed at a volume no human could economically record. Hire a voice actor when the delivery does work the words alone can’t do. The same applies when the asset will live a long time, or when the voice needs to stay recognizable across future campaigns.

What are the licensing risks of using AI voice over?

The main risks are unclear training data provenance and uncertain long-term availability of a specific voice. Usage rights can also change with a provider’s terms of service. On top of that, biometric and voice-likeness law varies by region. These are worth resolving before a campaign is built, not during it.

Can AI voice over replace a brand’s signature voice?

Technically it can produce consistent output. However, it introduces vendor dependency. If a provider updates, reprices, or retires a model, a brand identity built on that voice becomes difficult to maintain. Human talent can be re-booked years later, which makes it the more durable choice for long-running brand work.

Do European and North American brands approach AI voice over vs human talent differently?

In my experience, European clients and agencies raise questions about training data, talent consent, and provenance earlier in the conversation. That partly reflects a stricter regulatory environment. North American clients increasingly ask the same questions, just often later in the process.
