You don't need to speak Spanish to brief a Spanish voice over session well. What you need is clarity about what you actually want — and the discipline to communicate it in terms that translate across languages. I've worked with hundreds of English-speaking clients at brands like Ford, Netflix, and Google who don't speak a word of Spanish, and the sessions that go smoothly share the same characteristics. The ones that derail share different ones.
Here's what makes the difference.
Stop Describing Accents You Can't Hear
The biggest mistake non-Spanish speakers make is trying to specify regional accents they can't actually distinguish. "I want a Colombian accent because it sounds friendly" or "I want Castilian because it sounds sophisticated" — these requests almost always come from someone who learned that accents exist but has no idea what they actually sound like.
According to Ethnologue, there are over 20 distinct Spanish dialect regions across Latin America and Spain. You're not going to learn to distinguish them from a blog post.
And here's what American clients often don't realize: the Castilian accent doesn't sound sophisticated to Latin Americans. It sounds like someone from Spain. Latin Americans mock Spanish people — it's closer to the opposite of the British accent effect Americans imagine. A Nielsen study on US Hispanic media consumption found that 73% of bilingual Latinos prefer Latin American Spanish in advertising. They're not being difficult. They're responding to what sounds natural to them.
The solution? Request neutral Spanish. It works across all Spanish-speaking markets without triggering regional associations or rivalries. That's what I recommend for every pan-Hispanic campaign, and that's what Fortune 500 brands use when they want to reach the entire market.
What Actually Belongs in Your Brief
A good brief for a Spanish voice over session includes these elements:
The final script in Spanish. Not the English original with a note saying "translator will handle." The actual Spanish script, already translated and edited for length. Spanish runs about 30% longer than English — if your translator gave you a word-for-word conversion, it won't fit the timing. Have someone who knows what they're doing cut it down before the session, or you'll spend the first hour watching me try to cram 40 seconds of Spanish into a 30-second slot.
Reference audio or video. Show me the tone you want. A previous spot you liked, a competitor's ad, even a movie scene. I don't need you to describe "warm but authoritative with a hint of playfulness" — I need to hear what that means to you. (I've received briefs with contradictory adjectives so many times I've lost count — "professional but casual, serious but fun, energetic but calm.")
The music track. If you have it, send it. Recording against the actual music helps me match the energy and pacing. It's the difference between performing in context and guessing what context you'll create later.
Technical specs. Sample rate, file format, where you need the files delivered. Source Connect session or file delivery? These details save 15 minutes of back-and-forth.
What you're selling and to whom. I'm not asking for your entire marketing strategy. But "this is a pre-roll ad for a banking app targeting first-generation Mexican-Americans aged 25-40" tells me more than "make it sound authentic."
The Direction That Doesn't Help
Have you ever tried to explain what you want using only adjectives? Clients do this constantly. "Make it more... real. More human. Less announcer-y."
I've been hearing "don't sound like a voice over" for at least a decade now. What clients mean when they say this is "don't sound like a 1950s radio announcer." They still want a professional who speaks clearly, delivers on tempo, and interprets the script with intention. They just don't want it to sound like someone selling used cars.
The problem is that direction like "be more natural" gives me nothing actionable. Natural compared to what? My first take was natural — my fifteenth take after confusing direction is where things start sounding weird.
Better direction sounds like this: "Faster in the first half, let the last line breathe." Or "This is a dad talking to his daughter, not a spokesman talking to a camera." Or "Listen to this reference — match that energy in the middle section."
Trusting What You Can't Verify
Here's the uncomfortable truth: if you don't speak Spanish, you cannot evaluate whether my pronunciation is perfect, whether my phrasing sounds native, or whether I'm hitting the emotional beats correctly.
You have to trust someone who can.
The US Census Bureau reports that over 41 million people in the United States speak Spanish at home. If you're producing Spanish content, someone on your team — or your client's team — speaks it. Get them in the session. Not to direct, necessarily, but to confirm that what I'm delivering actually sounds right to a native ear.
What you can evaluate: pacing, energy, whether the read matches your visual edit, whether I'm taking direction and adjusting. What you cannot evaluate: linguistic authenticity. A non-native cannot reliably tell the difference between a native speaker and a fluent one. The subtleties are too complex. Viggo Mortensen, Anya Taylor-Joy, and Alexis Bledel speak better Spanish than Danny Trejo, Jennifer Lopez, and Selena Gomez — because the first group grew up speaking it in Argentina. The second group have Latino names and barely speak a word.
If your brief says "native Spanish speaker" and you can't verify that yourself, you're relying on the talent to be honest. Work with someone you trust.
Why the First Take Usually Wins
Clients who don't speak the language often compensate by asking for more takes. Twenty, thirty, fifty variations. The logic seems sound: if I can't tell which one is best, I'll collect enough options that someone else can sort it out.
But here's what happens in practice. Take one is my best interpretation of your script and brief. Take two is a slight adjustment. By take fifteen, I'm second-guessing everything, and the performance sounds overthought. By take thirty, we're both tired.
Then you send all thirty takes to your Spanish-speaking colleague, and they pick take one.
The first take captures the most natural interpretation. Every take after that is a reaction to direction — useful if the direction is clear, counterproductive if we're just generating volume. If you want a session that runs efficiently, learn how to direct with specificity, get a native speaker in the room, and trust the professional to deliver.
Skip the Casting Platforms
If you're tempted to post your Spanish voice over project on Voices.com or Voice123, don't. You'll receive thousands of proposals, most from people who are not professional native Spanish speakers, and you'll have no way to evaluate who's actually qualified. The algorithm matches what talents claim they can do with what you claim you want — and according to a 2023 industry survey by Gravy for the Brain, only 12% of voice actors on major platforms earn a full-time living from the work. The rest are hobbyists, beginners, or people gaming the system.
What works better: contact a professional directly and ask for 2-3 variants. You'll get usable options from someone vetted, delivered fast, without wading through a pile of demos you can't assess. That's why clients at companies like Amazon and Coca-Cola call me directly — they've learned that having too many options doesn't help.
Send the Brief Before the Session
Everything I've described should arrive before we get on the call. Not during. Not "I'll explain it when we start."
When I receive a proper brief 24 hours ahead, I can review the script, flag potential timing issues, prepare the read, and show up ready to perform. When I receive the brief during the session, you're paying for me to read while you wait.
And if the script needs editing because Spanish runs long? That's a conversation to have before the session starts — not a problem to discover when we're already on Source Connect and your entire production team is watching the clock.
The brief is the work before the work. Do it well, and everything else runs smoother than you expect.
