You’ve heard it. The read that’s technically fine — clear diction, good energy, hit every word on the script — but the second it plays for a room of 19-year-olds, someone winces. It sounds like an adult doing an impression of a young person. And no amount of “make it more fun!” direction fixes that in the booth, because the problem was never energy. It was authenticity.
If you’re casting for a brand trying to reach Gen Z, you already know the stakes are different than they were five years ago. This isn’t an audience that responds to being sold to in the traditional sense — they respond to being talked to like a peer would talk to them. Get the voice wrong and it doesn’t just underperform, it can actively read as out of touch, which is worse than neutral for a brand trying to build credibility with this demo.
I’ve voiced spots for brands like TikTok, Xbox, and Barbie — three very different tones, but all of them required the same underlying skill: knowing exactly where the line is between “sounds like a real person” and “sounds like marketing.” Here’s what I’ve learned actually separates a Gen Z commercial voice that works from one that doesn’t.
The Difference Between Conversational and Performative
Gen Z has grown up saturated with ads, which means their radar for performance is finely tuned. A voice that’s “acting casual” registers differently than a voice that actually is casual. The tell is usually in the rhythm — performative reads tend to hit every beat evenly, like the actor is checking boxes (energy, check, enthusiasm, check, call to action, check). A voice that actually works has natural variation. It speeds up when the idea is exciting and it doesn’t over-explain. It trusts the listener to keep up.
This is the single biggest note I give myself in the booth for this kind of read: don’t perform excitement, locate it. If I don’t actually find the moment in the script interesting, no amount of vocal energy fixes that — and Gen Z listeners can hear the difference between real and performed enthusiasm faster than almost any other demo.
[Demo: this is a great spot to drop in a Gen Z / youth-skewing commercial reel — something with a social-first or app/gaming brand shows the tone best]
If you’re scripting or casting for this kind of spot and want a read that actually lands instead of one that just checks the “young and energetic” box, send me your script — I’ll tell you honestly if the tone is going to work before we’re in the booth.
Why Slang Isn’t the Shortcut You Think It Is
A lot of briefs I get for Gen Z-targeted work lean hard on slang in the copy, assuming that’s what signals “we get this audience.” It’s usually the opposite. Slang has a shelf life measured in months, and nothing dates a spot faster — or reads more try-hard — than a brand using language that was already retired by the time the ad aired. Worse, if the delivery doesn’t sound completely natural saying it, the slang just highlights the disconnect instead of covering for it.
What actually reads as authentic isn’t the vocabulary, it’s the attitude underneath the vocabulary — dry, a little self-aware, not overly earnest, comfortable being direct instead of hyping something up. You can write a script with zero slang in it and still nail a Gen Z tone if the delivery has that quality. I’d rather work with a client on cutting slang that’s going to feel dated in six months than deliver a read that sounds current for one news cycle and cringe for the next two years of the campaign’s life.

Pacing: Why Slower Often Reads Younger
This one surprises a lot of creative directors. The instinct is often “young audience, keep it fast, keep the energy up.” But rushed pacing frequently reads as anxious or oversold — which is the opposite of the confident, unbothered tone that actually connects with Gen Z listeners. The reads that land tend to have more space in them. Pauses that let a line breathe. A willingness to let something be understated instead of punched.
Think about how actual conversation between people in their late teens and twenties moves — it’s not manic. It’s often quite deadpan, with the humor landing because of the delivery, not despite it. A commercial voice that mimics that rhythm, rather than defaulting to the traditional “commercial announcer” cadence sped up, is going to feel far more native to the audience than a fast, hyped-up read ever will.
Where Broadcast Polish Actually Hurts You
This is the note that’s hardest for some clients to hear, because it goes against decades of commercial VO instinct: sometimes the “cleaner,” more polished, more traditionally professional read is the wrong choice for this audience. Broadcast polish — the crisp diction, the rounded-out phrasing, the classic “commercial voice” quality — can read as corporate and distant to a Gen Z ear, even when it’s technically excellent.
That doesn’t mean the read should be sloppy or unclear — it still needs to serve the brand and the message. But there’s a version of polish that works here, and it’s less about vocal perfection and more about precision in choices: exactly the right amount of edge, exactly the right restraint, delivered by someone who understands why every choice is being made rather than someone defaulting to “commercial voice” mode because that’s the safe, trained instinct.
This is really a casting decision as much as a performance one. It’s worth asking any voice actor you’re considering for this kind of work how they’d approach dialing back that trained broadcast instinct — because for a lot of voice talent, that instinct is deeply ingrained, and undoing it on the fly in a session isn’t something everyone can do convincingly.
Let’s talk about your project if you’re casting for a youth-skewing campaign and want to talk through tone before you write the brief — sometimes the direction that gets you the best read is different than what the traditional commercial playbook would suggest.
What This Looks Like Across Markets
I work with both North American and European brands and agencies on this kind of casting, and one thing worth flagging: “Gen Z voice” isn’t a single monolithic tone globally. What reads as authentic and current to a North American Gen Z audience has real differences from what lands with European audiences in the same age range — different comedic sensibilities, different relationships to directness, different cultural reference points for what “trying too hard” even looks like.
My studio is fully set up for remote sessions regardless of where your team is based — Source-Connect, broadcast-quality home recording, and I work across time zones comfortably, so distance isn’t a barrier to getting the right take dialed in together, whether you’re in Toronto, London, or anywhere in between.
Frequently Asked Questions
What makes a voice sound authentic to a Gen Z audience?
Natural rhythm and understated confidence tend to matter more than vocabulary or energy level. A voice that sounds like it’s talking with the listener, rather than performing at them, reads as more authentic regardless of the specific words in the script.
Should a Gen Z commercial script use slang?
Not necessarily. Slang dates quickly and can feel forced if the delivery doesn’t sound completely natural. A dry, direct, self-aware attitude in the read often lands better than slang-heavy copy delivered with a performed tone.
Does a Gen Z voice over need to sound young?
Not literally — it needs to sound current in attitude and delivery, not necessarily in age. Plenty of effective Gen Z-targeted commercial reads come from voice actors outside that exact age bracket who understand the tonal cues that read as authentic.
Why does traditional commercial polish sometimes hurt a Gen Z-targeted ad?
Classic broadcast diction and cadence can read as corporate or distant to younger listeners, even when it’s technically well performed. A more restrained, conversational delivery style often connects better with this audience than the traditional “announcer” read.
Is pacing different for Gen Z commercial reads compared to traditional commercials?
Often, yes — slower, more natural pacing with real pauses tends to read as more confident and authentic than a fast, high-energy delivery, which can come across as oversold to this audience.
