What a Voiceover Demo Should Sound Like
Short answer: a voiceover demo is a short sequence of separate pieces, each one written and produced so it sounds like real work that is already airing. The performance matters, but so does the writing and the mix, because a buyer is listening for whether you sound like something they could actually cast.
The part people most often miss is that you generally need a separate demo per category. Commercial, animation, promo, radio imaging, and audiobook narration are different products for different buyers. One demo that tries to cover all of them tends to satisfy none of them.
Video games are the usual exception. In Shamy's experience most people do not carry a separate games demo, because that work tends to get cast off the animation demo.
Why one demo cannot cover everything
Voiceover is bought by category, and it is usually bought by different people. A commercial agent is filling commercial breakdowns. An animation casting director is filling character roles. A promo producer wants to know you can carry urgency and a network's tone inside eight seconds. They are not the same listener, and they are rarely in the same room.
So when a single demo tries to cover all of it, most of what any given listener hears is material aimed at somebody else's job. The demo is not bad, it is just diluted, and diluted is a hard thing to cast from.
The categories, and which ones want their own demo
- Commercial. Brand reads, retail, automotive, pharma, the conversational stuff that dominates the category right now.
- Animation. Character work. Range matters here more than anywhere else, but it has to be range in service of castable characters rather than a tour of accents.
- Promo. Network and streaming promotion. Its own rhythm and its own energy, and a commercial read rarely covers it.
- Radio imaging. Related to promo but genuinely separate: station branding, sweepers, liners, and the way a voice sits on top of a music bed.
- Audiobooks and long form narration. A different skill entirely. What a producer wants to hear is sustained, comfortable reading and character consistency over time, not a montage.
- Dubbing. Anime and foreign language dubbing, where the job includes hitting picture and matching an existing performance.
- Video games. Often folded into animation, as above. Where a separate games demo earns its keep is when you are chasing work animation does not show, like combat efforts, tactical and military realism, or sustained creature work.
None of this is uniform across agencies or markets. Some agencies want exactly the categories they rep and nothing else; some are happy to hear two. The safe move is to look at how the agency organizes its own roster and follow that.
What each spot has to sound like
The single most useful standard is this: each piece should sound like it was lifted out of something real. A real campaign, a real show, a real station. It was not, and everyone listening knows it was not, but it should be written, performed, produced, and mixed to that standard anyway.
In practice that means copy that sounds like copy someone actually wrote for a brand rather than a demo script, music and sound design appropriate to the format, and a mix where your voice sits the way it would sit in the finished piece. A great read dropped into a thin mix still reads as a demo, and a demo that sounds like a demo is competing against material that does not.
It also means each piece should be short and clearly different from the one before it. Contrast is what makes a demo feel like range. Length is what makes it feel like a chore.
Order and length
The first piece does most of the work, because that is where the decision often gets made. It should be the most castable thing you have, which is not always the most impressive thing you can do. Those two are different, and the gap between them is where a lot of demos go wrong.
Commercial demos commonly run about sixty to ninety seconds, animation around a minute. Narration samples work on a different logic. Whatever the category, it is usually worth asking of every single piece whether it is there for the buyer or there for you.
Producing it, and what that costs
A produced demo means somebody writes copy tailored to your voice, directs the sessions so you are not judging your own takes, and mixes the result so each piece lands like a finished spot. That is the part that is genuinely hard to do alone, and it is usually the writing and the mix that give away a self-produced demo rather than the acting.
Cost varies widely by producer and market, and it is normal for a fully produced demo to run from the high hundreds into the low thousands of dollars. Before paying anyone, listen to several demos that producer has actually made, and ask yourself whether they sound like the work you are trying to book. A producer who is excellent at animation is not automatically the right person for promo.
The mistakes that come up most
- Range for its own sake. A demo built to prove versatility often ends up proving nothing castable. Casting people are trying to place you, not admire you.
- Impressions. Almost never help on a demo, and they frequently take the place of something that would have.
- Copy that does not sound like copy. Writing to showcase a voice reads differently from writing that was selling something, and the difference is audible fast.
- Overprocessing. Heavy compression and effects can flatten exactly the thing somebody is trying to hear.
- Length. Almost nobody has regretted a demo being too short.
- Age. An old demo is not just dated in style, it also usually represents a version of you that has been outgrown.
When to recut
The two usual triggers are that the demo no longer sounds like what is currently airing, or that your real work has moved past it. Neither is an emergency. But a demo is the thing standing in for you in rooms you are not in, and it is worth checking every so often whether it is still doing that job or just holding the spot.
Common questions
How many voiceover demos do you need?
One per category you are actually pitching, rather than one that tries to cover everything. Most people start with a single demo in their strongest category and add others as they build work in them. Two strong demos are worth more than five thin ones.
Do you need a separate video game demo?
Often not. In Shamy's experience video game work tends to ride along with the animation demo rather than getting its own, because the casting overlaps heavily. A separate games demo makes more sense once you are specifically chasing work that animation does not show, such as combat efforts, military or tactical realism, or sustained creature and monster work.
How long should a voiceover demo be?
Commercial demos commonly land around sixty to ninety seconds and animation demos around a minute, built from short distinct pieces. Narration and audiobook samples work differently, since the point there is sustained reading rather than a montage. These are conventions rather than rules, and the more useful instinct is to cut anything that is not earning its place.
Should you produce your own voiceover demo?
You can, and some people do it well, but it is harder than it looks. A produced demo is written for your voice, directed by someone who is not you, and mixed so that each piece sounds like a finished spot. Self-produced demos most often give themselves away in the writing and the mix rather than the performance.
How much does a voiceover demo cost?
It varies a lot by producer and market, and it is normal for a fully produced demo to run from the high hundreds into the low thousands of dollars. Before paying anyone, listen to several demos that producer has actually made and ask whether they sound like the work you are trying to book.
How often should you recut a voiceover demo?
When it stops sounding like what is currently airing, or when your actual work has moved past it. Styles shift, and a demo cut to a read that was current several years ago can date faster than the performance underneath it deserves.
