Somewhere in most UK casting briefs there is a line that reads: clear, neutral English.
Nobody who writes it means any harm by it, and almost nobody who writes it could say what a neutral accent would sound like. What the line does in practice is narrow the country to a handful of ways of speaking, and then wonder why the videos feel like adverts.
The question underneath
The brief is trying to ask which voice sounds trustworthy. That question has an answer in Britain, and the answer is not a media fact.
Trust is doing a job it should not be doing
Whatever your ear tells you sounds credible was installed by decades of broadcasting, and it tracks class more closely than it tracks anything to do with your product.
You do not have to have a position on that to notice the commercial problem with it. If you cast the voice that sounds like it is telling you something official, you have cast the voice of an advert, and you paid for UGC specifically to not sound like one.
What you actually want is proximity
The useful test is not whether the person sounds authoritative. It is whether they sound like somebody in the viewer's own life who might plausibly mention this product.
That person is not neutral. They are from somewhere, they use the words people use where they live, and when they say the product is worth it, nothing about the delivery is asking to be believed. It just is or is not.
The instinct fires at review, not at casting
You can write a good brief and still lose this, because the moment of failure is later.
The takes come back, somebody in the room says can we get one that is a bit more polished, and nobody in the meeting can define polished. The brief was never the problem. The review was.
The fix is to decide before you watch anything what would count as a fail: inaudible, off script, product not visible, claim you cannot run. Then a preference has to be argued as one of those or dropped. Not liking a voice is allowed. Not liking a voice while calling it a quality issue is how the neutral line gets back in through the side door.
| What the brief says | How a creator reads it | What it does to the take |
|---|---|---|
| Clear, neutral English | Do not sound like where you are from | Flattened delivery that sounds read |
| Professional tone | Perform being a presenter | Formality the viewer scrolls past |
| Speak slowly and clearly | Enunciate | The pace of an instruction video |
| Talk like you would to a friend | Be yourself | Usable takes, first time |
| Say the brand name three times | Hit the marks | Everything in between goes dead |
Look at the fourth row. It is the only line in the left column that describes a situation rather than a sound, and it is the only one that produces something you can use.
Cast for the segment, not for the country
Britain is not one audience, and you are not obliged to pick one voice for it.
If your buyers in Glasgow and your buyers in Bristol are genuinely different people, cast both and run both. The reason this is worth saying is that it is nearly free here: three voices means three creators, not three shoots, three crews and three days. In almost any other format that decision would be a budget conversation. In UGC it is a shortlist.
The same logic applies inside a city. A product bought by students and a product bought by their parents can share a brief and should not share a voice.
Write the brief differently
Stop describing the sound. Describe the situation, and let the sound be whatever it is.
Say who the person is talking to, where they are when they say it, and what they are holding. Say what they should not do: no presenting, no reading, no brand name at the top. Then let them talk.
If you must have a constraint on delivery, make it one anybody can act on without editing themselves out of the take. Audible over background noise is a real instruction. Neutral is not.

Frequently asked questions
Should I ask for a specific regional accent?
Only if your audience is regional. Casting a region because it sounds authentic to a marketing team is the same mistake in reverse, and creators can hear it in the brief.
Does a strong accent hurt reach?
The thing that hurts reach is delivery that sounds performed. A creator speaking normally in their own voice will hold attention longer than the same person carefully not sounding like themselves.
What about subtitles?
Burn them in as a matter of course, for every voice. It is an accessibility default and a sound-off default, and it quietly removes most of the anxiety that produces the neutral line in the first place.
How many voices should I test?
Start with two that are genuinely different, not two versions of the same casting instinct. If both perform the same, you have learned something cheap. If they do not, you have learned something worth a lot more.
