In 2018, cognitive scientists Eryn Newman and Norbert Schwarz played people recordings of experts presenting their work, then degraded the sound quality on half of the clips. The words and the speakers were identical. When the audio was harder to listen to, people judged the speaker as less intelligent and less credible, and rated the content itself as less important. A 2025 study from Yale, published in the Proceedings of the National Academy of Sciences, found the same effect held even for synthetic voices.
Most businesses will never present research at a conference, but the finding lands close to home. Every explainer video, product demo, radio advert and on-hold message is a moment where a customer forms a judgement about your company, partly on how it sounds. Poor audio does not simply sound cheap. It makes the business behind it seem less trustworthy, before a word of the actual pitch has landed.
Voice shows up in more places than owners expect
It is easy to think of voice over as something only advertisers or broadcasters buy. In practice it runs through the everyday touchpoints of an ordinary business: the video on your homepage, the demo that supports a sales call, the training modules new staff sit through, the recorded menu customers hear when they phone in. Each of those is a small, repeated impression of how professional the company is. When they sound polished, the business sounds established. When they sound thin or mismatched, a growing company can end up sounding smaller than it is.
The false economy
The quickest, cheapest route usually looks like a saving on the invoice: a colleague with a decent microphone, a low-cost freelancer from a marketplace, or an AI voice for the price of a subscription. The cost tends to appear somewhere else. A demo that undercuts a premium price. An advert that has to be re-recorded because the read was wrong for the brand. A phone system that quietly tells every caller the operation is smaller than the website suggests. None of that shows up in the original quote, which is exactly why it is easy to miss.
The risk almost nobody prices in
There is also a commercial risk that rarely reaches the budget: usage rights. A voice recorded and licensed for your website is not automatically cleared to run in a paid television or radio campaign, and reusing it without sorting the licence can mean renegotiation or exposure later. For a business, that is a legal and financial question, not a creative one. It is also the kind of detail that a voice over agency handles as a matter of course: casting, recording to broadcast standard, rights and revisions sit with one accountable team, so a problem is theirs to fix rather than a cost that lands back on you.
How to make the call
Treat it like any other supplier decision. For a one-off, low-stakes recording, a single freelancer may be perfectly fine. Once voice becomes recurring or public-facing, the real question is who is responsible when something goes wrong. Ask to hear work similar to yours rather than a general showreel. Confirm who manages the project and what happens if a recording needs redoing. Get the intended usage in writing. And match the choice to the ambition: the right partner for a single video is not necessarily the right one for a brand that will be producing content for years.
The voice is one of the cheapest components of most productions and one of the most visible. Spending a little more to get it right once is usually cheaper than paying to fix it twice, and it protects something harder to put a number on: how much a customer trusts the business before they have spoken to a single person in it.
