The Christmas Ad Voiceover Wasn't Human

UK postal service Royal Mail has admitted that the voiceover in its Christmas ad campaign was generated by artificial intelligence. The controversy began with a viewer's objection: Lucy Wynne, daughter of BBC voice-over artist Paul Vaughan, who passed away in 2014, was convinced that what she heard was her father's voice.

It all started in November 2025, when the campaign aired on ITV. The moment Wynne heard the final line of the ad, she recognized the voice. Those around her initially thought she was overreacting — after all, Vaughan had never recorded a single spot for Royal Mail during his lifetime.

Suspecting that someone's voice had been used without permission, Wynne took the matter to Deadline, the US-based entertainment news outlet. Under questioning, Royal Mail confirmed that the voiceover did not belong to a real person and argued that this kind of use had become commonplace. However, not a single word had been spoken by a human being to create the voice used in the ad.

The Voice Came from the Czech Republic — and the Owner Is the Same Person

The campaign concept came from the agency Darwin & the Machines. The short narrative segments in the ad were filmed in the UK by Untold Studios using real actors. The only outsourced element was the continuous narration (voiceover), which was handled by Czech AI company Fameplay.

The critical detail that was overlooked was the connection between the companies involved. Czech businessman Daniel Křetínsky heads Czech Media Invest, one of Fameplay's investors. Royal Mail is also owned by Křetínsky's company, EP Group. A source who worked on the project told Deadline that Juraj Felix of Fameplay was present at recording sessions and was very enthusiastic about AI-powered voiceover. According to the same source, the production team had prepared a warning that this approach might not be appropriate for a British brand. The technology in question was licensed from ElevenLabs for Fameplay, and the company states that Vaughan's name or recordings were never used in the prompts. ElevenLabs has confirmed that the voice is not an exact replica of Vaughan's. When asked whether the model was trained on his recordings, however, they gave no clear answer.

Who Was Paul Vaughan?

• Narrator of the BBC science programme Horizon (1968–1995) • Presenter of Radio 4's arts programme Kaleidoscope (1973–1998) • Narrator of the 1984 nuclear war film Threads • The voice behind Orange's first UK ads, as well as Tesco and Colgate campaigns • Narrator of the Paddington audiobooks

A career spanning half a century means that a large number of clean, professional recordings of Vaughan exist — exactly the kind of material used to train AI voice models.

The Company Claims "No Resemblance" — But the Evidence Says Otherwise

According to Royal Mail, the voice was not designed to imitate any specific person; producers carried out checks and found no issues regarding resemblance. However, independent assessments paint a different picture:

• Dr. Nadine Lavan (Queen Mary University, voice psychology): Research shows that people are remarkably skilled at recognizing the voices of those they are close to. The fact that the voice generator appears to have been designed to mimic Vaughan and produced a result startlingly close to his voice is a strong indicator.
• Prof. Vincent Hughes (University of York, forensic speech science): Compared a single sentence from the ad with genuine recordings of Vaughan. Although the sample was short, a notable overlap was identified in the pronunciation of vowels and consonants and in the overall timbre of the voice.
• Three open-source analysis tools: All three tools tested by Deadline indicated a high probability that the two voices belonged to the same person.

The Family's Reaction: Nobody Asked

What upset Wynne most was not the voice itself, but the fact that nobody had taken the trouble to verify the situation in full. In her view, releasing a voice so reminiscent of her father's without knowing whether he was alive or ill is unacceptable. She believes her father would have hated the way machines imitate the expressive richness of voice-over artists' voices. Her advice to Royal Mail is simple: hire an artist and pay them properly.

Wynne was only contacted once. Royal Mail, for its part, merely referred to its procedures for addressing serious concerns. ElevenLabs also noted that Vaughan's name appears on their list of individuals whose voices are prohibited from being cloned on their platform.

Peter Caulfield, founder of the "Save Our Voices Now" campaign launched to protect voice-over artists, also weighed in on the incident. According to Caulfield, it is not surprising that a voice resembling Vaughan's would be sought for an ad of this kind, or that a machine operating at this level would produce a result this close to his voice. Even so, it is those who have lost someone they love who are paying the price.

So What Does This Mean for Voice-Over Artists in Turkey?

This case points to a far more complex territory than the usual "voice cloning" debate. Even if no one admits to using your recordings, an AI model can produce a voice strikingly similar to yours — and proving that is far harder than proving direct copying.

In Turkey, too, advertising voiceover work frequently passes between agencies and production companies, and listeners are rarely informed about who they are actually hearing. With that in mind, here are some steps voice-over artists can take right now:

1. Clearly state in contracts that recordings may not be used for AI training purposes.
2. From the very start, when accepting a job, ask the client whether synthetic voice technology will be used anywhere in the project.
3. Log any broadcasts featuring a voice similar to their own, note the dates, and consult a legal expert.
4. Particularly for the families of deceased voice-over artists, evaluate the issues of voice rights and personality rights with a lawyer.
