Voice over: integrity and traceability of audio files

An unavoidable question in the age of AI

Twenty years behind the microphone as an independent female voice over artist, and one foundation has never changed: trust. Trust in the human relationship, in what has been agreed with the client, in how each delivered recording will be used. For a long time, that model was enough.

A delivered file can be adapted, passed on and reused. The question is very practical: what happens to a production carrying my voice once it leaves the studio?

Why this question matters today

A TV campaign, a corporate film, a radio commercial: the project begins with a defined use. Then come versions, new media and sharing. Each time the file changes hands, some of its context can be lost.

Voice cloning adds another possible form of reuse. This observation does not call my clients into question: it invites us to maintain the link between a recording, its origin and what was agreed.

When a production raises questions later on

Some time ago, I came across a TikTok video. A cable car in the Île-de-France region, passengers filming, and in the middle of it, an audible warning. My voice. I recognised the tone in the first second, without a moment’s hesitation.

Yet I could not remember when I had recorded that message, for which client or under what contractual terms. I was not disputing anything or criticising my partners. It was simply a fact: I could no longer see what had happened to that production.

There is nothing unusual about this situation. Once delivered, an audio production travels far beyond what we can individually keep track of.

A few months later, the story went much further than that uncertainty. In spring 2026, I found my voice cloned without my consent on Fish Audio, an AI platform, on two unauthorised accounts, one named after me. Available for anyone to use, ready to say anything to anyone. And it was not just mine: my daughter Florine’s voice was there too, cloned under a pseudonym, with almost 14,000 uses. The full story and exact procedure for getting a clone removed are in My voice was stolen: here is how I had it removed.

In my case, I had to provide the evidence needed for the complaint after discovering the clones. This account does not describe every platform’s current checks. It raises a simple question: how can a performer’s consent be verified before reuse?

An issue for the whole profession

Voice actors, studios, agencies, producers and advertisers are involved at different points in a file’s life. Preserving its useful context therefore cannot depend on one person alone.

I want to be able to trace a use and discuss it with my partners. It is a matter of clarity in our work, not suspicion in the relationship.

Integrity and traceability

The word “inviolability” expresses an ambition. In practice, we need to distinguish a file’s integrity, checking whether it matches a reference version, from traceability, which documents its journey. Neither makes a recording impossible to copy.

The terms of the work remain distinct from the technology: Article L. 212-3 of the French Intellectual Property Code establishes the principle of a performer’s written authorisation for the uses it lists. The CNIL explains the risks of misuse of someone’s image or voice and how to report it.

What is still missing

Understandable information, simple tools and a shared framework: that is what would make this traceability useful day to day. Technology alone does not resolve questions of distribution and rights.

Documenting a use should help us understand and talk to one another. I hold firmly to this limit: protecting creative work without introducing blanket surveillance.

A discussion already under way in the profession

Protecting voices and addressing AI are already the subject of collective work. “Touche pas à ma VF” has brought these issues into public debate; the National Association of Voice Actors also addresses them internationally.

These discussions bring together questions of creativity, technology and law. The tools deserve to be examined for what they can actually establish, including their limitations.

Opening a conversation: the spirit of Apéro Voice

With that in mind, I devoted an Apéro Voice gathering to these questions on 28 January 2026, with Loïc Thaler, a fellow Flemish voice actor who had been involved for two years in developing an application dedicated to voice traceability. The aim was not to sell a ready-made solution: it was to inform, raise awareness, bring people together, take stock and think collectively about a clearer future for our profession.

Why talk about it now?

The speed at which uses develop pushes us to look for an immediate answer. I prefer to take the time to distinguish what exists, what works in a specific case and what remains a possibility. That is also a way of preserving trust.

What next?

At the start of a project, a clear framework already helps a great deal: which recording, for which media, in which territory, for how long and with what reuse planned? This information makes a conversation possible when the project evolves.

My voice becomes part of your production. The link between that production and its use deserves to remain clear, for you and for me.
