Matt Lucas and Hugh Bonneville among actors calling for law on AI voice cloning

Actors including Matt Lucas, Hugh Bonneville and Nicola Coughlan have written to the UK government demanding greater protection against their voices being used by AI.

The performers are asking Prime Minister Andy Burnham to introduce legislation which would give every person in the UK a legal right to own their voice.

Voice clones are created by training AI on recordings of real people. Quick versions can be made in minutes from a few seconds of audio, but high-quality copycats tend to require hours.

Audiobook narrator Alice Sockett, who co-founded the campaign, called it "an existential threat to our entire industry".

"My voice is out there in the public domain but completely unprotected," she said.

"We're seeing voice theft increase every week."

A government spokesperson told the BBC that, while "digital replicas can be a powerful tool, including for the creative industries," there was also possibility for harm.

"We value and protect human creators, and that is why we have announced we will launch a consultation on how we address these harms, while protecting legitimate innovation", the spokesperson said.

More than 80 performers have signed the letter, with Derry Girls actor Siobhán McSweeney saying she was "deeply worried" that the government was lagging behind.

"There is a way to work alongside AI and to use it as a tool that benefits us rather than rendering us obsolete," she said.

"Our audiences want that human connection. Not AI."

As well as actors, other signatories include those working in other performing industries.

That includes Scottish singer Sandi Thom, known for her 2006 hit I Wish I Was a Punk Rocker (With Flowers in My Hair).

She said she was signing the letter because her voice was "unique to me and was handed to me at birth".

"Behind that voice is the emotion, the life, the pain, the tears and joy that I've felt along the way," she said.

It comes a few months after lawyers warned UK legislation has become "unfit for purpose" because of the advancements of AI tech.

"The law comes close, but it doesn't fully protect your voice, your face or your identity," Dr Mathilde Pavis said in June .
