STORY: His catchphrase may be "you can't see me", but you may soon hear John Cena as a chatbot.

"So, like, I officially am not cool. So that's that's exactly what I found out"

This is what Facebook-owner Meta's AI bot might sound like as it plans to announce it has secured a deal with the WWE and movie star, a source told Reuters.

Cena, as well as other celebrities like Judi Dench and Kristen Bell, will reportedly give voice to the bot.

'Who wants to slow down? No, I want to be employed.'

The source said the new audio feature will offer users the option to select a voice for Meta's ChatGPT-like digital assistant from a list of five celebrities.

Others include actors Awkwafina and Keegan-Michael Key, as well as several generic voices.

They added the social media giant is set to announce the audio capabilities at its annual Connect conference, which starts on Wednesday. (September 25)

The celebrity voices will start launching in the U.S. and other English-speaking markets this week, the source said.

And they will feature across Meta's family of apps, which include Facebook, Instagram and WhatsApp.

Meta has raced to push out generative AI products to its billions of users.

It is competing against Microsoft-backed ChatGPT-maker OpenAI and Alphabet's Google to dominate the emerging technology.

The company has added capabilities to its chatbot and pushed to make it a more prominent part of the experience of using its apps.

OpenAI showed off a similar audio feature for its chatbot in May.

But it quickly ran into trouble when actor Scarlett Johansson accused the company of making it sound "eerily similar" to her, even though she had declined to lend her voice to the project.
