Artificial intelligence and voice replication continue to come under fire lately, as prominent voice actors are making a stand against the unauthorized use of their vocal talents. The most recent to voice his concern (get it?) is Paul Eiding, the voice of the iconic Metal Gear character, Colonel Campbell, and a host of other notable characters from Transformers to Fallout.

In an ironic twist, Eiding, whose Metal Gear Solid character, Colonel Roy Campbell, was famously replaced by a rogue AI in the 2001 sequel "Sons of Liberty," finds himself grappling with a similar issue off-screen. The actor vehemently condemned those using AI tools to recreate his distinctive voice without consent.

Eiding took to Twitter stating, "If you do not have written permission to use my voice, you DO NOT HAVE PERMISSION to use my voice, including AI use. Doing so is a violation of my legal rights and a real slap in the face."

Eiding now joins fellow voice actor, Erica Lindbeck, who's known for her roles as Futaba Sakura in Persona 5, Hrist in God of War Ragnarok, and Blaze the Cat in the Sonic the Hedgehog series, for being vocal about the unauthorized AI exploitation of her voice work. Lindbeck was compelled to delete her Twitter account following a bitter dispute with an AI creator who used her voice in an AI-generated cover of Bo Burnham's "Welcome to the Internet." While the creator deemed the video a "dumb but harmless Futaba AI cover," Lindbeck and many others saw it as an infringement of her rights.
