  "account": "Pindrop's blog post appeared the day before. Voters in New Hampshire received an AI-generated robocall impersonating President Biden before the 23 January 2024 primary. Pindrop, a company that builds synthetic-audio detection tools, analyzed a 39-second clip, checking its patterns against more than 120 voice synthesis engines. Its CEO Vijay Balasubramaniyan told WIRED the result came back well north of 99 percent for ElevenLabs. Hany Farid's UC Berkeley team, initially skeptical, ran its own model on the same sample. It concluded with high confidence that it was AI-generated and likely ElevenLabs. ElevenLabs' own detector returned 84 percent, a result WIRED reproduced. In May 2024 the New Hampshire Attorney General announced 26 charges against Steven Kramer and the FCC proposed a $6 million fine (NHPR). The sources do not connect those actions to Pindrop's analysis.",

Its CEO Vijay Balasubramaniyan told WIRED the result came back well north of 99 percent for ElevenLabs. Hany Farid's UC Berkeley team, initially skeptical, ran its own model on the same sample. It concluded with high confidence that it was AI-generated and likely ElevenLabs. ElevenLabs' own detector returned 84 percent, a result WIRED reproduced. In May 2024 the New Hampshire Attorney General announced 26 charges against Steven Kramer and the FCC proposed a $6 million fine (NHPR).
