Earlier this year, New Hampshire voters experienced this firsthand when a deepfake mimicking President Joe Biden’s voice urged them to skip the polls ahead of the primary. The deepfake likely needed only several seconds of the president's voice to create the clone. According to multiple AI voice cloning models, about 10 seconds of an actual voice is all that is needed to recreate it. And that can easily come from a phone call or a video from social media. "A person's voice is really probably not that information-dense. It's not as unique as you may think," James Betker, a technical staff member at OpenAI, told Scripps News. Betker developed TortoiseTTS, an open-source voice cloning model. "It's actually very easy to model, very easy to learn, the distribution of all human voices from a fairly small amount of data," Betker added. How AI voice cloning works AI models have been trained on vast amounts of data, learning to recognize human speech. Programs analyze the data and train repeatedly, learning characteristics such as rhythm, stress, pitch and tone. "It can look at 10 seconds of someone speaking and it has stored enough information about how humans speak with that kind of prosody and pitch. Enough information about how people speak with their processing pitch and its weights that it can just continue on," Betker said. Imagine a trained AI model as a teacher, and the person cloning the voice to be a student. When a student asks to create a cloned voice, it starts off as white noise. The teacher scores how close the student is to sounding correct. The student tries again and again based on these scores until the student produces something close to what the teacher wants. While this explanation is extremely simplified, the concept of generating a cloned voice is based on bit-by-bit, based on probability distributions. "I think, at its core, it's pretty simple," Betker said. "I think the analogy of just continuing with what you're given will take you pretty far here." There are currently some AI models that claim to only need two seconds of samples. While the results are not convincing yet, Betker says future models will need even fewer voice samples to create a convincing clone.
Olive Garden diner finds serial number printed on her breadsticks — and gets paid for the snafu
KNOXVILLE, Tenn. (AP) — Sara Puckett had 17 points and Ruby Whitehorn scored 16 as No. 15 Tennessee walloped Winthrop 112-50 on Sunday, earning the Lady Volunteers the seventh 12-0 start to a season in program history. Puckett made 6 of 10 shots with a 3-pointer and all four of her free throws, adding eight rebounds for Tennessee, which is unbeaten through 12 games in its first season under head coach Kim Caldwell — and for just the second time in the past 19 seasons. Whitehorn made 7 of 13 from the floor and both of her foul shots. Jewel Spear hit three 3-pointers and scored 15 for the Lady Vols. Kaniya Boyd scored 15 off the bench on 5-for-5 shooting with a 3-pointer. Zee Spearman added 14 points and reserve Tess Darby scored 10. Amourie Porter made all eight of her free throws and scored 14 to lead the Eagles (6-7), who fell to 1-5 on the road. Eight different players scored as Tennessee led 35-13 after one quarter. Spear and Puckett each had nine points by halftime and Whitehorn scored eight as the Lady Vols took a 61-32 advantage into intermission. Tennessee added eight points to its lead after three quarters and outscored Winthrop 31-4 in the final period. Tennessee entered play leading the nation in scoring average (97.4), 3-pointers made per game (12.6) and attempted per game (38.3) as well as offensive rebounds per contest (21.5) and turnovers forced (27.2). It was the sixth time the Lady Vols have scored at least 100 this season. Tennessee opens Southeastern Conference play on Thursday at Texas A&M.

The latest development came hours after thousands of his supporters, defying government warnings, broke through a barrier of shipping containers blocking off Islamabad and entered a high-security zone, where they clashed with security forces, facing tear gas shelling, mass detentions and gunfire. Tension has been high in Islamabad since Sunday when supporters of the former PM began a “long march” from the restive north-west to demand his release. Khan has been in a prison for more than a year and faces more than 150 criminal cases that his party says are politically motivated. Khan’s wife, Bushra Bibi, led the protest, but she fled as police pushed back against demonstrators. Hundreds of Khan’s supporters are being arrested in the ongoing night-time operation. Interior minister Mohsin Naqvi told reporters that the Red Zone, which houses government buildings and embassies, and the surrounding areas have been cleared. Leaders from Khan’s Pakistan Tehreek-e-Insaf party, or PTI, have also fled the protest site. Earlier on Tuesday, Pakistan’s army took control of D-Chowk, a large square in the Red Zone, where visiting Belarusian President Alexander Lukashenko is staying. Since Monday, Mr Naqvi had threatened that security forces would use live fire if protesters fired weapons at them. “We have now authorised the police to respond as necessary,” Mr Naqvi said Tuesday while visiting the square. Before the operation began, protester Shahzor Ali said people had taken to the streets because Khan had called for them. “We will stay here until Khan joins us. He will decide what to do next,” Mr Ali said. Protester Fareeda Bibi, who is not related to Khan’s wife, said people have suffered greatly for the last two years. “We have really suffered for the last two years, whether it is economically, politically or socially. We have been ruined. I have not seen such a Pakistan in my life,” she said. Authorities have struggled to contain the protest-related violence. Six people, including four members of the security services, were killed when a vehicle rammed them on a street overnight into Tuesday. A police officer died in a separate incident. Dozens of Khan supporters beat a videographer covering the protest for the Associated Press and took his camera. He sustained head injuries and was treated in hospital. By Tuesday afternoon, fresh waves of protesters made their way unopposed to their final destination in the Red Zone. Mr Naqvi said Khan’s party had rejected a government offer to rally on the outskirts of the city. Information minister Atta Tarar warned there would be a severe government reaction to the violence. The government says only the courts can order Khan’s release. He was ousted in 2022 through a no-confidence vote in Parliament. In a bid to foil the unrest, police have arrested more than 4,000 Khan supporters since Friday and suspended mobile and internet services in some parts of the country. Messaging platforms were also experiencing severe disruption in the capital. Khan’s party relies heavily on social media and uses messaging platforms such as WhatsApp to share information, including details of events. The X platform, which is banned in Pakistan, is no longer accessible, even with a VPN. Last Thursday, a court prohibited rallies in the capital and Mr Naqvi said anyone violating the ban would be arrested. Travel between Islamabad and other cities has become nearly impossible because of shipping containers blocking the roads. All education institutions remain closed.AP News Summary at 2:48 p.m. EST
