A banana duct-taped to a wall has sold for £4.9 million – part of the evolving relationship between art and financeVoice cloning is an emerging technology powered by artificial intelligence and it's raising alarms about its potential misuse. 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.x99bet 。

NoneMANCHESTER, England (AP) — Manchester City’s players were booed by their own fans Tuesday after blowing a three-goal lead against Feyenoord in the Champions League to extend their winless run to six games. Jeers rang around the Etihad Stadium after the final whistle of a dramatic 3-3 draw. “They are disappointed. Of course we understand it,” City manager Pep Guardiola said. “They are completely right to express what they feel.” After five-straight losses in all competitions, City looked to be cruising to victory after going three up inside 50 minutes. But Feyenoord mounted an improbable comeback and leveled the game in the 89th to leave the home crowd stunned. While the worst losing streak of Guardiola’s managerial career was brought to an end, his wait for a first win since Oct. 26 goes on. Erling Haaland had scored twice, with Ilkay Gundogan also on target to put City in control. But goals from Anis Hadj Moussa in the 75th, Santiago Gimenez in the 82nd and David Hancko in the 89th turned the game on its head. According to stats supplier Opta, it was the first time in Guardiola's managerial career that his team had failed to win a game after leading 3-0. It said it was the first time City had failed to win from that position since 1989. “We lost a lot of games lately, we are fragile and of course we need a victory," Guardiola said. “The game was good for the confidence, we were playing a good level, but the first time something happened we had problems.” A win would have moved City up to fifth in the Champions League standings , but the draw left it 15th with three games remaining in the first phase of the competition.

City’s players, including Bernardo Silva, Josko Gvardiol and Haaland looked visibly frustrated as they left the field to cheers from the delirious traveling Dutch fans in the away section of the stadium. “If you are 3-0 up at home you can never give it away like this. It is what it is at the moment. The only thing we can do is fight back and stay strong,” City defender Nathan Ake said. City plays Premier League leader Liverpool on Sunday — defeat would leave it 11 points adrift of its title rival. “We will learn for the future. It has been and will be a tough season for us and we have to accept it," said Guardiola, who had a cut on his nose during the game. He said it had been caused when he scratched it with his fingernail. James Robson is at https://twitter.com/jamesalanrobson AP soccer: https://apnews.com/hub/soccer
