On June 24, Beijing time, on Wednesday, local time, Amazon AI voice digital assistant Alexa created a sensation on the Internet by imitating the humanized presentation of any sound. People are worried about whether there may be false sounds, for example, using legal recordings to imitate what people say they have not actually said, to commit kidnapping fraud or forge audio in major decisions of the company. Local Wednesday, Amazon senior vice president Rohit? Rohit Prasad revealed that his company is developing a system that enables AI voice digital assistant Alexa to imitate any sound after hearing less than one minute of audio. When the news about the research and development of this technology was released, people simply thought of its benefits. Rohit Prasad, Alexa's chief scientist, also fully demonstrated the humanization of digital assistants in the company presentation on Wednesday, demonstrating the picture of Alexa pretending to be a grandmother to read the excerpts from the wizard of oz. He said that human characteristics such as empathy and emotion are the key to building trust with people. "During the period when the epidemic continues, when we lose our loved ones, these attributes become more important." although artificial intelligence can not eliminate the pain of loss, it can definitely make their memories last forever. " The demonstration gave the impression that the technology was used as a tool for digital resurrection of the dead. But Prasad said at the Amazon technology conference held in Las Vegas that the main purpose of the service was not to simulate the voice of the dead. As the demonstration was discussed on the Internet, it caused a great sensation. At the same time, there were some voices expressing concern about whether legal recordings would be used to imitate what people said they didn't actually say. Siwei Lyu, Professor of computer science and engineering at the University of buffalo, said he was concerned about the development of deep forgery and digital media forensics, "The voice conversion technology developed by Amazon is certainly beneficial, but we should be aware of the potential misuse. For example, kidnappers can disguise themselves as family members or friends on the phone to lure unsuspecting victims, or senior managers may forge recordings when making statements about the company's financial situation, which may cause problems in the stock market." Although Amazon did not disclose when Alexa's new features will be launched, similar technologies may make this kind of prank much easier. Prasad said that Amazon has learned to simulate sound based on people's speech in less than a minute, which used to be done in the studio. (Xinhua News Agency)
