AI突破：脑电波转化为语音助力瘫痪患者发声
加州大学伯克利分校和旧金山分校研究团队开发出革命性AI系统，能够实时将瘫痪患者的脑电波转化为自然语音，且保留患者原声音特征。该技术通过神经义肢采集大脑运动皮层的神经活动，并由AI将其解码为语音，处理延迟仅1秒，较2023年的研究成果缩短了7秒。
系统支持多种脑信号采集设备，包括高密度电极阵列、穿透脑表面的微电极以及非侵入式表面肌电图传感器。研究团队使用患者受伤前的声音样本训练文本到语音模型，通过让患者默读屏幕单词来映射神经活动与语言的关系。
研究人员表示，该技术能显著改善瘫痪及ALS患者的生活质量，未来将致力于加快AI处理速度并使输出语音更具表现力。

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
Telegram has no known backdoors and, even though it is come in for criticism for using proprietary encryption methods instead of open-source ones, those have yet to be compromised. While no messaging app can guarantee a 100% impermeable defense against determined attackers, Telegram is vulnerabilities are few and either theoretical or based on spoof files fooling users into actively enabling an attack.
