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。

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
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.
