该研究于 2025 年 6 月 12 日发表于 国际顶尖学术期刊 Nature ,论文题为: An instantaneous voice-synthesis neuroprosthesis ,论文作者来自加州大学戴 维斯分校。 该研究利用植入式 脑机接口 (BCI) ,结合 低延迟处理和 AI 驱动的解码模型,将一位已瘫痪的 渐冻症 (ALS) 患者大脑中的神经活动转化为语言,并通过扬 声器实时合成并输出 (仅延迟 8.5 毫秒) ,从而帮助他实现流畅、且有感情地" 说话甚至唱歌 "。 研究团队将 脑机接口 (BCI) 植入到一名已经几乎完全失去发音能力的 渐冻症 (ALS) 患者的大脑,通过 256 个微电极记录负责语言运动功能的 腹侧中央前 回 的神经活动,并实时合成语音,通过 闭环音频反馈进行调整 ,克服了训练神经解码器时缺乏真实语音的难题,成功准确合成了他的声音。除了语音内容,研 究团队还从大脑神经活动中解码出了副语言特征,使患者能够实时调节其脑机接口合成的声音,从而改变语调并哼唱简短的旋律。这项临床研究 表明, 通过脑机 接口让瘫痪者清晰且富有感情地说话是可行的 。 撰文丨王聪 编辑丨王多鱼 排版 ...
脑机接口首次让语言障碍患者实现说话唱歌
财联社· 2025-06-13 14:30
在症状出现5年后,这名男子接受了手术,在控制运动的大脑区域插入256个硅电极,每个长 1.5毫米。论文作者之一、美国加利福尼亚大学戴维斯分校的Maitreyee Wairagkar和同事训 练了深度学习算法,能够每10毫秒捕捉一次大脑中的信号。团队的系统实时解码了该男子试 图发出的声音,而不是他想要表达的具体词语或基本音素——构成单词的语音亚单位。 一名患有严重语言障碍的男子,借助大脑植入装置,能够富有表现力地说话和歌唱。 该装置 可以将他的神经活动转化为话语,不仅能实现语调变化,强调他选择的单词,还能让他以3个 音调哼唱一串音符。 该系统被称为脑机接口(BCI),使用人工智能解码参与者说话时的脑电活动。该装置是第一 个不仅能再现一个人的意图,还能复制自然语言特征的BCI。而音调、音高、重音等自然语言 特征有助于表达意思和情感。 在一项研究中,一种模仿参与者声音的合成声音,在他的神经活动发出说话意图信号的10毫 秒内就说出了他的话。这项6月11日发表于《自然》的研究成果标志着对早期BCI的重大改 进。早期BCI通常在3秒内输出语音,或者仅在用户模拟完整个句子后才能生成语音。 "这是语音BCI领域的圣杯。"荷兰 ...

【广发宏观郭磊】4月BCI数据初步显示外需影响
郭磊宏观茶座· 2025-04-27 09:26
广发证券首席经济学家 郭磊 guolei@gf.com.cn 摘要 第一, 2025年4月中国企业经营状况指数(BCI)为50.1,环比下行4.7个点。今年1-3月这一指标连续改 善,反映一季度微观状况的逐步好转,4月属于年内首次回踩。BCI数据在指标设计上已经结合同比,所以季 节性特征并不明显,过去10年同期的环比均值为-0.7,剔除 2022年极值为0.4,4.7个点的环比下行幅度显 然相对偏大,我们理解主要来自关税的影响。 第二, 销售前瞻指数和利润前瞻指数分别为57.3、47.7,环比下行7.8个点和1.7个点,销售的调整幅度相对 更为明显。我们理解这主要源于PPI和利润率本身已经处于周期低位;叠加企业对外部环境变化有一定预期, 可能同步进行成本和费用的收缩。 第三, 与这一情况对应的是,企业库存前瞻指数环比大幅下行5.3个点,即企业在外部环境存在较大不确定性 的情况下,未来审慎预留合意库存水平。这实际上也是没有预期的需求变化和有预期的需求变化之间的区别。 如果是毫无征兆的需求变化,企业生产端来不及调整,库存会被动上升,比如2020年2月,库存指标大幅上 行3.3个点;如果是有一定预期的需求变化,企业 ...
