    2025年6月11日,美国加州大学戴维斯分校发表于《Nature》的研究显示,脑机接口(BCI)系统利用人工智能来解码使用者试图说话时的脑电活动,可以帮助一名患有严重言语障碍的男子能够富有表现力地说话和唱歌。
    该装置不仅是第一个能再现人的意图,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。一名患上肌萎缩侧索硬化症的45岁男性植入了该设备,在其发出有说话意图的神经活动信号后10 ms内便可以说出话语,还能以3种音高哼唱出一串音符。
    “这是语音BCI领域圣杯。”荷兰马斯特里赫特大学计算神经科学家Christian Herff说,“这是真实的、自发的、连续的讲话。”
    该团队还通过训练人工智能算法,根据患者生病前的采访录音,将合成声音个性化,使其听起来像患者自己的声音。研究人员要求参与者尝试发出“啊”“哦”“嗯”之类的感叹词,并说出虚构的单词。BCI成功产生了这些声音,表明它可以在不需要固定词汇的情况下生成语音。
    使用该装置,这名男子可以拼写单词、回答开放式问题,并使用解码器训练数据之外的一些单词说出他想说的话。该男子告诉研究人员,合成的声音说话让他“感到高兴”,感觉就像他的“真实声音”。
    尽管该系统取得了突破性进展,但研究人员指出,脑机接口技术的广泛应用仍面临电极植入手术风险、设备的长期稳定性和耐用性、如何保护用户隐私和数据安全等诸多挑战。
