Brain-computer interfaces (BCIs) can restore communication for people who have lost their speech to a stroke or neurological disease. But these experimental systems, which combine sensors placed in the brain with algorithms that turn the neural signals of attempted speech into words, have so far been developed mostly for English speakers.
BCIs for Mandarin Chinese, a tonal language in which stark changes in pitch distinguish the meanings of words, have lagged. Last year in Science Advances, a group of researchers in Shanghai reported success in “decoding” Mandarin speech from the neural signals of a healthy person as she spoke—and, in a first, generated Chinese text onscreen in real time.
