China Focus: Brain-computer interface makes breakthrough by deciphering Chinese speech in brain
Summary
NeuroXess reported two clinical trial milestones: its flexible BCI decoded precise intended movements in real time for one patient, and decoded Chinese speech in real time for another. A 256-channel device was implanted at Huashan Hospital. The patient achieved 71% speech decoding accuracy for 142 Chinese syllables within five days, with single-character decoding latency under 100 milliseconds.
Why it matters
Real-time Chinese speech decoding requires fundamentally different approaches than alphabetic languages due to Chinese's monosyllabic, tonal nature. This breakthrough opens possibilities for direct brain-to-AI communication and could transform care for patients with ALS, stroke, and spinal cord injuries.
