Brain-Computer Interfaces for Real-Time Speech Synthesis from Neural Signals

Quick fact

In 2023, researchers demonstrated a brain-computer interface that allowed a woman with paralysis to speak at a rate of 62 words per minute, three times faster than previous systems, using a digital avatar that also mimicked her facial expressions.

Why this is interesting

Imagine being able to speak just by thinking—no air, no vocal cords, no mouth movement. For people with severe paralysis, this leap might be closer than you think.
