- Neuroscientists are advancing technology to convert brainwaves into speech for people unable to speak.
- Researchers at universities and companies like Precision Neuroscience are using brain implants and AI to generate naturalistic speech.
- Investment has traditionally focused on implants for operating keyboards or robotic limbs, but some labs are now prioritizing speech conversion.
- Edward Chang, a neurosurgeon at UCSF, highlights progress in making brain-to-synthetic voice as fluent as natural conversation.
- A recent study with a quadriplegic woman reduced the lag between brain signals and audio output from 8 seconds to 1 second.
- The system achieved a median decoding speed of 47.5 words per minute, about a third of normal conversation speed.
