Paradromics Achieves Real-Time Speech Decoding with Brain Implant
By Drooid · · How we work
Breakthrough Demonstration
Paradromics, an Austin-based neurotechnology firm, reported that its Connexus brain-computer interface enabled a Michigan woman with a progressive motor-neuron disease to generate her own words, answer open-ended questions, and hold a live phone conversation with her grandchildren. The participant’s first freely chosen decoded sentence was “Okay, I have a lot to say.” The system translated neural activity into text and synthesized speech without errors, moving the trial beyond researcher-selected phrases to genuine, spontaneous communication.
How the Implant Works
Connexus is a surface-mounted array roughly the size of a dime, equipped with 421 platinum-iridium micro-wires that record signals from individual neurons. In June, neurosurgeon Dr. Matthew Willsey and his University of Michigan team performed a four-hour surgery, creating an inverted U-shaped incision, opening a craniotomy, and positioning the array in the precentral gyrus—the motor cortex region that controls speech muscles. A lead runs under the skin to a chest-mounted power-and-data unit, which wirelessly transmits signals to an external receiver. Software decodes the recorded patterns into text and synthesized voice in real time, allowing the participant to communicate from her home weeks after implantation.
Official Statements & Responses
Paradromics CEO Matt Angle said the June implantation marked the transition to long-term human use and that the trial will monitor safety, durability, and real-world usefulness for six years. He emphasized that the device can extract users’ intentions and provide an assistive communication tool that outperforms non-implant options. Dr. Willsey expressed optimism that successful outcomes could substantially advance the field and noted the precise placement of the array was critical for capturing speech-related neural activity. The company is recruiting additional participants for the FDA-approved Connect-One early feasibility study.
