Brain Implant Enables Thought‑Generated Speech for Severely Impaired Woman

Key Takeaways

• Neurotechnology startup Paradromics reported that its wireless brain implant allowed a 68‑year‑old woman with severe speech impairment to engage in real‑time conversation.
• The system translates brain signals into a computer‑generated voice.
• She was the first participant in Paradromics’ clinical trial, and the company plans to enroll ten patients nationwide.

Paradromics, a neurotechnology startup founded in 2015 by CEO Matt Angle, announced that a woman with a severe neurological condition used its brain implant to engage in real‑time conversation via a computer‑generated voice.

The 68‑year‑old, unnamed Michigan patient, who has lost most of her speech ability, was able to communicate spontaneously, even during phone calls with her grandchildren, according to The New York Times.

Brain‑computer interfaces (BCIs) employ implanted electrodes to capture neural signals, which are then translated into words by artificial intelligence.

When the patient attempted to speak, the implant detected the associated brain activity. This information was transmitted wirelessly to a computer, which displayed and spoke the words aloud, and the system also functioned when she merely imagined speaking, without moving her speech muscles.

Experts told The Times that the wireless system represents a key advance toward making brain implants practical for everyday use, as it eliminates the need for a tethered computer connection.

The patient was the first to receive the implant

She became the first participant in Paradromics’ clinical trial to receive the Connexus brain‑computer interface, which contains more than 400 electrodes; the device was implanted at University of Michigan Health in June.

Paradromics intends to enroll ten patients nationwide in a clinical trial targeting individuals with paralysis‑related speech and movement difficulties, such as stroke or amyotrophic lateral sclerosis, said Dr. William Marks, the company’s chief clinical officer.

The patient suffers from primary lateral sclerosis, a condition that damages the nerve cells responsible for speaking, swallowing, and walking. Although she can still move some speech muscles, her words are often unclear to others, Marks noted.

Angle explained that the device can distinguish various brain activity patterns associated with communication, stating, “We can detect the representation of words and phonemes whether she attempts to speak, imagines speaking, or simply listens,” according to The Times.

In a Paradromics video, researchers invited the woman to say anything she wished. She smiled, attempted to speak slowly, and, despite difficulty articulating, the system promptly rendered her words as a computer voice: “Okay, I have a lot to say.”

Dr. Edward Chang, chairman of neurological surgery at the University of California, San Francisco, has long focused on advancing brain‑computer interface technologies. Although he did not participate in the Paradromics trial, he praised the company’s breakthrough work.

“Their demonstration brings us one step closer to clinical reality for restoring speech communication in individuals with severe paralysis,” Chang told The Times.
