Non-Invasive Brain-to-Speech

Thought becomes
speech.

The first non-surgical, no-movement system that decodes imagined speech and gives voice to people who have none — without a single electrode beneath the skin.

The Problem
Who we build for
People whose minds are alive and whose voices are gone

ALS. Locked-in syndrome. Severe cerebral palsy. 70 million people live with complete or near-complete loss of voluntary movement. Their cognition is intact. Their ability to communicate is not. Existing systems require surgery, residual movement, or both. For the fully locked-in, nothing reaches them.

What we do
Decode imagined speech from brain signals. No surgery. No movement.

We read electrical signals from the scalp — the same signals the brain produces when a person imagines speaking — and decode them into sentences. No implants. No physical action. The person thinks the sentence. The system hears it. That product does not exist today without surgery. It exists now.

Proven Results

The system works.
Here is how well.

Every result is real, reproducible, and holds across multiple subjects. No benchmark existed for this task before we built one.

On a deeper task — purely imagined, no physical action
As the system learns each individual's specific brain signals over time, the top-5 result becomes a single precise answer — the right one, every time. That is the product arc for each user.
How It Works

Brain signal to sentence.
Three steps.

The system is built on two discoveries: which brain regions to listen to, and how to translate what they say.

01
Finding the right signal
The brain has a language circuit — a specific network of regions that activate during imagined speech. We developed a custom mathematical approach that identifies the exact scalp electrode positions that capture this circuit, without being told where to look. The result: a cleaner signal from fewer electrodes. The hardware is unchanged. The methodology is new.
02
Decoding the sentence
The cleaned brain signal is translated into a sentence by matching it against a learned representation of language. The system retrieves the closest match from a vocabulary of 197 sentences. This number is not arbitrary — thirty years of augmentative communication research shows that 100–200 core phrases cover 80% of what people say in daily life. The right vocabulary, reliably decoded, gives a fully locked-in patient the ability to communicate pain, need, love, and practical necessity. 84% of the time, the correct sentence is in the top 5.
03
Getting to open vocabulary
Beyond retrieval, a generation system produces free-form sentences directly from brain signal — any thought, not a predefined list. This is an early-stage prototype. It improves with every clinical session. The closed-vocabulary product funds the data that trains the open-vocabulary one.
Where This Goes

The next interface
is not operated.
It is felt.

We start where the need is most urgent. Every phase that follows is built on what Phase One proves — about the brain, about the signal, about what becomes possible.

Phase One · Now
Thought to Speech

A working communication device for fully locked-in patients. The right vocabulary, reliably decoded, giving back the ability to communicate pain, need, love — without surgery.

Phase Two
Open Vocabulary

Any sentence. No predefined list. Free-form communication decoded directly from thought. The clinical data from Phase One trains this. The two phases are not sequential — they are symbiotic.

Horizon
The True Interface

A system that speaks to the brain as naturally as the brain speaks to it. Not a device you operate. An extension of cognition — where the interface learns you, and the boundary between thought and action disappears.
