Could a speech implant pick up words its user never meant to say aloud?

A study of four people with speech implants in motor cortex found that imagined sentences could be decoded in real time, and that some free-form inner speech could also be decoded while participants recalled sequences or counted silently. The same study demonstrated ways to prevent it, among them keeping decoding locked until the user imagines a chosen keyword. It is direct evidence that a device built to restore communication can capture more than the user means to share, which turns mental privacy into a design requirement for speech implants.
