Silent speech no more: new device reads muscle signals to restore voice
NCT ID NCT05479643
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new device that uses muscle signals from the face and neck to recognize silent speech and turn it into voice. It is for adults who have lost their voice due to laryngectomy or severe voice problems. The goal is to see if the device can accurately identify words and numbers, and how users feel about it.
