Paper Research: Five Points About Alterego

AlterEgo is a wearable silent speech interface that enables a discreet, seamless and bi-directional communication with a computing device in natural language without discernible movements or voice input.

There are five overviews to distinguish Alterego system based on the following points:

1. The system captures neuromuscular signals from the surface of the user's skin via a wearable mask.

2. Alterego's system performs robustly when the user does not open their mouth, make any sound and without the need for any deliberate and coded muscle articulation that is often used when using surface EMG to detect silent speech. Since the existing non-invasive real-time methods with robust accuracies require the user to explicitly mouth their speech with pronounced, apparent facial movements. It is the key difference between Alterego and the existing systems. The modality of natural language communication without any discernible movement is key since it allows for a seamless and discreet interface.

3. Alterego's system achieves a median accuracy of 92%, outperforming amongst others.

And it's based on the silent input without required any facial muscle movement.

4. The device is portable and ambulatory wearable, which a user just needs to wear for it to function and the device connects wirelessly over Bluetooth to any external computing device.

5. The platform does not have access to private information or thoughts. Inputs are voluntary on the user's part, which is unlike traditional brain-computer interfaces. The system has a

peripheral nerve interface by taking measurements from the facial and neck area, which allows for silent speech signals to be distilled without being accompanied by electrical

noise from the frontal lobe of the cerebral cortex.
