The Youtube description of AlterEgo:

AlterEgo is a wearable system that allows a user to silently converse with a computing device without any voice or discernible movements — thereby enabling the user to communicate with devices, AI assistants, applications, or other people in a silent, concealed, and seamless manner. A human user could transmit queries, simply by vocalizing internally (subtle internal movements) and receive aural output through bone conduction without obstructing the user’s physical senses and without invading a user’s privacy. AlterEgo aims to combine humans and computers—such that computing, the internet, and AI would weave into human personality as a “second self” and augment human cognition and abilities.
