AlterEgo is a wearable peripheral neural interface that allows humans to converse in natural language with machines, artificial intelligence assistants, services, and other people by articulating words internally without any voice or observable movements. Audio feedback via bone conduction makes the system closed-loop without disrupting the user's usual auditory perception. While people with speech disorders are the obvious user base, AlterEgo also helps augment the human interaction of all groups of people.

I am designing custom hardware and electronics for high-resolution data acquisition to obtain cleaner signals and identify better correlates to internally articulated words to increase the accuracy and dictionary size.

I am also designing a minimal auditory feedback extension to the device using bone conduction and wireless communication.
