Abstract: A real-time in-ear EEG signal verification system. The system includes an in-ear device (IED) configured to be placed within an ear canal of a user and a controller. The IED includes a speaker configured to present a calibration audio signal to the user, the calibration audio signal being embedded with a predetermined audible feature, and an in-ear electrode configured to be in contact with an inner surface of the ear canal. The controller is configured to instruct the speaker to present the calibration audio signal to the user, and generate neural signal data based on electrical signals from the in-ear electrode. The electrical signals correspond to brain activity of the user in response to the predetermined audible feature. The controller is configured to determine a quality of the generated neural signal data, and perform an action based on the quality of the neural signal data.
