Wearable device, AlterEgo, can read words spoken internally

A wearable device called AlterEgo has been created that can transcribe words spoken by a user internally, but not loud.

The device uses electrodes that pick up the signals that are generated when internal verbalizations take place.

Scientists at the Massachusetts Institute of Technology (MIT) in the United States have developed the revolutionary device.

This internal vocalization is a method of speech that is not heard or seen by others.

The device is worn on the face of the user so that it can detect the muscle movements.

The signals are fed to a computer system that is trained to correlate particular signals with particular words.

The information is then passed on to the users via bone-conduction.

Although the device is quite big in size at present, it may evolve in the future into more compact designs.
