AI transcribes words users 'speak silently'

The new technology works by electrodes being fitted to the face and jaw of the user, designed to pick up otherwise undetectable neuromuscular signals. These slight muscle movements are triggered by internal verbalizations, that is when a person thinks what they are saying rather than actually verbalizing. When a person says words'in their head' any muscle movement cannot be seen with the human eye. It is, as the new research demonstrates, possible to detect this with the aid of artificial intelligence. The technology comes from the Massachusetts Institute of Technology, and it uses machine-learning system to correlate particular signals with particular words.
