Researchers develop world's first thought-based 'brain-to-text' system
By HealthInnovations
Speech is produced in the human cerebral cortex and previous studies have shown that the brain waves associated with speech processes can be directly recorded with electrodes located on the surface of the cortex. Now, researchers from the KIT and Wadsworth Center have shown for the first time that is possible to reconstruct basic units, words, and complete sentences of continuous speech from these brain waves and to generate the corresponding text. In effect the team have developed the world’s first working ‘Brain-to-Text’ system. The study is published in the journal Frontiers in Neuroscience.
The researchers state that it has long been speculated whether humans may communicate with machines via brain activity alone. As a major step in this direction, the current study’s results indicate that both single units in terms of speech sounds as well as continuously spoken sentences can be recognized from brain activity.
In the current study the brain activity was recorded from 7 epileptic patients, who participated voluntarily in the study during their clinical treatments. An electrode array was placed on the surface of the cerebral cortex (electrocorticography (ECoG)) for their neurological treatment. While patients read aloud sample texts, the ECoG signals were recorded with high resolution in time and space. Later on, the researchers analyzed the data to develop Brain-to-Text...
