Synopsis: Speech decoding from a small set of spatially segregated minimally invasive intracranial EEG electrodes with a compact and interpretable neural network. Millions of people worldwide are affected by speech disorders limiting their communication ability. Causes of speech loss can vary and include stroke and certain congenital conditions. Speech neuroprostheses-brain-computer interfaces capable of decoding speech based on brain activity can provide an accessible and reliable solution for restoring communication to such patients.

Definition

Neuroprosthetics

Neuroprosthetics (neural prosthetics) is a discipline in neuroscience and biomedical engineering concerned with developing neural prostheses. They are sometimes contrasted with a brain-computer interface, which connects the brain to a computer rather than a device to replace missing biological functionality.

Main Digest

Researchers from HSE University and the Moscow State University of Medicine and Dentistry have developed a machine learning model that can predict the word about to be uttered by a subject based on their neural activity recorded with a small set of minimally invasive electrodes. The paper ‘Speech decoding from a small group of spatially segregated minimally invasive intracranial EEG [...]
