After Stephen Hawking's innovative communication methods, a new era of brain-computer-interface (BCI) technology is emerging, enabling faster and more expressive speech. Researchers at UC Davis developed a neural prosthesis capable of translating brain signals directly into phonemes and words, moving beyond the limitations of previous systems that relied on text-based output. This technology allows individuals with paralysis to not only articulate words but also manage their speech dynamics, improving their ability to communicate fluently and expressively.
"Our main goal is creating a flexible speech neuroprosthesis that enables a patient with paralysis to speak as fluently as possible, managing their own cadence, and be more expressive by letting them modulate their intonation," says Maitreyee Wairagkar, a neuroprosthetics researcher at UC Davis who led the study.
The recent brain-computer-interface devices had significant latency, restricting users to predefined vocabulary, which hindered their ability to express subtleties of spoken language.
