A woman with severe paralysis from a brainstem stroke can speak through a digital avatar following the development of a brain-computer interface at UC San Francisco and UC Berkeley.
Ann Johnson, a former teacher from Regina, is the first person in the world to speak out loud via decoded brain signals.

Two new papers show major advances in the effort to translate brain activity into speech.
Speech neuroprostheses have the potential to restore communication to people living with paralysis, but naturalistic speed and expressivity are elusive1. Here we use high-density surface recordings of the speech cortex in a clinical-trial participant with severe limb and vocal paralysis to achieve high-performance real-time decoding across three complementary speech-related output modalities: text, speech audio and facial-avatar animation. We trained and evaluated deep-learning models using neural data collected as the participant attempted to silently speak sentences. For text, we demonstrate...
