"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.
"In the wake of a long-haul injury, the importance of outside design perspectives cannot be overstated, as they may highlight overlooked problems and reveal useful solutions."
"Vision is not just an assistive device, but a companion that supports visually impaired individuals in becoming independent and maintaining their self-esteem," the designers note.
The robot quickly learned how each individual reacted and was very effective in understanding intention and mimicking movements. The patients all said interacting with the robot was a motivational experience.
