Neurotech 2023 was very exciting but nothing was said about Amyotrophic Lateral Sclerosis . . . until the last talk, which featured

Sergey Stavisky, Ph.D., UC Davis and their neuroprosthetics lab
Sergey Stavisky – Neuroscientist and neural engineer

which is a member of the BrainGate consortium

who presented a case of a patient with four brain implants . . .

and focused on the use of brain voice signals and artificial speech using the patient's own (prior) voice as heuristic in restoring patient's voice via artificial generation; the result was good in quality and accuracy, though on the slow side in the neighborhood of twenty words per minute (speech is normally a little over one hundred words per minute). Achievement was stable relative to patient's regressing abilities and he expects qualitative loss would not occur during course of disease but nevertheless, the syndrome continues regression until the patient's death (as usual).
