Description
Dr. Edward Chang from UCSF discusses different types of neuroprosthetics, as well as his research into BCI's and synthesized speech, where neural signals are translated into text using input from the muscles in the vocal tract. He explains:

"Because our paralyzed volunteers can’t speak while we watch their brain patterns, we asked our first volunteer to try two different approaches. He started with a list of 50 words that are handy for daily life, such as “hungry,” “thirsty,” “please,” “help,” and “computer.” During 48 sessions over several months, we sometimes asked him to just imagine saying each of the words on the list, and sometimes asked him to overtly try to say them. We found that attempts to speak generated clearer brain signals and were sufficient to train the decoding algorithm. Then the volunteer could use those words from the list to generate sentences of his own choosing, such as “No I am not thirsty.”"
