Prof Greger is confident his team will soon be able to build a voice box that repeats the words a person thinks.
It could work because the same brain signals are believed to be produced when a person thinks a word as when they say it out loud.
"Scientists are now able to listen to signals from individual nerve cells in particular regions of the brain.
"The challenge is developing the computer software that can accurately interpret the complex pattern of electronic pulses.
"It's like learning a new language and, so far, the scientists can only decipher a very basic vocabulary.
"Other researchers are using the same brain-reading technique in the movement-control centre of the brain, with the hope of helping paralysed patients.
"So this new science of neural engineering has huge potential."
For people who are paralysed, the development offers real hope because often their brains are healthy and produce the same signals as able bodied people, but they do not reach their muscles because of their injuries.
The method needs improvement to work accurately but it may soon be ready for trials on paralysed people with so-called "locked-in" syndrome, the researchers said.
People with the syndrome cannot speak and usually communicate by blinking or moving a hand slightly.
