"By measuring the brain signals in this area while Erik thinks about
speaking, we have been able to build a decoder that translates the
brain signals into the speech sounds Erik was thinking about," says
Guenther, an associate professor of cognitive and neural systems at
Boston University.
"The output of the decoder is used to drive a speech synthesizer,
which creates sound output."
Signals from the brain are received using three tiny wires. The
measurement of these electrical signals is very complex but eventually
may be able to decode Ramsey's thoughts and translate them into
recognizable speech.
