So they knew his brain's speech centers were still functioning. They just needed a way to connect those speech centers to a speech synthesizer - an artificial mouth if you will. Researchers implanted a special kind of electrode in his brain, one that's "impregnated with neurotrophic factors" that encourage brain neurons to grow into and around the electrode. Essentially this electrode forms a very strong connection with brain neurons, which results in a strong signal that reliably comes from the same part of the patient's brain over time.

Over a period of weeks, Guenther and his team worked to decode the signals coming from the man's brain. Eventually, he was able "to produce three vowel sounds with good accuracy," said Guenther. The man produces these sounds as quickly as he would normal speech, and Guenther added, "The long-term goal within five years is to have him use the speech brain–computer interface to produce words directly."

Despite his problems, it is still a wonderful story. How good would they feel giving him this gift.
