The researchers first surgically implanted a high-density electrode array over BRAVO1s speech motor cortex.
The implant was then connected to a computer via a port in his head.
This vocabulary could collectively generate more than 1,000 sentences.
Between them, they could collectively generate more than 1,000 sentences.
BRAVO1 was then askedto say different short sentences composed of the 50 words.
The words were then decoded from his brain activity onto a screen.
Next, the team tried a question-and-answer test.
When they asked him, How are you today?
his response, I am very good, appeared on the screen.
A lot of previous research in this field used spelling-based approaches to typing out letters one-by-one.
The system is, however, still prone to errors.
The team is now trying to improve their systems vocabulary and rate of speech.
