They claim that it has an accuracy rate of 90 per cent or more and say that it works by interpreting consonants and vowels in our brains.

The researchers believe that the machine could one day help patients who suffer from conditions that don't allow them to speak or move. 

The machine registers and analyses the combination of vowels and consonants that we use when constructing a sentence in our brains. 

It interprets these sentences based on neural signals and can translate them into text in real time.

In fact, scientists claim that the machine can use words that it hasn't even heard before.   

Study leader David Moses told the Sun: 'No published work has demonstrated real-time classi?cation of sentences from neural signals.

'Given the performance exhibited by [the machine] in this work and its capacity for expansion, we are con?dent in its ability to serve as a platform for the proposed speech prosthetic device.'
