People with paralysing conditions such as motor-neuron disease often rely on technology to help them to speak. (BJ Warnick/Alamy))

Brain signals translated into speech In an effort to provide a voice for people who can’t speak, neuroscientists have designed a device that can transform brain signals into speech using artificial intelligence. The technology can synthesize whole sentences that are mostly intelligible although it isn’t yet accurate enough to use outside the lab. Researchers trained the system with five volunteers who read hundreds of sentences aloud while their brain activity was recorded by electrodes.
