A recent article in Nature highlights a discovery that pushes the boundaries of our imaginations and challenges some of the very attributes that make us human. The piece details how artificial intelligence is creating speech by interpreting brain signals (and even offers an audio recording for a chance to hear it for yourself). It’s a key advancement for people who can’t speak because it provides a direct technologically-enabled path from thought to speech.

The implications of this discovery go beyond the recreation of speech: A.I. was used to decode brain waves and then reassemble neural impulses. While the focus of this study was on the mechanistic components of speech, such as direct muscle movement, it still acquired information from the early stages of thought development to construct words that were identifiable about 70% of the time. In other words, A.I. actually translated the code that makes up pre-speech. READ MORE ON: FORTUNE
