'Exhilarating' implant turns thoughts to speech. The headline about this neural prosthetic is a bit misleading. It's proving to be - as anyone with knowledge of spcyhology would expect - challenging to turn thoughts into speech. The headline suggests that the person thinks of saying "What a nice day today" and an external speaker produces those sounds. What actually happens is that an implant picks up motor instructions in the brain to the articulatory apparatus (jaw, tongue, and larynx), and an external system then synthesises the sounds. As you can hear from the sample, it's currently far from perfect, but this type of technology usually improves quickly.
