Exciting stuff:

Note that using this BMI interface he can only produce 3 vowel sounds currently. We aren't talking about full speech here or anything close to it. However given how this works it's impressive and further research could lead to some amazing things:
"
Although the current study focused only on producing a small set of vowels, the researchers think that consonant sounds could be achieved with improvements to the system. While this study used a single three-wire electrode, the use of additional electrodes at multiple recording sites, as well as improved decoding techniques, could lead to rapid, accurate control of a speech synthesizer that could generate a wide range of sounds.
Our immediate plans involve the implementation of a new synthesizer that can produce consonants as well as vowels but remains simple enough for a BMI user to control, Guenther said. We are also working on hardware that will greatly increase the number of neurons that are recorded. We expect to tap into at least 10 times as many neurons in the next implant recipient, which should lead to a dramatic improvement in performance.
