telephone conference November 17th, in conjunction with the announcement that he and his colleagues have succeeded in generating bioengineer vocal-phoned that were capable of producing sound. A first step toward implant one day. Their study is on the journal Science.
The research team started with vocal tissues from and from four patients who have their vocal boxes removed.
They took from those tissues sample and successfully grew them on a three-dimensional to produce new vocal .
So how do the lab-grown vocal actually sound?
We did some testing where put on a fake in hot warm , just like the body into the vibration. But they vibrate and generate sounds just into the atmosphere. And so the sound is quite different than what is coming out from my mouth in present. What vocal track sounds a zoo little bit like a or kind of a robot sendings, like Yeeee. But that’s how it should sound in this context.
