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.
Should bioengineered vocal    someday be implanted into a human patient. The sound would be far different due to the other structure problems more like what you’ve just been listening to.
