I’m fascinated and blown away by this ability. It really shows how good you are in a language to be able to process so quickly, but I also think it’s a separate talent to function fluently in a foreign language, even do interpretation, and to process like this in simultaneous interpretation.
This is an example of Chinese-English simultaneous interpretation, without subtitles or script, but relying only on listening ability. There are naturally some mistakes and not everything is interpreted, but it still blows my mind, as I’m certainly not able to do this!
I’ve done interpretation and translation professionally, both of which allow some processing time, and so know how difficult that can be. Simultaneous interpretation just amazes me.
The only thing more mind blowing would be simultaneous interpretation between two languages foreign to the interpreter.
