I have my own experience i find quite interesting. I have been working as an interpreter for about a week and half translating from english to russian, and from russian to english for about 9-10 hours a day. We were accepting the russian speaking patients. I won't tell all the story and will go to some interesting results. After 3 days of hard work i've realized that from the distance of 2 meters i was hearing russian speech as english and vice versa. If i were blind it would be hard for me to distinguish between russians and brits. Yes, it's weird. It turned out that same effect was experienced by all the interpreters from our group. The second strange and i must say pleasant effect is in that there is no any thoughts in your head when you're not speaking or translating. Just silence, complete and absolute silence inside. Brain doesn't understand what language should be used for thoughts))) I guess. The next weird thing is that you have consciousness, you do all the things consciously but without any verbalized thoughts inside. It's like you have thoughts and you haven't simultaneously. WEIRD but very very pleasant))) So what is consciousness? What the thought is? Would like to make some studies of such states.

P.s
I'm fully agree with the scientists that did the mentioned in the article study that we need about 20 years of thorough research before going into public with some bold statements.
