That is a crazy sound the robot voice makes between врач and говорит!
Врач ЖЖЖЖЖ говорит
Yes. The audio is bad. It's not like Russian doesn't have its fair share of Ж-Ш sounds as it is, don't make it sound like Polish ;-)
So how would you differentiate between saying that the doctors says that 'he himself is healthy' vs saying, 'that guy over there is healthy?'
And how would you tell the difference in English? Context is your friend...
Could we use something like себе in this sentence to mean that doctor is talking about himself?
