I can't really flag the report, because it gets marked as accepted. The only other option I have is "something else was wrong", but I can't specify what. Pressing that instead of writing a message here seems less effective. Doing both seems redundant. But I can do both; would you like me to do both?
The vocalisation (male) on this question is wrong. It sounds like he says "... 'oHej ...", not "... 'oHbej ...". I think I may have reported this one before (though it may have been a similar error on another question). But when 'flagging', there's no indication that I've done this, so I'm commenting instead as a note to myself that I've reported this one. Earlier comments in this thread about commenting vs flagging refers.
We appreciate your coming here to let us know what your issue with the sentence is. We often can't hear it ourselves, because, for example 'oH'ej is not a meaningful utterance, so our brains would fill in the missing sound, as they would in a noisy room. In this case I hear a b sound (remember it's not supposed to be a forceful sound), and if there had been an audio flag I would have guessed it to be because I don't hear a puff of air on the p in pong.
There was not an audio flag on the sentence: Duolingo doesn't pass those messages up from all platforms. I'll let the loDpu' decide what they think of this one.
