It ends at the point of not being annoying to the other passengers.
Singing loudly = annoying.
Talking on your phone loudly = annoying.
Having a shouting match with the person next to you = annoying.
Speaking in a normal conversation voice in your own native language = not annoying.

Do you think it’s not possible for someone to be annoying even when they’re speaking your language in a normal conversation voice?

I might add that we don’t know if the people in this situation were speaking in a normal conversation voice, but then there couldn’t possibly be anything we wouldn’t know from this news blurb.
