NOTE: I am not asking whether "audience" is a singular or plural word.
I am writing critical analyses of essays written by influential people. So, a sentence in my analysis could be: (in an essay protesting against governmental policies)
The reader at this point feels guilty for supporting his government.
Now, what if I am critically analysing a speech? Surely, a speech has an audience and not just one reader. But, I still wish to refer to just one person, the same way as I did in the above sentence. One possible approach in my mind is:
Every person in the audience at this point feels guilty for supporting his government.
But, it's a bit verbose imo. I hope there might be more elgant or entirely different expressions.
