If I set sample-rate to 11000 will ordinary speech be

11000 ought to be fine, as most speech-specific applications I've seen
default to 8000.
5500? Not sure. If your voice is low, it should still be fine, maybe a bit
muffled. But in the late '90s, when I was at a company looking at an early
VOIP PBX, we turned them down when the CEO and his wife tried to have a
conversation on their demo equipment and it bandpassed her very high,
squeaky voice right out of existence. So it's definitely possible to go too
low, though I can't imagine her voice was entirely over 2750Hz.
Should be pretty easy to test before doing any real recordings.
