What about 5500? 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.
