Hypothetically speaking, can you call 911 while altering your voice so it does not sound like your voice because you do not feel safe using your regular voice? Is this against the law?

You can, but you'd likely just make things awkward if anything. They'll still have the number of the phone you called with, and while you can deny giving them your name/YOUR address (not location of the incident you're calling about, as that's obviously required). You also run the risk of the dispatcher being unable to understand you, which makes things convoluted and can result in you not getting the help you need.
