I can tell tone of voice, but pretty much only when I'm not processing language. My brain tends to favor tone over language, but when I do do language, it switches to language over tone. It's both at once that I can't do, and I've heard this from many other people including Temple Grandin. (And Donna Williams too... like me, her brain is more about tone than words, but she can do words with great effort.)
