> Makes me wonder if you would outperform seeing people in recognizing audio cues, like the tone of the voice to interpret emotion?

By necessity I have to be tuned in to the sounds in my physical environment, to pick up any clues which give me an edge when navigating that space. I'd say it was fairly likely that I do the same when communicating with other people - one of the things that attracts me to people is the sound and tone of their voice. I find it difficult to enjoy acting performances, conference talks, etc when something is off about a person's vocal delivery, however small. Although that probably also has to do with the fact that for much of the day I'm listening to a rapidly-speaking text-to-speech engine.
