When you look at a still picture of someone whom you've never heard speak, do you already get a sense of what their voice will sound like in your mind? For instance, when you see a picture of someone on the internet, and you read an E-mail from that person. It frequently happens to me. Some of the time, when I eventually hear their actual voice, it sounds similar to my imagined voice, other times, it's totally different! The vocal sounds my mind places on someone is frequently made from a person of similar apperance that I have met in the past.
