The condition exists, the only thing made up is that cheesy idea that you will meet someone special whose face you will remember, there are different levels of prosopagnosia and if you have it that bad, that is all.
No, you can't recognise people just by their voice, maybe after some time of focusing on it with that intention. My condition is not as bad as hers but I have to make a mental list of things that distinguishes the person from the others, which is not too practical because they are common or can change. At the start is just hair color, beard, glasses, skin color, fat/thin and "does he have glasses?", scars are blessing. The only non measurable thing I've ever use are things like "Something in his eyes makes it seem like he is always sad" (which isn't always true..., so no reliable either).
The measure she uses at some point of the movie is funny but makes sense. After some months I can actually see the differences and not just memorize them, but I'm a lucky one (and don't dare to change your haircut). Until then I have to count the stripes of the zebra.
