I'm a "voice" person, I often have trouble recognizing people, but as soon as they speak I know them instantly...movies/tv and in real life.
Jessica Hecht comes to mind when I read a Soz post, they do look somewhat similar, {from the one photo I've seen} but its mainly the voice. I can't find the exact picture I want but this one will do.

She has this great voice with some...well, unusual tones in them...not that unusual is bad...think unique. She was on two tv shows that I know of...."The Single Guy" and "Friends".
I saw her last night in the movie "Stay"...very small part, and she looked quite different, but as always...within a few syllables, I knew it was her.
