The story in our family has always been that my paternal grandfather worked as a telephone technician at the turn of the century, and called a particular number from the top of a telephone to check the line.

The woman who would turn out to be my grandmother picked up the line...

The fact that he was my grandfather, and she my grandmother kinda gives away the ending of the story, doesn't it? ;-)

Though I will say this: he may have first been smitten by the sound of her voice, but there was a period of daily letters back and forth between them for a long time (a year? I'll have to check), before they got married.

So the spark can definitely be there from the sound of the voice alone, even without pheromones... But for "smitten" to turn to "love" took a good deal of work.

Though now that I think of it, sound, like smell, has a direct connection to the emotion centers of our brain -- particularly tone of voice: the coo of a mother's lullaby, a cry of alarm, a growl of anger, etc.

That's the long answer.

The short answer is: "Yes."
