StoryCorps and the human voice

From Wikipedia: StoryCorps interviews usually take place between two people who know and care about each other. They can be friends, family, or mere acquaintances. A trained StoryCorps facilitator guides participants through the interview process. At the end of each 40-minute recording session, participants receive a complimentary CD of their interview and are requested to make a $50 donation to offset the recording costs. With participant permission, a second copy of each interview is archived at the American Folklife Center at the Library of Congress for future generations to hear. Segments of select interviews may air nationally on NPR’s Morning Edition. These interviews can also be heard on the StoryCorps website.
