In this 2006 photo released by the LENA Research Foundation, Evelyn Paul demonstrates inserting a device into the clothing of her daughter, Carolyn Paul, which can track the number of words and conversations a child hears during the course of a day. The city of Providence, R.I., plans to distribute the devices to low-income children as part of a plan to improve their language skills, to be funded in part after the city won a $5 million contest created by New York Mayor Michael Bloomberg.
