How does LENA’s “talk pedometer” technology work?


LENA uses a small wearable device — often referred to as a “talk pedometer” — combined with cloud-based software to deliver detailed feedback that helps adults make proven, sustainable increases in interactive talk with children.

Research shows that there’s significant variability in how much adults talk with children and tells us that those who talk the least tend to overestimate how much they talk the most. Adult talk levels vary significantly during the course of the day and from week to week. That’s where LENA comes in — our language-measurement technology is an objective tool to help parents and teachers understand, measure, and increase conversations with children.
