What does "LENA" mean?

LENA's name comes from Language ENvironment Analysis, the technology at the core of our early language programs. LENA technology is the industry standard for measuring talk with children, which is a critical factor in early brain development. 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.
