LENA Pro, our software tool that started it all.


Measurable outcomes delivered through a scalable, ready-to-launch community program.

Interventions with large populations often hit two roadblocks: excessive complexity and inconsistent implementation. LENA Start avoids these traps by focusing on a single goal—improving talk between parents and children.

Unique data insights coupled with strengths-based coaching.

LENA Grow is a professional development program for early childhood teachers that uses regular feedback from LENA technology to improve the talk environment in the classroom. Teachers meet weekly with a coach one-on-one or in group sessions. The coaching sessions provide time to review the data on the interactive talk environment in each classroom, and use the data to set goals to talk more.

LENA Grow has seen rapid expansion since its 2016 pilot in partnership with the Early Learning Coalition of Escambia County, Florida. It is now part of professional development initiatives serving more than 400 classrooms at 113 centers across 14 states.

Helping parents and home visitors collaborate to improve children’s language environments.

Developed over two years of piloting with the Providence Talks home-visitation program, LENA Home is an add-on for your existing parent coaching curriculum. Home visitors using LENA technology to measure language gain objective insights on home talk that can be used to inform and motivate parents and track progress toward increasing interaction. LENA Home is ideal for coaching and home visitation programs that would like to supplement their curriculum with objective feedback from LENA technology.

Productivity is increased through:

  • Clear reports that provide insights on how much adults spoke, back and forth exchanges between parents and child, and tv and electronic sound throughout the day. 
  • Feedback designed to show progress over time.
  • Scheduling and text reminders that simplify logistics and ease the burden on home visitors. 
  • Implementation support and one year of technical assistance.
  • Two validated measures of child language behavior.

    Reliable, detailed language environment data with convenient access and security.

    LENA SP provides a complete picture of a child’s audio environment for researchers, speech-language pathologists, professionals working with children with hearing loss, and others who need detailed, scientifically reliable speech-language measurements of children 2 months to 48 months old.

    The use of cutting-edge LENA recording devices has broadened our data collection options and allowed us to work as a team to both examine language experiences and utilize data to provide feedback to teachers upon which to build their strategies for infants and toddlers with developmental delays.

    Our original software tool that started it all.

    The LENA Pro software automatically analyzes and segments the audio data, providing four primary reports plus a composite report that can be viewed in monthly, daily, hourly, and five-minute time-frames. Export features and a sophisticated data mining tool allow you to customize analysis with ease, down to the millisecond.
