The Science Behind LENA Technology

LENA technology has been proven in use worldwide for more than a decade, by researchers, clinicians, and interventionists. Its language statistics were validated in a large-scale study that established norms for words, turns, and child vocalizations. Every aspect of the technology has been extensively tested and calibrated in use through thousands of recordings in multiple languages, and widely documented in published research.

How does LENA protect privacy and security?

In LENA Start, LENA Grow, and LENA Home, audio recordings are automatically deleted immediately after processing into data (number of words and turns, etc.). The recorder has no playback capability and the system doesn’t recognize the meanings of words, so no one can ever tell what the users talked about.

LENA SP and LENA Pro are the only two versions of LENA that allow the option to retain audio. Each group provides its parents with its own consent form, and parents have the option to participate or not.

LENA takes security seriously. We have built and implemented a multitude of technologies and processes to protect your data – and we stand behind them. We are proud to be Type II SOC 2 compliant, which means that every year an outside group audits LENA to confirm that we have appropriate data and privacy protections in place and are using them correctly. Learn more about LENA’s Type II SOC 2 compliance.
