The Highly Accessible LENA Natural Language Corpus and Database*

Our natural language corpus is massive and continues to grow. Qualified researchers can quickly access nearly 6,000 recording sessions with demographic information. That’s over 81,000 hours of naturalistic, in-home recordings – unique and valuable information gathered from nearly 600 families. The majority of our participant children have been evaluated by certified speech-language pathologists on multiple occasions using language and cognitive measures such as the PLS-4, REEL-3, CDI, PPVT, and CAT/CLAMS. Furthermore, we can make our IRB-approved Informed Consent Forms available, helping to accelerate your IRB approval processes.

Our data from children ages 2 months to 76 months contain roughly:

81,385 hours from 5,955 recordings contributed by 562 participating families
5,930 hours from 365 recordings from 53 families of children with a diagnosed language delay
2,290 hours from 145 recordings from 21 Spanish-speaking families
300 transcribed hours from 215 children
6,340 hours from 390 recordings contributed by 79 families of children with diagnosed Autism
