LENA SP provides a richly detailed picture of a child's language environment, for researchers, speech-language pathologists, and others who need detailed, scientifically reliable speech-language measurements of children 2 months to 48 months old.

LENA recording technology captures a full day of language at a time, while the software system automatically analyzes and segments audio data. Flexible uploading and processing via a secure cloud-based service simplifies logistics of working with multiple children and sites and provides secure access from anywhere, 24/7. Data include validated percentiles for adult words, conversational turns (serve-and-return interactions), and child vocalizations. Audio recording may be retained at user option (in this version of LENA only), so professionals working under confidentiality requirements or informed consent agreements can perform more granular analysis where necessary.

LENA SP allows users to access data on many aspects of a child’s language environment, including the number of conversational turns and adult words, how much of the day the child was exposed to talk, and more. With LENA SP you can:

• Access raw data and, at user option, high-quality audio files underlying the reports to perform analyses including transcription, language samples, spectral analysis, etc.
• Manage program data through LENA Online for scalability, access, and outcome-tracking.
• Access the Developmental Snapshot assessment, a validated 52-item caregiver-completed questionnaire that measures a child’s expressive and receptive language development.
• View AVA (Automatic Vocalization Assessment) scores, a unique measure of the similarity of a child’s patterns of vocalizing to those of a reference sample of typically developing children around the same age. Reported as an age standardized score to facilitate tracking over time.

Funding through the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR), and the Disability Research and Dissemination Center (DRDC) has enabled collaboration between the University of Colorado-Boulder and LENA to support pilot testing, refinement, and enhancement of LENA SP. Other current partners incorporating LENA SP into their interventions and research studies include:
