LENA Pro was specifically designed for researchers, speech-language pathologists (SLPs), audiologists, and pediatricians. LENA allows you to easily collect, process, and analyze language environment and development data for children ages 2 months to 48 months.
The LENA Advanced Data Extraction (ADEX) tool extends the scope of LENA-based research beyond the basic LENA language indices (e.g., Adult Word Count, Conversational Turns, Key Child Vocalizations, AVA). Using ADEX, researchers can examine word count data separately for male and female adults, find the average and peak energy levels of each vocalization activity block and retrieve duration data for non-key child vocalizations, overlapping speech, TV, noise, and silence.
