ADEX


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.
