Can Smartphones be a cost-effective alternative to LENA for Early Childhood Language Intervention?

Satwik Dutta, Jacob C. Reyna, Jay F. Buzhardt, Dwight Irvin, John H.L. Hansen

Although non-profit commercial products such as LENA can provide valuable feedback to parents and early childhood educators about their children’s or student’s daily communication interactions, their cost and technology requirements put them out of reach of many families who could benefit. Over the last two decades, smartphones have become commonly used in most households irrespective of their socio-economic background. In this study, conducted during the COVID-19 pandemic, we aim to compare audio collected on LENA recorders versus smartphones available to families in an unsupervised data collection protocol. Approximately 10 hours of audio evaluated in this study was collected by three families in their homes during parent-child science book reading activities with their children. We report comparisons and found similar performance between the two audio capture devices based on their speech signal-to-noise ratio (NIST STNR) and word-error-rates calculated using automatic speech recognition (ASR) engines. Finally, we discuss implications of this study for expanding this technology to more diverse populations, limitations and future directions.
