This ASP has been validated in North American English and other languages in predominantly monolingual contexts but not in a multilingual context like India. Thus, the current study aims to validate the classification accuracy of the LENA algorithm specifically focusing on speaker recognition of adult segments (AdS) and child segments (ChS) in a sample of bi/multilingual families from India.</p><p><strong>Method: </strong>Thirty neurotypical children between 6 and 24 months (<i>M</i> = 12.89, <i>SD</i> = 4.95) were recruited.

Stimulus onset asynchrony (SOA) is used to investigate the interaction between the two modalities in speech perception.
