arXiv:2606.01134v1 Announce Type: cross Abstract: Automatically distinguishing child-directed speech from adult-directed speech in long-form recordings is key to scalable analyses of children's language environments. Existing approaches process utterances in isolation and have been evaluated primarily on English. We address these gaps along three dimensions. First, we fine-tune and evaluate six-self supervised models on a multilingual dataset of 182 children, showing that in-domain pre-training on child-centered recordings substantially outperforms models trained on adult speech. Second, we de
The proliferation of long-form audio data combined with advancements in self-supervised learning for speech processing makes this research timely, enabling more accessible and scalable language development research.
This development allows for more accurate and scalable analysis of early childhood language environments, critical for understanding developmental trajectories and enabling early intervention programs on a global scale.
The ability to automatically and accurately distinguish between child-directed and adult-directed speech in diverse linguistic contexts moves from isolated utterance analysis to continuous, naturalistic data streams.

More efficient and comprehensive data collection for child language acquisition studies becomes possible.
This improved data could lead to new insights into language development across diverse cultures and socioeconomic backgrounds, potentially informing public health and educational policy.
The technology might enable personalized interactive learning tools that adapt to a child's specific language environment and developmental stage.
