arXiv:2606.01045v1 Announce Type: new Abstract: Recent studies suggest that child-directed speech is not conducive to language learning in BabyLMs. However, current evaluations focus predominantly on comprehension and not production, which is central to usage-based theories of language acquisition which argue how CDS facilitates early language use through constructional ''frames'' (frequent lexical patterns with open slots). We introduce a novel generation-based evaluation inspired by such theories in form of a frame-completion task, and compare Llama models trained with CDS, the BabyLM corpus
This research emerges as the field of AI, particularly large language models, grapples with understanding human language acquisition and seeking more efficient training methodologies.
It provides critical insights into the differential effects of training data on AI model capabilities, specifically separating comprehension from production, which refines our understanding of language model development.
Our understanding of 'child-directed speech' and its role in AI language model training is refined, highlighting its facilitation of generative capabilities over passive comprehension.
- · AI researchers focusing on generative models
- · Developers of AI systems requiring nuanced language production
- · Educational technology platforms incorporating AI for language learning
- · AI models trained exclusively for comprehension with child-directed speech
- · Theories overstating child-directed speech's universal benefits for all language
AI model training strategies will be re-evaluated to better distinguish between comprehension and production goals when selecting datasets.
New benchmarks and evaluation metrics for generative AI capabilities will likely emerge, moving beyond purely comprehension-based tests.
This could lead to specialized AI models, with some optimized for understanding and others for generating language, potentially leading to more targeted and efficient AI applications.
