Language development in children is influenced by context, social interaction, and cultural factors, emphasizing the importance of creating language-rich experiences aligned with their interests and stage of development.
Children's language acquisition differs from AI language models as they learn in social contexts with visual and contextual cues, suggesting the need for AI models to be trained on more enriched and contextualized data.

Child language development: Understanding how kids learn to speak
Child language development is a fascinating and complex process. It starts with infants babbling and gradually progresses to them speaking in a way that others can understand. The traditional idea that language development is solely based on imitation has evolved. Children not only imitate words and sounds, but they also learn grammar and how words fit together in sentences. Language learning is not solely dependent on cognition, but also on the ability to coordinate and move the mouth and other articulatory components. While there is variability in language development, comprehension and desire to communicate are good indicators of a child's progress. It is important to be aware of the milestones and seek professional help if a child consistently falls behind or shows limited communication skills.
The role of context, social interaction, and cultural influences in language development
Language development in children is enriched by context, social interaction, and cultural influences. Kids learn language in specific communicative and social contexts, such as conversations and play sessions. Communication with parents and caregivers, as well as exposure to different languages, shapes language learning. Research suggests that high-quality and interactive language-rich experiences, like reading books and engaging in conversations, have a positive impact on children's language development. It is important to create enjoyable and motivating language experiences for children, aligning with their interests and developmental stage.
Comparing child language learning to AI language models
Large language models, such as AI models like ChatGPT, have impressive language capabilities. However, these models require vast amounts of training data, often thousands of times more than what a child hears during their language acquisition process. One reason for this difference in sample efficiency may be the type of data these models receive. AI models are trained on decontextualized language data, such as vast unformatted text inputs from the internet. In contrast, children learn language in social contexts, accompanied by visual and other cues, within conventions and practices they understand. Exploring ways to provide AI models with more enriched and contextualized data, similar to what children experience, is an ongoing research area.
The variability and milestones in child language development
Child language development exhibits significant variability, with children reaching language milestones at different rates. While some children start combining words and communicating effectively by 18 to 24 months, others may take longer. It is essential to recognize that this variability is normal within the range of typically developing children. However, consistent difficulties understanding and producing language or limited communication gestures may indicate the need for further evaluation and intervention. Professionals can help determine if a child's language development is within the normal range or if there are concerns that require attention. Understanding comprehension and desire to communicate can provide reassurance about a child's language acquisition progress.
Through coos and cries, babbles and thbbbbts, babies are learning how to communicate from the earliest days of life. Language development is a magical opportunity to watch a child learn to engage with both you and the world. It also feels highly consequential, and for so many parents, it’s an incredibly stressful milestone. Watching your kid learn to talk is at once neat and frustrating and harrowing, all the more so when we realize that even the experts are often scratching their heads about how it all works.
Today on ParentData, Professor Michael Frank joins to explore the question of how children learn to speak. We talk about how language develops, the difference between receptive and expressive language, whether the pandemic had a significant impact, and which language is the hardest for kids to learn (spoiler alert: it’s Danish).
