Speech sound development (sometimes referred to as Articulation) refers to the developmental stages at which children typically acquire and master specific sounds in their speech. These milestones provide a framework for understanding the progression of speech acquisition from infancy through early childhood. Initially, infants produce simple sounds such as cooing and babbling, laying the foundation for speech development.

Early intervention for language development is paramount as it lays the foundation for lifelong communication skills and cognitive abilities. During the critical early years, children's brains are highly receptive to language input, and timely interventions can significantly impact their language development. Early identification and intervention for language delays or disorders enable Speech-Language Pathologists to implement targeted strategies to support a child's communication needs.
