Speech refers to the physical ability to accurately and consistently produce sounds, known as articulation. For example, between the ages of 2 and 3 a child is expected to master their articulation of the following sounds: /p, b, m, n, t, d, k, g, h, w, f, y/, ‘ng’. An articulation disorder may occur when a child presents with difficulty producing speech sounds that are expected to be mastered by their chronological age.
In contrast, language refers to a child’s ability to express themselves with their use of vocabulary, use grammatical structures, create sentences of varying structural complexity, and social use of language. Additionally, language can also relate to their ability to comprehend language, follow conversation, and understand a variety of features.
