What is the difference between speech and language?

Speech is defined as spoken language. It refers to “how” we produce sounds and words and involves articulation, voice, and fluency.

Language is a socially shared code that represents concepts with arbitrary symbols, which provides a set of rules as to how those symbols can be combined and used. It refers to the entire system of expressing and receiving information in a way that’s meaningful. It involves our understanding of others (receptive) and our meaningful expression of thoughts and feelings (expressive).
