Speech delay is also known as Alaila, which refers to a deferring in the advancement or use of the instruments that produce speech. Speech – unmistakably unique from language – is the actual method of sound production. The mechanism makes use of such organs and structures as the lungs, vocal cords, mouth, tongue, teeth, etc. Language delay, on the other hand, indicates a delay in the development or the inability to adopt knowledge of the language.
Owing to the fact that language and speech are two separate stages, their developmental delays cannot be interlinked, contrary to popular belief.
