Speech delay, also known as alalia, refers to a delay in the development or use of the mechanisms that produce speech. Speech, as distinct from language, refers to the actual process of making sounds, using such organs and structures as the lungs, vocal cords, mouth, tongue, teeth, etc. Language delay refers to a delay in the development or use of the knowledge of language.
Because language and speech are two independent stages, they may be individually delayed. For example, a child may be delayed in speech (i.e., unable to produce intelligible speech sounds), but not delayed in language. In this case, the child would be attempting to produce an age appropriate amount of language, but that language would be difficult or impossible to understand. Conversely, since a child with a language delay typically has not yet had the opportunity to produce speech sounds, it is likely to have a delay in speech as well.

Famous quotes containing the words speech and/or delay:
“The less sophisticated of my forbears avoided foreigners at all costs, for the very good reason that, in their circles, speaking in tongues was commonly a prelude to snake handling. The more tolerant among us regarded foreign languages as a kind of speech impediment that could be overcome by willpower.”
—Barbara Ehrenreich (b. 1941)
“Hatred and vengeance, my eternal portion,
Scarce can endure delay of execution:—
Wait, with impatient readiness, to seize my
Soul in a moment.”
—William Cowper (1731–1800)
