You likely don’t give a ton of thought to the sounds and patterns that make up the language you speak everyday. But the human voice is capable making of a tremendous variety of noises, and no language includes all of them.
About 20 percent of the world’s languages, for example, make use of a type of sound called an ejective consonant, in which an intense burst of air is released suddenly. (Listen to all the ejectives here.) English, however—along with most European languages—does not include this noise.
