yelps

Yelps are short, sharp vocalizations characterized by a high pitch, produced by humans and animals in response to sudden pain, surprise, fear, or intense emotion. The word is onomatopoeic, imitating the sound; in English it can function as a noun (a yelp) or a verb (to yelp).

In animals, yelps are common in domestic dogs and other canids, as well as in some small mammals. They often signal distress, pain, or alarm, but can also occur during excited play. Yelps are typically brief and perceptually high-frequency, sometimes emitted in rapid bursts. They are distinguished from longer vocalizations such as barks, howls, or whines by their short duration and urgent tone. Researchers and animal welfare workers monitor yelps as indicators of discomfort or fear in animals.

In humans, yelps occur most often in infants and young children as a reflexive or communicative response to sudden discomfort or surprise. Adults may yelp in moments of sharp pain or surprise, though the sound is less common in everyday polite speech. As a linguistic or descriptive term, yelp conveys a quick, involuntary vocalization rather than a deliberate utterance.
