yelp

This term captures a sudden, piercing sound that is more abrupt than a scream and higher in pitch than a shout. It is most frequently associated with canine behavior, evoking the image of a dog reacting to a sudden stimulus, though it applies equally to humans in moments of acute shock or sharp physical pain. In social contexts, the word carries a connotation of vulnerability or involuntary reaction. While a shout is often intentional and controlled, a yelp is typically an instinctive burst of sound, suggesting a loss of composure or an immediate, reflexive response to an external trigger.
