to create audible turbulence during speech. Supralaryngeal articulation remains the same as in normal speech. In normal speech, the vocal cords alternate between states of voice and voicelessness. In whispering, only the voicing segments change, so that the vocal cords alternate between whisper and voicelessness (though the acoustic difference between the two states is minimal). Because of this, implementing

Social role

Whispering is generally used quietly, to limit the hearing of speech to those closest to the speaker; for example, to convey

information without being overheard or to avoid disturbing others in a quiet place such as a library or place of worship. Loud whispering, known as a stage whisper, is generally used only for dramatic or emphatic purposes. Whispering can strain the vocal cords more than regular speech in some people, for whom speaking softly is recommended instead.


ASMR

In non-humans

The prevalence and function of low-amplitude signaling by non-humans are poorly characterized. As such, it is difficult to ascertain the existence of whispering in non-humans. This is made more difficult by the specific physiology of human whispering. By sufficiently relaxing the definition of whispering, it can be argued any number of non-human species demonstrate whisper-like behaviors. Often these behaviors function to increase fitness. If whispering is more broadly defined as the "production of short-range, low-amplitude acoustic signals," whispering is observed in myriad animals including non-human mammals, fish, and insects. If whispering is restricted to include only acoustic signals which are significantly different than those produced at high amplitude, whispering is still observed across biological taxa. An unlikely example is the
croaking gourami The croaking gourami (''Trichopsis vittata'') is a species of small freshwater labyrinth fish of the gourami family. They are native to still waters in Southeast Asia and are distributed worldwide via the aquarium trade. Croaking gouramis are ca ...
. Croaking gouramis produce a high-amplitude "croak" during agonistic disputes by beating specialized pectoral fins. Female gouramis additionally use these fins to produce an acoustically distinct, low-amplitude "purr" during copulation. If whispering is restricted to include only creatures possessing vocal folds (i.e., mammals and some reptiles), whispering has been observed in species including
cotton-top tamarin The cotton-top tamarin (''Saguinus oedipus'') is a small New World monkey weighing less than . This New World monkey can live up to 24 years, but most of them die by 13 years. One of the smallest primates, the cotton-top tamarin is easily reco ...
s and a variety of bats. In captive cotton-top tamarins, whisper-like behavior is speculated to enable troop communication while not alerting predators. Numerous species of bats (e.g.,

s) alter their echolocation calls to avoid detection by prey. Such a relaxed definition of whispering (i.e., production of short-range, low-amplitude acoustic signals which are significantly different than those produced at high amplitude) cannot be applied to humans without including vocalizations distinct from human whispering (e.g.,

). Further research is needed to ascertain the existence of whispering in non-humans as established in the larger article.
