Sonograms of female copulatory vocalizations of a human female (top), female baboon (middle), and female gibbon (bottom), [19] with time being plotted on the x-axis and the pitch being represented on the y-axis. In non-human primates, copulatory vocalizations begin towards the end of the copulatory act or even after copulation. [2]
The sound of each individual's voice is thought to be entirely unique [13] not only because of the actual shape and size of an individual's vocal cords but also due to the size and shape of the rest of that person's body, especially the vocal tract, and the manner in which the speech sounds are habitually formed and articulated. (It is this ...
Watts Hughes' work was not only demonstrated at a scientific meeting of the Royal Society, [3] her scientific paper in 1891 [1] led her to publish a 47-page book that extensively detailed how she made sound visible. The book was entitled The Eidophone Voice Figures: Geometrical and Natural Forms Produced by Vibrations of the Human Voice ...
Vocal learning is the ability to modify acoustic and syntactic sounds, acquire new sounds via imitation, and produce vocalizations. "Vocalizations" in this case refers only to sounds generated by the vocal organ (mammalian larynx or avian syrinx ) as opposed to by the lips, teeth, and tongue, which require substantially less motor control.

Use of creaky voice across general speech and in singing is termed "vocal fry". Some evidence exists of vocal fry becoming more common in the speech of young female speakers of American English in the early 21st century, [8] with researcher Ikuko Patricia Yuasa finding that college-age Americans perceived female creaky voice as "hesitant, nonaggressive, and informal but also educated, urban ...
The source–filter model represents speech as a combination of a sound source, such as the vocal cords, and a linear acoustic filter, the vocal tract.While only an approximation, the model is widely used in a number of applications such as speech synthesis and speech analysis because of its relative simplicity.
Toothed whale (odontocete) vocal anatomy. Most mammalian species produce sound by passing air from the lungs across the larynx, vibrating the vocal folds. [3] Sound then enters the supralaryngeal vocal tract, which can be adjusted to produce various changes in sound output, providing refinement of vocalizations. [3]
Due to the wide range of signal properties and media they propagate through, specialized equipment may be required instead of the usual microphone, such as a hydrophone (for underwater sounds), detectors of ultrasound (very high-frequency sounds) or infrasound (very low-frequency sounds), or a laser vibrometer (substrate-borne vibrational signals).
