Pitch range produced by vocal cords

Researchers at the University of Utah have discovered that vocal cords can be stretched and stiffened to predict an animal's pitch range, revealing evolutionary roots of voice. The study suggests that singers can increase their ranges by stretching their vocal cords or engaging in exercises that affect fiber spacing and cord stiffness.

Beatboxing poses little risk of injury to voice

Researchers at the University of Illinois Chicago have found that beatboxers use the whole vocal tract to produce a range of sounds, spreading the energy among several structures and minimizing wear on any single part. This technique may be protective of the vocal folds and could help singers relieve stress on their vocal cords.

An elephant that speaks Korean

Researchers found that Koshik can mimic five Korean words: 'annyong' (hello), 'anja' (sit down), 'aniya' (no), 'nuo' (lie down), and 'choah' (good). The elephant's language skills may provide insights into the biology of complex vocal learning, crucial for human speech and music.

Born to roar

Researchers found that the structure of lion and tiger vocal folds, including fat and viscoelastic properties, determines the low-frequency roars. The study challenges previous assumptions about the causes of loud roaring in these big cats.

Novel surgery removes rare tumor, rebuilds trachea

A team of surgeons at Henry Ford Hospital has successfully removed a rare malignant immature teratoma from an adult's trachea and rebuilt the airway using tissue and bone from the patient's arm. The patient is now able to speak and swallow normally, with only a temporary tracheostomy tube used for breathing assistance.

A sing-song way to a cure for speech disorder

Speech-language pathology researchers at the University of Missouri are studying Hindustani and classical singing styles to develop a treatment for laryngeal tremors. By understanding the physiology behind voluntary and involuntary pitch fluctuation, they aim to find a cure for this vocal disorder associated with neurological disorders.

Kent State researchers and Barack Obama's 'rope-a-dope' style

Researchers Drs. Will Kalkhoff and Stanford W. Gregory Jr. studied nonverbal vocal communication in presidential debates, finding that subtle cues can predict dominance. They noted a 'rope-a-dope' debating style similar to boxing legend Muhammed Ali's technique, where candidates conserve energy until the end of debates.
