Researchers at Pohang University of Science & Technology developed a skin-attachable vibration sensor for accurate voice recognition. The sensor can quantify voice pressure and recognize speech without ambient noise or sound distortion.
A new study by Jody E. Kreiman investigates how people perceive voice quality and defines a 'normal' voice. The results show that listeners are consistent in their judgments of abnormal voices but disagree on what constitutes a 'normal' voice, highlighting the complexity of voice perception.
The American Academy of Otolaryngology has released an updated guideline for treating hoarseness, recommending earlier evaluation by an otolaryngologist and discouraging the use of unnecessary medications. The guidelines aim to reduce variation in care and improve patient outcomes.
Researchers found that skilled voice impersonators can successfully deceive automatic speaker recognition systems by mimicking specific speakers. The study highlights the vulnerability of these systems to human-induced voice modifications, particularly those produced through imitation and disguise.
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.
Scientists at UCLA's Voice Center for Medicine and the Arts studied Hillary Clinton, Bernie Sanders, Donald Trump, and Carly Fiorina's speech patterns across various settings. They discovered that despite differing messages, the politicians employed similar voice modulation strategies to convey charisma.
Researchers developed a high-speed MRI technique to visualize laryngeal movement in detail. This breakthrough enables studies on the aging voice and potential interventions like vocal training.
Researchers discovered that male radio performers have faster and more forceful vocal fold closures than non-broadcasters. This may be due to better control of vocal tension while speaking. The study used high-speed videoendoscopy to examine the vocal folds of healthy performers.
The study found that voices similar to one's own convey a sense of community and social belongingness. Key gender differences were identified, with females preferring breathier voices and males preferring shorter average word length. Regional dialects also played a significant role in voice preferences.
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.
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.
Researchers have developed improved artificial voice devices that can produce age-appropriate voices for children and women with vocal cord problems. The new technology enhances speech signal analysis by tackling the challenge of identifying glottal excitation signals in higher-pitched voices.
Researchers have found that a white whale named NOC can imitate human speech by modifying its vocal mechanics. The study's findings suggest that NOC had motivation for contact and made an effort to produce speech-like sounds.
Scientists have developed a new material to restore lost flexibility in human vocal cords, which can help alleviate voice loss due to aging, disease, or medical procedures. The material, called polyethylene glycol 30 (PEG30), is flexible and can vibrate like human vocal cords.
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.

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.
Researchers at the University of Washington have developed Vocal Joystick, a device that uses voice commands to control cursor movement and other screen interactions. The technology has shown promising results in early tests, allowing experienced users to achieve similar levels of control as those using traditional interfaces.
