Nerve‐Induced Rabbit Phonation: Temporal Phonation Stability
Otolaryngology–Head and Neck Surgery, 2008ProblemIn‐vivo phonation using animals with layered structure similarities and phonation characteristics akin to humans are needed for the study of vocal fold reparative processes. The authors’ previous studies have demonstrated the feasibility of eliciting vocalization in a flow‐controlled in‐vivo rabbit preparation.

The Journal of the Acoustical Society of America, 1973
Often when vowel loudness is measured, only SPL, duration, fundamental frequency, and formant frequencies are considered as causes of loudness. In the present study, differences in loudness were measured which apparently are a function of the mode of laryngeal vibration. Stimuli were constructed by having speakers produce a series of vowels at a single

Disorders of phonation in children
Pediatric Clinics of North America, 2003Vocal disturbances in children are surprisingly common. Typical pathologic conditions differ, however, from those that are seen commonly in adults. Disturbances in the vibratory characteristic of the vocal folds cause dysphonia. The most common causes for dysphonia are infectious, anatomic, congenital, inflammatory, neoplastic, neurologic, or ...

Vocal emotions are signaled by specific patterns of prosodic parameters, most notably pitch, phone duration, intensity, and phonation type. Phonation type was so far the least accessible parameter in emotion research, because it was difficult to extract ...

Swallowing, phonation, and articulation
2016The final common pathway related to swallowing (deglutition), phonation (vocalization), and articulation involves the ninth cranial nerve (glossopharyngeal nerve), the 10th cranial nerve (vagus nerve), and the 12th cranial nerve (hypoglossal nerve). This chapter explains the symptoms and signs caused by impairment of this system.

Phonation threshold pressure measurements during phonation by airflow interruption
The Laryngoscope, 1999AbstractObjective/Hypothesis: Most methods to measure phonation threshold pressure (PTP) are clinically impractical because they are invasive. This report concerns an airflow interruption system developed to allow noninvasive estimation of (PTP) at different levels of vocal intensity.

Mechanical stress in phonation
Journal of Voice, 1994Mechanical stress is always encountered in phonation. This includes tensile stress, shear stress, impact stress during collision, maximum active contractile stress in laryngeal muscles, inertial stress, and aerodynamic stress (pressure). Order of magnitude calculations reveal that tensile stress can reach the greatest value (near 1.0 MPa), contractile ...

Many studies have been conducted on acoustic differences between female and male speech. However, they have generally been led on speakers of only one language, and have focused on a single acoustic parameter. The present study is an acoustic analysis of

The elaboration of phonatory behaviour observable in the processes of human communication demands levels of physiological complexity which generally exceed those encountered in any other species. This represents arguably the most advanced sensorimotor system to be found in the human organism.

An analysis of the mechanics of phonation
Journal of Applied Physiology, 1965The mechanical work done by the chest in phonation has been measured together with the sound intensity level. The regulation of the sound intensity is done by regulating the intrapulmonary pressure. This is achieved at high intensity levels through the activity of the respiratory muscles that, together with the elastic recoil of the chest, sustain the
