In cases of articulatory conflict, gestures involved in preserving phonemic distinctiveness are generally favored over gestures that do not. Here, an apparent exception to the phonemic distinctiveness preservation hypothesis is shown to in fact conform to it: in English, the larynx is lowered before voiced stops to maintain voicing distinctiveness, but the larynx is raised during high vowels, a...

Digital video filming of the thryroid prominence was used to measure larynx height in German vowels, with focus on contrasts involving front unrounded, front rounded and back rounded vowels. The study aimed to provide a foundation for interpreting the acoustic consequences of articulatory manoeuvres not only at the larynx but also elsewhere in the vocal tract. Results showed the expected patter...

Introduction: Isolated amyloidosis of the larynx is rare, being the single most common location in head and neck. Can be divided into diffuse and nodular, and the surgical treatment priority. Objective: To describe a case of isolated nodular amyloidosis of the larynx, with review of literature. Case report: A female patient, 23 years, presented with complaints of dysphonia and cervical cake for...

Optical coherence tomography OCT is an evolving noninvasive imaging modality and has been used to image the larynx during surgical endoscopy. The design of an OCT sampling device capable of capturing images of the human larynx during a typical office based laryngoscopy examination is discussed. Both patient’s and physician’s movements were addressed. In vivo OCT imaging of the human larynx is d...

OBJECTIVE This study aimed to: assess the mucosal alterations of the larynx and hypopharynx typical for mucopolysaccharidoses, in a standardised manner; compare the severity in different subtypes of mucopolysaccharidoses; and monitor the effect of an enzyme replacement therapy. METHODS A classification for mucosal alterations of the larynx and hypopharynx was developed and utilised in 55 pati...

Mammalian vocalizations exhibit large variations in their spectrotemporal features, although it is still largely unknown which result from intrinsic biomechanical properties of the larynx and which are under direct neuromuscular control. Here we show that mere changes in laryngeal air flow yield several non-linear effects on sound production, in an isolated larynx preparation from horseshoe bat...

Considering differences in laryngeal anatomy, degree of control, and range of voice qualities between animals and humans, investigations of the neuromuscular process of voice control are better conducted using a living human larynx in which parametric stimulation of individual laryngeal muscles is possible. Due to difficulties in access and monitoring of laryngeal muscle activities, such invest...

'Congenital laryngeal stridor' is merely a clinical description, and although perhaps 90 % of stridors in young babies are due to an exaggerated pattern of infantile larynx, which rectifies itself with increasing age, it is not safe to assume that this is the cause of the stridor. There are other conditions causing laryngeal stridor in young babies, sometimes from birth, which are graver than t...
