Harðhljóð og linhljóð: Um aðröddunartíma í íslensku, sænsku og búlgörsku
… and the onset of voicing (vibrations in the vocal cords). This time is measured in ms and is negative for voiced stops and positive for unvoiced stops. VOT of +75ms and more is considered to indicated an aspirated stop. This thesis compares VOT of the fortis and lenis pairs of stop phonemes …

Detection of the uniqueness of a human voice: towards machine learning for improved data efficiency
… size and shape of the mouth, throat, nose, and vocal cords. Sound is produced by air passing from the lungs through the throat, vocal cords and then mouth. A voice makes different sounds based on the position of mouth and throat. It is the variation of these attributes that allows for …

Studies on the Changes Occurring in Speech and Masticatory Functions during Prosthetic Treatment // Изследвания върху промените, настъпващи в говорната и дъвкателната функции при протетично лечение
… was carried out to select patients without vocal cord pathology. Then, a retrospective study of the epidemiology of maxillary diastema was performed on patients from Northeastern Bulgaria. A speech therapy assessment was conducted on patients with single frontal maxillary defects before and …

Muscular control of vocal complexity in the túngara frog (Engystomops pustulosus)
… it through the larynx, inducing vibration of vocal cords. In male túngara frogs, a pair of fibrous masses is attached to the vocal cords and vibrates to produce the chuck. The mechanism that controls the optional production of the chucks was previously unknown. This study examined the muscles …

VocalCords: Exploring Tactile Interaction and Performance with the Singing Voice
… voice is surprisingly absent from traditional vocal performance technologies. This provides the motivation for VocalCords, which explores the design of a new digital music interface inviting tactile interaction and performance with the singing voice. The interface makes use of physical rubber …

Alternating Current Stimulation for Essential Tremor
… rhythmic shaking of the hands, head, trunk, vocal cords, or legs. While the pathophysiological mechanisms of essential tremor are not fully understood, research suggests the involvement of a complex network called the cerebello-thalamo-cortical network. This network includes the inferior …

Structure and social significance of vocalization by Anolis grahami grahami (Sauria: Iguanidae)
Even though the ability to produce vocalizations by the vibration of a membrane is widespread throughout the lizard suborder, only the sounds of geckos (Gekkonidae) have been closely studied. The purposes of this study were to describe the physical structure, social significance, and means of sound …

How accurate is translaryngeal ultrasound when compared to flexible nasal endoscopy in viewing vocal cord mobility in children?
… the gold standard for assessment of true vocal cord (TVC) mobility but is invasive and not without risk. The COVID-19 pandemic has led to growing interest in assessment tools that avoid aerosol generation and risk for transmission of disease. Transcutaneous laryngeal ultrasonography (TLUS) …

The Music Muse
… determined by the resonant frequencies of the vocal tract. These resonances are called formants. When a harmonic that is produced by the vocal cords has a frequency that is at or near a formant frequency, it is amplified. Formants are determined by the length, size, and shape of the vocal …

An investigation of endotracheal intubation and alternative intubation devices for use by paramedics in out-of-hospital care
… which was attributed to the good view of the vocal cords the device provided, alongside the ease of use. Further research on ETI and the use of AIDs by paramedics in clinical practice is required, as this was a mannikin study carried out in a controlled environment. Recommendations for a …

Masks and tubes used to support the neonatal airway – how to improve their fit, seal and correct placement
… make it easier to direct the tube through the vocal cords. The final work of the thesis is a review that examines devices used during newborn stabilization. Evidence for their use to optimize the thermal, respiratory and cardiovascular management in the delivery room is presented. After …

The Decelluarized Human Umbilical Vein (HUV) as an Allogeneic Scaffold for Vocal Fold Tissue Engineering
… of which are similar to those present in the vocal fold lamina propria. The vocal fold undergoes vibrations at relatively large amplitudes (1-2mm) and relatively high frequencies (100- 300Hz), thus requiring a scaffold that could endure such mechanical stimuli. The lamina propria consists of …

The diagnostic test accuracy of clinical swallow assessment for oropharyngeal aspiration: a systematic review.
… of food and/or fluids below the level of the vocal cords, can result in a range of complications including: chronic lung diseases, aspiration pneumonia, malnutrition and/or dehydration. Video fluoroscopic swallow study is the Gold Standard assessment of oropharyngeal aspiration but is resource …
