OBJECTIVE To clarify the influence of an experimental palatal plate on the mandibular position during continuous [n] phonation and at the physiological rest position in complete denture wearers. METHODS Ten complete denture wears volunteers were investigated. Two kinds of experimental palatal plate with a thickness of 3 mm and 5 mm (from the denture basal surface to denture polished surface) ...

Despite the growing number of studies on the acoustics of non-modal phonation, little is known about how two distinct non-modal phonations can interact acoustically when coarticulated. This study investigates the acoustics of potential breathy-to-creaky phonation contours from a production study of native speakers of English, White Hmong, and Korean. These languages differ in the nature of the ...

Work carried out under the ERASMUS exchange programme. The EGG contact quotient (CQegg) is the ratio of the duration of the 'contact phase' to the entire glottal cycle period. Various methods for determining the contacting and de-contacting 'events' and then the CQegg have been advanced by different authors. There are criterion-level methods which look for threshold crossings in the short-term ...

BACKGROUND AND PURPOSE The nature of vocal registers is still a subject of controversy. The purpose of this study was to demonstrate the induction of timbre transition of vocal register in an in vivo evoked phonation canine model and thereby confirm vocal register transition as a laryngeal event. MATERIALS A canine midbrain stimulation evoked phonation model was used in this study. To repeat ...
