Sammanfattning : The overall aim of the thesis was to develop new methods for analysis of vocal fold vibrations and viscoelasticity and to test them in human subjects. In Study I the onset of vibration and irregular vocal fold vibration was examined with laryngoscopy using a high-speed camera at a frame rate of about 2000 images/sec. LÄS MER

Sammanfattning : The human voice is a product of an intricate biophysical system. The complexity of this system enables a rich variety of possible sounds, but at the same time poses great challenges for quantitative voice analysis. For example, the vocal folds can vibrate in several different ways, leading to variations in the acoustic output. LÄS MER

Sammanfattning : This thesis consists of five articles and a summary. Thethesis deals with methods for measuring properties of thevoice. The methods are all computer-based, but utilisedifferent approaches for measuring different aspects of thevoice.Paper I introduces the Visual Sort and Rate (VSR) method forperceptual rating of voice quality.

Sammanfattning : Vocal fold vibration results from an alternating balance between subglottal air pressure that drives the vocal folds apart and muscular, elastic, and restoring forces that draw them together. The aim of the present thesis is to present quantitative data of normal vocal function using a noninvasive method. LÄS MER

Sammanfattning : The human upper airways embrace the source of phonation and affect the modulation of the voice, which is of vital importance for communication. Moreover, unwanted sounds may be generated in the upper airways due to elastic, collapsible parts that are susceptible to flow-induced vibration and resonance. LÄS MER
