1. From Air to Aria. Relevance of Respiratory Behaviour to Voice Function in Classical Western Vocal Art
Abstract : While previous studies of opera singersrespiratorybehaviour have focused on kinematic or dynamic aspects mainly,this thesis attempts to adopt a broader perspective. Not onlylung volumes, rib cage and abdominal wall kinematics areconsidered, but also the effects of lung volumes and respiratorybehaviour on phonation characteristics. READ MORE

2. Electroglottographic analysis of phonatory dynamics and states
Abstract : 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. READ MORE

3. The Voice Source in Speech Communication - Production and Perception Experiments Involving Inverse Filtering and Synthesis
Abstract : This thesis explores, through a number of production andperception studies, the nature of the voice source signal andhow it varies in spoken communication. Research is alsopresented that deals with the techniques and methodologies foranalysing and synthesising the voice source. READ MORE

4. Alternative Measures of Phonation: Collision Threshold Pressure and Electroglottographic Spectral Tilt : Extra: Perception of Swedish Accents
Abstract : The collision threshold pressure (CTP), i.e. the smallest amount of subglottal pressure needed for vocal fold collision, has been explored as a possible complement or alternative to the now commonly used phonation threshold pressure (PTP), i.e. READ MORE

5. Breathing and phonation : effects of lung volume and breathing behaviour on voice function
Abstract : Respiration is believed to play a central role in voice function and is thus of relevance to the clinical care of the disordered voice. The overall aim of the present study was to experimentally investigate relationships between the respiratory and phonatory systems. READ MORE
