1. Alternative Measures of Phonation: Collision Threshold Pressure and Electroglottographic Spectral Tilt : Extra: Perception of Swedish Accents
Sammanfattning : 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. LÄS MER
2. Putting the Singing Voice on the Map : Towards Improving the Quantitative Evaluation of Voice Status in Professional Female Singers
Sammanfattning : Diagnostic and evaluative methods used in voice care are mostly designedfor the speaking voice, and are not necessarily directly applicable to thesinging voice. This thesis investigated the possibilities of fine tuning, improvingand quantifying the voice status assessment of the singer, focusingespecially on the Western operatic female voice. LÄS MER
3. Mapping Individual Voice Quality over the Voice Range : The Measurement Paradigm of the Voice Range Profile
Sammanfattning : The acoustic signal of voiced sounds has two primary attributes: fundamental frequency and sound level. It has also very many secondary attributes, or ‘voice qualities’, that can be derived from the acoustic signal, in particular from its periodicity and its spectrum. LÄS MER
Sammanfattning : Recent advances in machine learning and time series analysis techniques have brought new perspectives to a great number of scientific fields. This thesis contributes applications of such techniques to voice analysis, in an attempt to extract information on the vibration of the vocal folds as such, as well as on the radiated acoustic signal.

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
