  2. 1. Electroglottographic analysis of phonatory dynamics and states

    Author : Andreas Selamtzis; Sten Ternström; Malte Kob; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; voice function; phonation; vocal fold vibration; vocal registers; electroglottography;

    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

  4. 2. Analyses of voice and glottographic signals in singing and speech

    Author : Andreas Selamtzis; Sten Ternström; Paavo Alku; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; voice ; singing ; electroglottography ; clustering ; dysphonia ; sample entropy ; ; Tal- och musikkommunikation; Speech and Music Communication;

    Abstract : 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.

  5. 3. Breathing and phonation : effects of lung volume and breathing behaviour on voice function

    Author : Jenny Iwarsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Abduction; Adduction; Breathing; Flow glottogram; Inhalation; Lung volume; Perceptual analysis; Phonation; Posture; Speech lung volume; Speech task; Subglottal pressure; Tracheal pull; Vertical laryngeal position; Vocal fold nodules; Voice source;

    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
