The perceptual relevance of changes to glottal-pulse parameters is studied. First, it is demonstrated that a distance measure based on excitation patterns can predict audibility discrimination thresholds for small changes to the R parameters of the Liljencrants-Fant (LF) model. Next, by using this measure the perceptual relevance of the LF parameters is… (More)
The work described in this thesis has been carried out under the auspices of the J.F.
Pulse-resonance sounds like vowels or instrumental tones contain acoustic information about the physical size of the sound source (pulse rate) and body resonators (resonance scale). Previous research has revealed correlates of these variables in humans using functional neuroimaging. Here, we report two experiments that use magnetoencephalography to study… (More)
Mood is an important aspect of music and knowledge of mood can be used as a basic feature in music recommender and retrieval systems. A listening experiment was carried out establishing ratings for various moods and a number of attributes, e.g., valence and arousal. The analysis of these data covers the issues of the number of basic dimensions in music… (More)
This paper describes a method for analysing the perceptual relevance of parameter variations of the Liljencrants– Fant (LF) model for the glottal pulse. A perceptual distance measure based on excitation patterns was developed and evaluated in order to predict audibility discrimination thresholds for small changes to the R-parameters of the LF model. For a… (More)
