Acoustic Mediation Of Vocalized Emotion Identification: Do Decoders Identify Emotions Idiographically Or Nomothetically?, Michael Kenneth Lauritzen
Acoustic Mediation Of Vocalized Emotion Identification: Do Decoders Identify Emotions Idiographically Or Nomothetically?, Michael Kenneth Lauritzen
Theses and Dissertations
Most research investigating vocal expressions of emotion has focused on one or more of three questions: whether there exist unique acoustic profiles of individual encoded emotions, whether the nature of emotion expression is universal across cultures, and how accurately decoders can identify expressed emotions. This dissertation begins to answer a fourth question, whether there exist unique patterns in the types of acoustic properties persons focus on to identify vocalized emotions. Three hypotheses were tested: first, whether acoustic patterns are interpreted idiographically or nomothetically as reflected in a comparison of individual vs. group lens model identification ratios; second, whether there exists …

Associations Between Linguapalatal Contact Patterns And Spectral Moments For /S/, Leslie Leatham Bennett
Theses and Dissertations
Both acoustic and palatographic measures have proven to be useful in speech science research. However, it is not known how closely or consistently these two measures are associated with each other. Therefore, this study investigated the association between changes in tongue-to-palate contact patterns and simultaneous changes in acoustic spectral moments for the fricative /s/. Twenty adults were fitted with pseudopalates and repeated VCV nonsense syllables consisting of an initial schwa followed by the target consonant /s/ and ending with one of three corner vowels (/i, ɑ, u/). EPG (electropalatography) data were quantified using three custom numerical indices (s-narrow, s-wide, and …

Objectives: The goal of this investigation was to test a new methodology for measuring amplitude modulation (AM) at the level of the vocal folds during vibrato in trained singers, because previous research has suggested that AM arises in large part as an acoustic epiphenomenon through an interaction of the harmonics in the laryngeal source with the resonances of the vocal tract as the fundamental frequency oscillates.
Study Design: A within-subjects model was used to compare vocal activity across three pitch and three loudness conditions.
Methods: Seventeen female singers with a range of training and experience were recorded with a microphone …
