Show moreThis dissertation investigates the phonetic and phonological characteristics of Danish stop consonants, with particular focus on their diachronic origin and synchronic variation. Using data-oriented and statistical methods, it fills empirical gaps in phonetic research on Danish stops and in doing so contributes to our understanding of the overall sound system of the language.The dissertation reports the results of a number of studies which combine spontaneous speech corpora with state-of-the-art techniques in statistical modeling. Topics considered include intervocalic voicing, which is shown to be rare in all stops and in almost all phonetic contexts, and affrication of aspirated stop releases, which is shown to be strongly dependent on place of articulation. The dissertation also investigates a range of phonetic parameters in a legacy corpus of traditional varieties of Jutland Danish, with the results showing systematic regional variation even in minute acoustic details.

Show moreThe acoustic characteristics of noise from fricatives and stop releases are difficult to analyze. The spectral characteristics of such noise are multi-dimensional, and popular methods for analyzing them typically rely on reducing this complex information to one or a few discrete numbers, such as spectral moments or coefficients of discrete cosine transformations. In this paper, I propose using function-on-scalar regression models as a method for analyzing and mass-comparing spectra with minimal reduction of the complexity in the signal. The method is further useful for analyzing how spectra change as a function of time. The usefulness of this method is demonstrated with a corpus analysis of Danish aspirated stop releases, using the DanPASS corpus. The analysis finds that /t/ releases are invariably affricated; /k/ releases are highly affected by coarticulatory context; and /p/ releases are almost always dominated by aspiration in the latter half of the release, but are affricated in the first half in certain contexts.
