Stop! Hey, what's that sound?: the representation and realization of Danish stops

This 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.Theoretical and Experimental Linguistic

The rarity of intervocalic voicing of stops in Danish spontaneous speech

Previous studies of the phonetics of Danish stops have neglected closure voicing. Danish is an aspiration language, but the aspirated stops /p t k/ are produced with shorter closure duration and less articulatory effort than the unaspirated stops /b d ɡ/. Furthermore, all Danish stops are characterized by some degree of glottal spreading during the closure. In this study, we use a corpus of Danish spontaneous speech (DanPASS) to investigate the intervocalic voicing—its distribution across the two laryngeal categories, whether it patterns as a lenition phenomenon, and whether the aerodynamic environment predicts its distribution. We find that intervocalic voicing is not the norm for either set of stops and is particularly rare in /p t k/. Voiced tokens are mostly found in environments associated with lenition. We suggest that the glottal spreading gesture found in all Danish stops is a phonological mechanism blocking voicing, which is probabilistically lost in spontaneous speech. This predicts our results better than relying on laryngeal features like [voice] or [spread glottis]. The study fills a gap in our knowledge of Danish phonetics and phonology, and is also one of the most extensive corpus studies of intervocalic stop voicing in an ‘aspiration language.’Theoretical and Experimental LinguisticsDescriptive and Comparative Linguistic
