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 moreThis thesis describes several patterns of phonetic variation in Sign Language of the Netherlands. While lexical variation between different regions has been found in the Netherlands, little is known about phonetic or phonological variation. Phonetic variation in the realization of some of the traditional handshape and orientation features is analyzed in detail. Furthermore, data were elicited from different registers: short-distance signing (__whispering__) was compared to long-distance signing (__shouting__). Results show that differences between registers lead not only to variation in movement size, but also to changes in the traditional phonological categories. In enlarged realizations, as in shouting, handshape and orientation changes may be enhanced by a location change; in reduced forms, as in whispering, location changes may be realized as changes in orientation or handshape. While the distinction between the three parameters handshape, orientation and location remains valid, it is argued that their definition needs to be stated in global perceptual targets rather than in detailed articulatory terms in a comprehensive analysis of the various differences between registers. The data thus provide evidence for a strict separation of perceptual and articulatory characterizations of signs. The lexical specification contains only perceptual targets. The variation is thus not generated by a phonological process, but is a matter of phonetic implementation. Show less
