South Swedish diphthongisation: an articulographic and acoustic study of /u:/ in the Malmöhus dialect
- 2012
-
Ingår i: Proceedings from FONETIK 2012. - 9789163709852 ; , s. 85-88

Konferensbidrag (refereegranskat)abstract
- We investigated lip and tongue movements of diphthongisation of /uː/ in the Malmöhus dia- lect, which is spoken in the very south of Swe- den. Articulographic and acoustic data of ten native speakers were collected and analysed. Acoustic analysis revealed fairly stable F1 and F3, but a considerable F2 movement through- out the diphthongisation, indicating that /uː/ is realised dynamically. Articulographic results confirmed the acoustic results, showing signifi- cant differences in tongue displacement throughout the diphthong for all speakers, whereas lip displacement differences were sig- nificant for fewer speakers.

Swedish word stress in optimality theory
- 2001
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this paper is to give an introduction to how lexical word stress in Swedish can be analysed with modern phonological theories as metrical phonology (Liberman 1975) and optimality theory (Prince & Smolensky 1993). Central concepts and structures within the phonological theories are introduced and discussed, and examples of how the word stress pattern of Swedish can be treated within optimality theory (OT) are given. We will deal both with monomorphemic words, as well as compound words and affixes.

Tongue articulation of front close vowels in Stockholm, Gothenburg and Malmöhus Swedish
- 2015
-
Ingår i: Proceedings of ICPhS 2015. - 2412-0669. - 9780852619414
-
Konferensbidrag (refereegranskat)abstract
- Articulatory data were collected for the Swedish vowels /iː, yˌ, ʉ̟ː/ from nine speakers each of Stockholm, Gothenburg, and Malmöhus Swedish, and the tongue positions and their dynamics analysed using Functional Data Analysis (FDA). Results showed that the general tongue positions for /iː/ and /yː/ are similar and clearly different from /ʉ̟ː/ in all three dialects. Variation within the Stockholm and Gothenburg groups led to a subdivision into two types, where the tongue positions of type 1 resem-bled Malmöhus Swedish more. Several differences in tongue articulation between types 1 and 2 were observed, possibly explained by the presence of Viby-coloured /iː/ and /yː/ in type 2.

Konferensbidrag (refereegranskat)abstract
- In this paper we develop a system for detection of word-related head movements in audiovisu-al recordings of read news. Our materials consist of Swedish television news broadcasts and comprise audiovisual recordings of five news readers (two female, three male). The corpus was manually labelled for head movement, applying a simplistic annotation scheme consisting of a binary decision about absence/presence of a movement in relation to a word. We use OpenCV for frontal face detection and based on this we calculate velocity and acceleration features. Then we train a machine learning system to predict absence or presence of head movement and achieve an accuracy of 0.892, which is better than the baseline. The system may thus be helpful for head movement labelling.

Vowel reduction and the perception of words
- 1998
-
Ingår i: Fonetik 98 : proceedings. - 9189192036 ; , s. 36-39
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This study deals with listeners' ability to identify linguistic units from linguistically incomplete stimuli and relates this to the potentiality of vowel reduction in a word. Synthetic speech was used to produce stimuli that were similar to real words, but where the vowel in the pre-stress syllable was excluded. Listeners then performed a lexical decision test, where they had to decide whether a stimulus sounded like a word or not. The effects of the identity of the removed vowel and of features of the consonants adjacent to the removed vowel were then examined. For type of vowel, lower word rates where found for words with the vowels /a/ and /o/, whereas words with nasals after the reduced vowel tended to result in higher word rates.
