- This paper studies how confirmations are intoned by nine speakers of Southern Swedish. Test phrases like ja, det var med bilen/bilar ‘yes, it was by car’ (Accent 1)/‘...with cars’ (Accent 2) were elicited, both as new-information responses and confirmations. Speakers made a clear distinction between the utterance types using two, simultaneous intonation strategies. First, they realised the nuclear accent on the target word with a considerably lower F0 peak in con- firmations than in new-information responses. Second, they added a pre-nuclear accent on the verb in confirmations. While they maintained the word-accent distinction on the target word in confirmations, the encoding of the word accent (Accent 1) on the verb seemed to be op- tional. This suggests that the pre-nuclear accent serves a primarily intonational function and that Southern Swedish may have purely intonational pitch accents, contrary to the traditional view.

Perceiving head movements in news readings : Evidence from web-based auditory vs. audiovisual prominence ratings

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Previous research has shown that visual information can be integrated in the perception of prominence, but the available evidence stems mostly from controlled experimental settings, often making use of synthetic stimuli. The present study provides evidence from spontaneously produced head gestures that occurred in Swedish television news readings. Materials were rated for word prominence by 85 adult volunteers in a between-subjects design (audio-visual vs. audio-only ratings) using a crowd-sourcing approach. Accented words accompanied by a head movement were perceived as more prominent than accented words lacking a head movement. Crucially, the difference in perceived prominence level between words with and without a head gesture was found to be larger in an audio-visual rating condition compared to an audio-only condition. The results suggest that visual prominence signals are integrated in speech processing even in a relatively uncontrolled, naturalistic setting, such as watching the news.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents a pilot study on the prosodic marking of a contrastive topic in Southern Swedish. A test sentence was elicited in three experimental conditions: initial focus; final focus; contrastive topic (initial word) plus focus (final word). F0 patterns were analysed in recordings of 10 speakers. A majority of the speakers distinguished clearly between the conditions, but speakers employed different strategies. The most common one involved modifying the range and/or level of the F0 patterns given by the lexical pitch accents. Another frequent strategy involved a rising pitch accent on the initial word, where the lexical pitch accent would normally stipulate a fall. This result was unexpected and indicates that Southern Swedish sentence intonation might be more complex than typically assumed.

- Prosodic prominence is a multimodal phenomenon where pitch accents are frequently aligned with visible movements by the hands, head, or eyebrows. However, little is known about how such movements function as visible prominence cues in multimodal speech perception with most previous studies being restricted to experimental settings. In this study, we are piloting the acquisition of multimodal prominence ratings for a corpus of natural speech (Swedish television news readings). Sixteen short video clips (218 words) of news readings were extracted from a larger corpus and rated by 44 native Swedish adult volunteers using a web-based set-up. The task was to rate each word in a clip as either non-prominent, moderately prominent or strongly prominent based on audiovisual cues. The corpus was previously annotated for pitch accents and head movements. We found that words realized with a pitch accent and head movement tended to receive higher prominence ratings than words with a pitch accent only. However, we also examined ratings for a number of carefully selected individual words, and these case studies suggest that ratings are affected by complex relations between the presence of a head movement and its type of alignment, the word's F0 profile, and semantic and pragmatic factors.

- Objective. To determine the prevalence of diabetes and impaired glucose tolerance after gestational diabetes mellitus in relation to different categories of glucose tolerance during pregnancy. Design. Prospective study. Setting. Four delivery departments and three hospitals in southern Sweden took part in recruitment and follow-up. Population. Women undergoing a 75 g oral glucose tolerance test during pregnancy delivering in 2003-2005. Methods. At first follow-up, 1-2 years after delivery, 29% of eligible women with abnormal glucose tolerance during pregnancy had an oral glucose tolerance test; 160 with gestational diabetes, 309 with gestational impaired glucose tolerance, in addition to 167 control women. Cut-off levels defining gestational diabetes and impaired glucose tolerance were 2-hour capillary blood glucose levels 9.0 and 7.8 mmol/l or plasma glucose 10.0 and 8.6 mmol/l, respectively. Main outcome measures. Frequency of abnormal test results at follow-up. Results: Diabetes was diagnosed in 11% and impaired glucose tolerance in 24% of women with gestational diabetes vs. 4% and 23% in those with gestational impaired glucose tolerance. Combining women with abnormal test results during pregnancy revealed diabetes or impaired glucose tolerance in 29% as compared to 10% among controls; the odds ratio (95% confidence interval) for having abnormal test results was 3.3 (1.8-5.9) in a multivariate logistic regression analysis. Conclusions: Lowering the cut-off level for gestational diabetes to also include the category of impaired glucose tolerance would identify a high percentage of women with diabetes and impaired glucose tolerance postpartum, they constitute target groups for intervention and/or diabetes prevention.

The role of affective meaning, semantic associates, and orthographic neighbours in modulating the N400 in single words

- The N400 has been seen to be larger for concrete than abstract words, and for pseudowords than real words. Using a word vector analysis to calculate semantic associates (SA), as well as ratings for emotional arousal (EA), and a measure of orthographic neighbourhood (ON), the present study investigated the relation between these factors and N400 amplitudes during a lexical decision task using Swedish word stimuli. Four noun categories differing in concreteness: specific (squirrel), GENERAL (animal) emotional (happiness) and abstract (tendency) were compared with pseudowords (danalod). Results showed that N400 amplitudes increased in the order emotional < abstract < GENERAL < specific < PSEUDOWORD. A regression analysis showed that the amplitude of the N400 decreased the more semantic associates a word had and the higher the rating for emotional arousal it had. The N400 also increased the more orthographic neighbours a word had. Results provide support for the hierarchical organisation of concrete words assumed in lexical semantics. They also demonstrate how affective information facilitates meaning processing.
