- Prosody and gesture share common functions in communication, one of which is the signaling of prominence. However, we still know relatively little about how these two domains are coordinated with one another. The current study explores timing relationships between hand gestures and stressed syllables in Swedish compounds. Compounds in Swedish usually have two stressed syllables, enabling us to investigate possible differences in alignment between gestures and stressed syllables as a function of their phonological status (primary, secondary stress). We find a tendency for stressed syllables to be accompanied by movement phases of gestures, with the primary stressed syllable somewhat more likely to arise with a movement phase than the secondary stressed syllable. The stressed syllables also show tendencies for close temporal alignment with transitions between one gesture phase to another, though not all gesture phase types may start in alignment with the second stressed syllable. Our data thus provide additional support for the common function of prosody and gesture in signaling prominence in spoken communication and indicate that transitions between gesture phases as well as the gestures themselves may contribute to prominence marking.

Konferensbidrag (refereegranskat)abstract
- Glottalization is often associated with low pitch in intonation languages, but evidence from many languages indicates that this is not an obligatory association. We asked speakers of German, English and Swedish to compare glottalized stimuli with several pitch contour alternatives in an AXB listening test. Although the low F0 in the glottalized stimuli tended to be perceived as most similar to falling pitch contours, this was not always the case, indicating that pitch perception in glottalization cannot be predicted by F0 alone. We also found evidence for cross-linguistic differences in the degree of flexibility of pitch judgments in glottalized stretches of speech.

- Although glottalization has often been associated with lowpitch, evidence from a number of sources supports theassertion that this association is not obligatory, and is likely tobe language-specific. Following a previous study testingperception of glottalization by German, English, and Swedishlisteners, the current research investigates the influence ofpitch context on the perception of glottalization by nativespeakers of a tone language, Mandarin Chinese. Listenersheard AXB sets in which they were asked to match glottalizedstimuli with pitch contours. We find that Mandarin listenerstend not to be influenced by the pitch context when judgingthe pitch of glottalized stretches of speech. These data lendsupport to the idea that the perception of glottalization variesin relation to language-specific prosodic structure.

Cues to next-speaker projection in conversational Swedish: Evidence from reaction times
- 2023

Ingår i: Interspeech 2023. - : International Speech Communication Association. ; , s. 1040-1044
-
Konferensbidrag (refereegranskat)abstract
- We present first results of a study investigating the salience and typicality of prosodic markers in Swedish at turn ends for turn-yielding and turn-keeping purposes. We performed an experiment where participants (N=32) were presented with conversational chunks and, after the audio ended, were asked to determine which of two speakers would speak next by clicking a picture on a screen. Audio stimuli were manipulated by (i) raising and (ii) lowering f0 over the last 500 ms of a turn, (iii) speeding up or (iv) slowing down duration over the last 500 ms, and (v) raising and (vi) lowering the last pitch peak. In our data, out of all manipulations, increasing the speech rate was found to be the most disruptive (p < .005). Higher speech rate led to longer reaction times in turn-keeping, which were shorter in turn-yielding. Other manipulations did not significantly alter reaction times. The results presented here may be complemented with eye movement data, to further elucidate cognitive mechanisms underlying turn-taking behavior.

Can segmental or syllabic durations be predicted by the presence of co-speech gestures?

- Building on insights from the coordination of speech and gesture, the cumulative cue hypothesis proposes that speakers recruit cues from both modalities to signal prominence and that the relationship between the cues is additive as opposed to compensative. The study tests if durational variation is one of the cues that are recruited in this cumulative fashion in accord with gestural cues by analysing three five-minute dialogue chunks of spontaneous Swedish. The results do not indicate a direct covariation of this cue with the presence or absence of gestural cues, pointing instead to a need for further investigation of the role of duration in multimodal prominence production and perception.

Temporal alignment of manual gestures’ phase transitions with lexical and postlexical accentual F0 peaks in spontaneous Swedish interaction

Konferensbidrag (refereegranskat)abstract
- Many studies investigating the temporal alignment of co-speech gestures to acoustic units in the speech signal find a close coupling of the gestural landmarks and pitch accents or the stressed syllable of pitch-accented words. In English, a pitch accent is anchored in the lexically stressed syllable. Hence, it is unclear whether it is the lexical phonological dimension of stress, or the phrase-level prominence that determines the details of speech-gesture synchronization. This paper explores the relation between gestural phase transitions and accentual F0 peaks in Stockholm Swedish, which exhibits a lexical pitch accent distinction. When produced with phrase-level prominence, there are three different configurations of lexicality of F0 peaks and the status of the syllable it is aligned with. Through analyzing the alignment of the different F0 peaks with gestural onsets in spontaneous dyadic conversations, we aim to contribute to our understanding of the role of lexical prosodic phonology in the co-production of speech and gesture.The results, though limited by a small dataset, still suggest differences between the three types of peaks concerning which types of gesture phase onsets they tend to align with, and how well these landmarks align with each other, although these differences did not reach significance.

- This study adopts a multiple-methods approach to the investigation of prosody, drawing on insights from a quantitative methodology (experimental prosody research) as well as a qualitative one (conversation analysis). We use a k-means cluster analysis to investigate prosodic patterns in conversational sequences involving lexico-semantic contrastive structures. This combined methodology demonstrates that quantitative/statistical methods are a valuable tool for making relatively objective characterizations of acoustic features of speech, while qualitative methods are essential for interpreting the quantitative results. We find that in sequences that maintain global prosodic characteristics across contrastive structures, participants orient to interactional problems, such as determining who has the right to the floor, or avoiding disruption of an ongoing interaction. On the other hand, in sequences in which the global prosody is different across contrastive structures, participants do not generally appear to be orienting to such problems of alignment. Our findings expand the interpretation of "contrastive prosody" that is commonly used in experimental prosody approaches, while providing a way for conversation-analytic research to improve quantification and generalizability of findings.

Perception of pitch tails at potential turn boundaries in Swedish
- 2014
-
Ingår i: Proceedings of the Annual Conference of the International Speech Communication Association. ; , s. 1944-1948
-
Konferensbidrag (refereegranskat)abstract
- In a number of languages, intonational patterns at prosodic boundaries are considered to be relevant for turn transition or turn hold. A perception experiment tested the influence of fundamental frequency (F0) peak height and rising final contours on Swedish listeners’ judgment about whether a speaker wanted to hold the turn. While F0 peak height, as has been previously shown, did influence listeners’ judgments, the end height of rising pitch tails apparently did not influence listeners’ judgments about whether a speaker planned to continue talking, even though they showed sensitivity to the differences in a discrimination task. The differences in responses in the tasks, as well as the difference from results found for other languages, may indicate that listeners used comparative prominence to guide their judgments, rather than intonation playing a direct role in the turn-transition system.

Pitch and lengthening as cues to turn transition in Swedish
- 2013
-
Ingår i: Proceedings of Interspeech 2013. ; , s. 248-252
-
Konferensbidrag (refereegranskat)abstract
- In many cases of turn transition in conversation, a new speaker may respond to phonetic cues from the end of the prior turn, including variation in prosodic features such as pitch and final lengthening. Although consistent pitch and lengthening features are well-established for some languages at potential points of turn transition, this is not necessarily the case for Swedish. The current study uses a two-alternative forced choice task to investigate how variation in pitch contour and lengthening at the ends of syntactically complete turns can influence listeners’ expectations of turn hold or turn transition. Both lengthening and pitch contour features were found to influence listeners’ judgments about whether turn transition would occur, with shorter length and higher final pitch peaks associated with turn hold. Furthermore, listeners were more certain about their judgments when asked about turn-hold rather than turn-change, suggesting an imbalance in the strength of turn-hold versus turn-transition cues.

Prosodic Variation and Segmental Reduction and Their Roles in Cuing Turn Transition in Swedish
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Prosody has often been identified alongside syntax as a cue to turn hold or turn transition in conversational interaction. However, evidence for which prosodic cues are most relevant, and how strong those cues are, has been somewhat scattered. The current study addresses prosodic cues to turn transition in Swedish. A perception study looking closely at turn changes and holds in cases where the syntax does not lead inevitably to a particular outcome shows that Swedish listeners are sensitive to duration variations, even in the very short space of the final unstressed syllable of a turn, and that they may use pitch cues to a lesser extent. An investigation of production data indicates that duration, and to some extent segmental reduction, demonstrate consistent variation in relation to the types of turn boundaries they accompany, while fundamental frequency and glottalization do not. Taken together, these data suggest that duration may be the primary cue to turn transition in Swedish conversation, rather than fundamental frequency, as some other studies have suggested.

Tidskriftsartikel (refereegranskat)abstract
- Speakers and listeners have been shown to use phonetic cues to help them in tracking the ongoing structure of conversational interaction, but fragmentation between qualitative and quantitative research means that the forms and functions of these cues have been given varying characterizations. The current study explores prosodic variation in contrastive structures in conversational data, using a combined methodology adopting aspects from both qualitative (conversation analysis) and quantitative (experimental phonetics/phonology) approaches. Statistical and conversation-analytical methods used together reveal relationships between prosodic variation and interactional function, such as variations in pitch range across adjacent turns being linked to the presence of 'stepwise' topic changes.
