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

Area of Science:

• Linguistics
• Phonetics
• Sociolinguistics

Background:

• Prosody and syntax are known cues for conversational turn-taking.
• Previous research on specific prosodic cues in Swedish turn transitions is limited and scattered.
• Understanding these cues is crucial for analyzing conversational dynamics.

Purpose of the Study:

• To investigate the specific prosodic cues signaling turn transitions in Swedish.
• To determine the relative importance of duration, pitch, and other prosodic features.
• To clarify the role of prosody in managing conversational flow in Swedish.

Main Methods:

• A perception study evaluated listener sensitivity to prosodic variations at turn boundaries.
• Production data analysis examined variations in prosodic features across different turn boundary types.
• Focus was placed on unstressed syllables and specific prosodic elements like fundamental frequency and glottalization.

Main Results:

• Swedish listeners are sensitive to duration variations, even in short unstressed syllables, for turn transition.
• Pitch cues play a lesser role in signaling turn transitions compared to duration.
• Production data show consistent duration and segmental reduction variations at turn boundaries, unlike fundamental frequency or glottalization.

Conclusions:

• Duration is likely the primary prosodic cue for turn transition in Swedish conversation.
• Fundamental frequency may be less critical than previously suggested for Swedish turn transitions.
• These findings contribute to a nuanced understanding of prosodic signaling in conversational interaction.
