Speech Rate as a Reflection of Variance and Invariance in Conceptual Planning In Storytelling

Janice Fon

The Ohio State University, USA

This study investigates conceptual planning and cognitive rhythm as they may be reflected in speech rate fluctuation. According to the hierarchy principle, speech rate is slower when higher level planning is at work and faster when the planning is complete. Two four-frame comic strips were used to elicit speech. Speech rate was calculated in terms of syllables per second and a low-pass smoothing filter was used to reduce the impact of idiosyncratic fluctuation contributed by individual syllables. Results showed that most speakers were sensitive to story structures, although their narration strategies varied. Speakers aimed for planning units that accommodated story part boundaries. A solely clause-based planning strategy is not preferred.
