A Multi-Dimensional Pipeline for Holistic Prosodic Visualization: Integrating f0, Intensity, and Syllabic Rate using VIP2VIP

Most visualizations used in speech prosody research privilege a single acoustic dimension (typically f0), leaving key correlates of prominence, phrasing, and rhythm only indirectly inferable. We present VIP2VIP – Visualize Intonation and Prosody for Voices of Italian Poets: a new, open pipeline for multi-dimensional intonation visualization that renders (I) an f0 contour smoothed by LOWESS or GAM, (II) instantaneous intensity (as line thickness), and (III) syllabic rate (SR; syllables/s) projected onto the f0 trace as a perceptually ordered colour ramp. The visualization operates over light, reproducible annotations and is robust to micro-prosodic noise. It is intended as a descriptive tool that remains compatible with superpositional theories: global phrase-level trends and local accentual movements can be inspected together with temporal density and energy. We detail the method and its User Interface, illustrate analyses on Italian poetic read speech, and compare this approach to f0-only and stylization-based tools. We suggest that compressing these three dimensions into a single coordinated display may facilitate hypothesis generation, while remaining usable alongside formal modelling frameworks such as Fujisaki’s or Grønnum’s approach.
