Abstract
This paper introduces FormantPro, a Praat-based tool for large-scale, systematic analysis of formant movements, especially for experimental data. The program generates a rich set of output metrics, including continuous contours like time-normalized formant trajectories and formant velocity profiles suitable for direct graphical comparisons, and discrete measurements suitable for statistical analysis. It also allows users to generate mean trajectories and discrete measurements averaged across repetitions and speakers. As an illustration of its usage, data from a preliminary study of syllable segmentation in Mandarin were presented. The alignment of continuous formant trajectories enabled by FormantPro provides evidence that the temporal scopes of consonants and vowels are very different from those based on conventional views, and that acoustic and articulatory boundaries of segments are fundamentally similar.
