Figure 2
Data preprocessing: a sketch of the pipeline applied to one condition for one representative participant. The left column shows the acoustic signal of each trial in gray, with its corresponding envelope over-imposed in pink. Trials 1 and 2 are whispered (Whis = 1), and trial seven is voiced (Whis = 0). Arrows point to the reaction time. The middle column displays the spectrum of the envelope for each test. Arrows indicate the syllabic rate (fMAX). The right panel shows the correlation matrix of the envelope spectra (Sp1–7) with its lower diagonal elements highlighted in gray. The rhythmic structure consistency across trials was computed as the average of these elements.
