ProsoDyn: a graphical representation of macroprosody for phonostylistic ambiance change detection

Following the ProsoReport, we present a new prosodic tool in Praat allowing a dynamic analysis of prosodic dimensions such as temporal, intonational and accentual parameters, to graphically represent the macro-prosodic variations in Praat. It helps the user to visually detect “ambiance changes” that are supposed to be significant. Two different graphical modes can be activated at the same time: parameters averaged relative to an external macro-segmentation (e.g. utterance, speaker's turns, etc.) and relative to a sliding window for a representation of local speech rate and register. Interactive buttons allow the adjustment of scales and help the user to explore data a macroprosodic level
