SEA_AP: a segmentation and labelling tool for prosodic analysis

Paula López Otero, Laura Docío Fernández, Carmen García Mateo, Marta Martínez Maquieira, Rocío Varela Fernández, Elisa Fernández Rei


This paper introduces a tool that performs segmentation and labelling of sound chains in phono units, syllables and/or words departing from a sound signal and its corresponding orthographic transcription. In addition, it also integrates acoustic analysis scripts applied to the Praat programme with the aim of reducing the time spent on tasks related to analysis, correction, smoothing and generation of graphics of the melodic curve. The tool is implemented for Galician, Spanish and Brazilian Portuguese. Our goal is to contribute, by means of this application, to automatize some of the tasks of segmentation, labelling and prosodic analysis, since these tasks require a large investment of time and human resources.
