Reichel"],"abstract":"The purposes of the CoPaSul toolkit are (1) automatic prosodic annotation and\n(2) prosodic feature extraction from syllable to utterance level. CoPaSul\nstands for contour-based, parametric, superpositional intonation stylization.\nIn this framework intonation is represented as a superposition of global and\nlocal contours that are described parametrically in terms of polynomial\ncoefficients. On the global level (usually associated but not necessarily\nrestricted to intonation phrases) the stylization serves to represent register\nin terms of time-varying F0 level and range. On the local level (e.g. accent\ngroups), local contour shapes are described. From this parameterization several\nfeatures related to prosodic boundaries and prominence can be derived.\nFurthermore, by coefficient clustering prosodic contour classes can be obtained\nin a bottom-up way. Next to the stylization-based feature extraction also\nstandard F0 and energy measures (e.g. mean and variance) as well as rhythmic\naspects can be calculated. At the current state automatic annotation comprises:\nsegmentation into interpausal chunks, syllable nucleus extraction, and\nunsupervised localization of prosodic phrase boundaries and prominent\nsyllables. F0 and partly also energy feature sets can be derived for: standard\nmeasurements (as median and IQR), register in terms of F0 level and range,\nprosodic boundaries, local contour shapes, bottom-up derived contour classes,\nGestalt of accent groups in terms of their deviation from higher level prosodic\nunits, as well as for rhythmic aspects quantifying the relation between F0 and\nenergy contours and prosodic event rates.","url_abs":"http://arxiv.org/abs/1612.04765v9","url_pdf":"http://arxiv.org/pdf/1612.04765v9.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"copasul-manual-contour-based-parametric-and","repo_url":"https://github.com/reichelu/copasul","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"clustering","task_name":"Clustering"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
