What is the \u2018shape\u2019 of phrasal pitch contours, analyzed in terms of their component phonological features or in acoustic F0 measurements? How does intonation function to mark the structure of phrases and larger discourse units, or distinctions in semantic or pragmatic meaning? The goal of a linguistic theory of intonation is to establish a framework in which the form and functions of intonation can be analyzed and compared across languages and speakers. This is a surprisingly difficult task. Analyzing the function of intonational expressions calls for preliminary decisions about segmentation, measurement and encoding\u2013 which interval(s) of a continuous pitch signal are associated with a particular meaning or structure, which aspects of the dynamic F0 signal encode that function, and what are the features of encoding? Even for English, arguably one of the most studied intonation systems, there is ongoing debate over these very questions, resulting in a knowledge bottleneck that stymies scientific progress on intonation and its communicative function.\r\nIn this talk I report on my recent work addressing this central challenge for American English: What are the characteristics of phrasal pitch patterns that are reliably perceived and produced as distinct and interpreted differently, by speakers of the language? I discuss findings from parallel streams of research in my lab investigating intonational form and its pragmatic function. Part I (work with Jeremy Steffman) relates a series of studies that examine intonational form through imitations 16 intonational \u201ctunes\u201d of English, under varying task conditions that tap memory representations of model tunes presented auditorily. Analyses of dynamic F0 patterns from five experiments converge on finding a robust, primary distinction between high-rising and low-falling tunes, and smaller, secondary F0 distinctions within both classes. Part II (work with Thomas Sostarics) focuses on the pragmatic function of tunes, presenting findings from one experiment testing asking\/telling interpretations for stimuli from a two-dimensional Rising-Falling continuum, and another examining the facilitation of scalar inference as a function of tune shape (Falling, Rise-Fall-Rise, with varying pitch accents). Findings from both experiments point again to a primary dichotomy between high-rising and low-falling tunes, with secondary distinctions in meaning corresponding to F0 shape variation within the two primary tune classes. Implications of these joint findings are discussed for a theory of categorical and gradient associations of intonational form and function.", "occurrence_notes":null, "guid":"124757-21853737@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/124757", "building_id":"null", "building_name":"Off Campus Location", "campus_maps_id":"1", "room":"East Hall 4448", "location_name":"Hybrid", "has_livestream":1, "livestream_type":"zoom", "livetream_require_login":0, "livestream_id":"98160522966", "livestream_link":"https:\/\/umich.zoom.us\/j\/98160522966", "cost":"", "tags":["Free","Talk"], "website":"", "sponsors":[ { "group_name":"Department of Linguistics", "group_id":"3480", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2024\/10\/event_124757_original-3.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2024\/10\/event_124757_original-3.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2024\/10\/event_124757_original-3.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2024\/10\/event_124757_original-3.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2024\/10\/event_124757_original-3.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2024\/10\/event_124757_original-3.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2024\/10\/event_124757_original-3.png" }, "occurrence_count":1, "first_occurrence":21853737 } }
