{"pk":27903,"title":"Game Theoretic Models of Clear versus Plain Speech","subtitle":null,"abstract":"Clear speech is a vocal style used when a speaker wishes to im-prove comprehension, usually due to the presence of externalnoise, less-than-optimal listening conditions, or when they aresimply instructed to speak clearly. Clear speech has many dis-tinguishing features, including increased duration, pitch, andamplitude, as well as the exaggeration of articulatory move-ment. We use game theory to model the phenomenon of clearspeech, and make predictions of how it changes under differ-ent circumstances. We view the behaviours of speakers andhearers when communicating as optimal strategies in commu-nication games. When comprehension becomes more difficult,the optimal strategies of the games shift so that speakers exertmore energy to improve the likelihood of accurate communica-tion. We discuss how our models correspond to experimentalobservations and see what predictions are made for future ex-periments.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"phonetics; game theory; communication games; clear speech; Lombard effect"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6rc4k1wm","frozenauthors":[{"first_name":"Paul","middle_name":"","last_name":"Tupper","name_suffix":"","institution":"Simon Fraser University","department":""},{"first_name":"Jie","middle_name":"","last_name":"Jian","name_suffix":"","institution":"Simon Fraser University","department":""},{"first_name":"Keith","middle_name":"","last_name":"Leung","name_suffix":"","institution":"Simon Fraser University","department":""},{"first_name":"Yue","middle_name":"","last_name":"Wang","name_suffix":"","institution":"Simon Fraser University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27903/galley/17541/download/"}]}
