In the absence of a theoretical or methodological consensus, different articulatory studies of vowels rely on different measures, which leads to lack of comparability between different sets of results. This paper addresses the problem of how to parametrise the tongue measurements relevant to vowels, obtained from midsagittal articulatory imaging. We focus on the lax vowels subsystem in Northern Anglo-English. A range of measures quantifying tongue position, height and shape are extracted from an ultrasound dataset representing 40 speakers. These measures are compared, based on how well they capture the lingual contrast between different vowels, how stable they are across different speakers, and how intercorrelated they are. The results suggest that different measures are preferred for different vowels, which supports a multi-dimensional approach in quantifying vowel articulation. date: 2025-04-01 date_type: published publisher: SAGE Publications official_url: https://journals.sagepub.com/home/LAS oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2362857 lyricists_name: Nagamine, Takayuki lyricists_id: NTAKA32 actors_name: Nagamine, Takayuki actors_id: NTAKA32 actors_role: owner full_text_status: public publication: Language and Speech issn: 0023-8309 citation: Strycharczuk, Patrycja; Kirkham, Sam; Gorman, Emily; Nagamine, Takayuki; (2025) Dimensionality reduction in lingual articulation of vowels: Evidence from lax vowels in Northern Anglo-English.
