Abstract

An articulatory study of sibilant fricatives is described, with the goal of describing variability in lingual articulation across languages. Real-time Magnetic Resonance Imaging (rtMRI) data were collected from three speakers each of English and Mandarin and two speakers of Serbian. The Chinese and Serbian subjects were born in different parts of China and Serbia respectively and all have some proficiency in English as their second or third language. Data were reconstructed at a rate of 22.4 frames per second using a sliding window technique [1]. Parallel acoustic data were also collected and subsequently denoised [2]. Subjects produced the sibilant fricatives/s/and/ʃ/in symmetrical vowel contexts (eg ‘pa sap’for English and ‘asa’for Mandarin). Articulation was analyzed using a semi-polar grid overlaid on the image plane and midsagittal distance functions were obtained by measuring cross distances at …
