Seeing is perceiving: Multimodel perception and production of English /r/
supervised by Ioana Chitoran et Emmanuel Ferragne

Summary: This thesis investigates the role of the lips in the perception and production of /r/ in English. Articulatory variation is well-documented in approximant realisations of /r/ in rhotic varieties of English, which present a diverse array of tongue shapes. However, the production of /r/ remains enigmatic, especially concerning non-rhotic Englishes and the contribution of the accompanying labial gesture. The lips are particularly pertinent in Anglo-English /r/ because non-lingual labial articulations are rapidly gaining currency. I argue that the lips enhance the perceptual salience of /r/ in both the auditory and the visual domains. I propose that Anglo-English /r/ has developed a specific lip posture, which I relate to increased exposure to non-lingual variants of /r/ and to the pressure to maintain a perceptual contrast with /w/. Perception data reveal that the visual cue of the lips is more perceptually prominent than the auditory one in the /r-w/ contrast, which may thus motivate the change towards non-lingual labial variants of /r/. This thesis has theoretical implications for the nature of speech perception in general, as well as for the role of visual speech cues in diachronic sound change.
