Phonetic recalibration in audiovisual speech

摘要: In 2003, we (Bertelson et al. 2003) reported that phonetic recalibration induced by McGurk-like stimuli can indeed be observed. We termed the phenomenon “recalibration” in analogy with much better known “spatial recalibration,” as considered it a readjustment or fine-tuning of an already existing representation. same year, and complete independence, Norris (2003) very similar they named “perceptual learning speech.” The basic procedure both studies was similar: Listeners were presented phonetically ambiguous speech sound another source contextual information disambiguated sound. our study, listeners halfway between /b/ /d/ context video synchronized face articulated (in short, lip-read information), whereas study (2003), /s/-/f/ heard embedded f- s-biasing word (e.g., “witlo-s/f” f-biasing because “witlof” is Dutch meaning “chicory,” but “witlos” not word). Recalibration (or perceptual learning) subsequently measured auditory-only identification test which participants identified members continuum. manifested itself shift categorization toward contextually defined environment. thus increased their report sounds consistent had received before, so more responses after exposure to rather than /d/, /f/ words /s/-biasing words. Presumably, this reflected adjustment phoneme boundary helped understand prevailing input environment.After these seminal reports, there have been number examined detail (Baart Vroomen 2010a, 2010b; Cutler 2008; Eisner McQueen 2005, 2006; Jesse 2007; Kraljic 2008a, 2008b; Samuel 2006, 2006a, 2006b; Sjerps 2010; Stevens van Linden 2007, Baart 2009a, 2009b; 2004, 2007). what follows, will provide overview literature and, given topic book, focus on audiovisual case.
