Are context effects in speech perception modulated by visual information?
Joseph D. Stephens & Lori L. Holt Poster available in PDF format An important goal in speech perception research is to understand the means by which the perception of speech sounds is influenced by surrounding context. Fowler, Brown, & Mann (2000) reported a shift in perception of a consonant-vowel syllable as a function of visual speech information accompanying a preceding syllable. That finding was interpreted as contradictory to a general auditory account of such context effects (e.g., Lotto & Kluender, 1998). The present study attempted to replicate that finding. Replication was only possible using the stimulus materials of the original study, and data from a modification of the original experiment suggest the effect may have been caused by unintended variation in the visual tracks of the original stimuli. Results will be described in terms of a general perceptual account of context effects in speech perception. ————– top | Research ————– 14th Annual Beckman Front
