Training to Use Voice Onset Time as a Cue to Talker Identification Induces a Left-Ear/Right-Hemisphere Processing Advantage
Francis, Alexander L.; Driscoll, Courtney
Brain and Language, v98 n3 p310-318 Sep 2006
We examined the effect of perceptual training on a well-established hemispheric asymmetry in speech processing. Eighteen listeners were trained to use a within-category difference in voice onset time (VOT) to cue talker identity. Successful learners (n = 8) showed faster response times for stimuli presented only to the left ear than for those presented only to the right. The development of a left-ear/right-hemisphere advantage for processing a prototypically phonetic cue supports a model of speech perception in which lateralization is driven by functional demands (talker identification vs. phonetic categorization) rather than by acoustic stimulus properties alone.
