Implicit Learning Leads to Familiarity Effects for Intonation but not for Voice

Previous studies have shown that speech processing is accelerated for familiar voices in contrast to unfamiliar ones, and for familiar intonation in contrast to unfamiliar intonation. The present experiments probed these effects in a single experiment and tested whether they also occur with short, implicit familiarization. Results of two auditory lexical decision tasks (Experiment 1 with a task-based familiarization phase and Experiment 2 with a passive listening familiarization phase), showed that familiarity with the intonation (rise vs. fall) affected reaction times but that familiarity with the voice (speaker A vs. B) did not. Our results suggest that intonation (which contributes to utterance interpretation) is stored in the mental lexicon, but voice information is not.
