Extrinsic talker normalization alters self perception during speech

Abstract

In this study, we investigated the effects of changes in formant structure of externally presented speech signals on participants’ auditory perception of their own speech output (i.e., feedback) during a word production task. The study involved a novel combination of two previously established research paradigms: (1) sensorimotor adaptation to altered auditory feedback during speech, and (2) extrinsic talker normalization of vowel perception through the presentation of carrier-phrases spoken with different formant patterns. The results suggest that the formant frequencies of a carrier-phrase presented immediately prior to word production serve as a frame of reference for the perception of selfgenerated speech outcomes, thereby influencing subsequent speech targets. This finding extends other recent evidence indicating that the auditory processing of speech sounds guiding speech production is highly flexible and adaptive under a range of different conditions.
