Abstract

This study aimed to address whether phonetic convergence (speech imitation) and auditory imagery in reading are fundamentally governed by the same process — episodic encoding (c.f., Goldinger, 1998). A set of participants (talkers; N = 12) were recorded speaking sentences at a baseline level. Talkers were then exposed model speaker with either a fast or slow speech rate and then engaged in a reading phase where they read sentences thought to be written by that speaker. If episodic encoding predicts effects of phonetic convergence and auditory imagery in reading style, then talkers should be influenced by a speaker on three dimensions: pronunciation of words, duration of words, and duration of sentences. A different set of participants (raters; N = 68) engaged in an AXB perceptual similarity ratings task. Raters were presented with three sets of recordings of individual target words in a row — A (baseline), X (model), and B (reading) — and made perceptual similarity ratings, indicating whether A or B is more similar in pronunciation to X . If episodic encoding predicts effects of phonetic convergence then talkers should be rated as being perceptually similar to the speaker. The results of the study suggest that episodic may not play a role in either phonetic convergence or auditory imagery and speech.
