Abstract
The present study investigates the informativity of anticipatory coarticulatory acoustic detail about inflectional suffixes in English verbs, performing two experiments in which listeners classified inflectional functions of verbs. Listener response latencies were slower when acoustic detail resulting from anticipatory coarticulation mismatched with the inflectional suffix. The results indicate that listeners actively use coarticulatory phonetic detail to predict the verbs' inflectional function.
Highlights
From a discriminative learning perspective (Ramscar et al, 2010; Ramscar et al, 2013), listeners use acoustic cues to predict three types of outcomes during comprehension

Summary
From a discriminative learning perspective (Ramscar et al, 2010; Ramscar et al, 2013), listeners use acoustic cues to predict three types of outcomes during comprehension. Our aim is to investigate the degree to which acoustic detail associated with anticipatory coarticulation is informative about changes in meaning, meaning at the level of inflectional functions of English verbs. This is accomplished with two splicing experiments in which listeners classify (a) bare verbal stems and (b) original inflected verbs and inflected verbs where the inflectional suffix is spliced to an uninflected stem. We discuss systematic variation in acoustic cues and what systematic variation has been identified as informative about phonetic contrasts From this we derive our hypothesis that coarticulatory phonetic detail provides informative cues about inflectional outcomes in inflected verbs
