“…Combined with the fact that biological systems are naturally more sensitive to contrast (Kluender & Kiefte, 2006), it was predicted that processing in the left hemisphere would induce stronger contrastive effects on vowel targets than processing in the right hemisphere. This hypothesis offered a possible explanation for earlier demonstrations of variation in the strength and direction of context effects on vowel perception (Aravamudhan et al, 2008;Mitterer, 2006;Sjerps et al, 2011a;Wade & Holt, 2005;Watkins, 1991). We indeed observed an influence of laterality on the strength of context effects, but the influence was in the opposite direction from that predicted by AST.…”

“…For instance, Watkins (1991) found no effect of contralaterally presented noise contexts on the perception of speech targets, but speech analogs of these stimuli did elicit contrastive effects. Moreover, integrative effects have been reported in the spectral domain (Aravamudhan, Lotto, & Hawks, 2008;Mitterer, 2006) and with respect to durational distinctions (Fowler, 1992;van Dommelen, 1999). These inconsistencies between contrastive and integrative effects could reflect differences in the relative involvement of the two hemispheres with speech and non-speech stimuli.…”

a b s t r a c tListeners perceive speech sounds relative to context. Contextual influences might differ over hemispheres if different types of auditory processing are lateralized. Hemispheric differences in contextual influences on vowel perception were investigated by presenting speech targets and both speech and non-speech contexts to listeners' right or left ears (contexts and targets either to the same or to opposite ears). Listeners performed a discrimination task. Vowel perception was influenced by acoustic properties of the context signals. The strength of this influence depended on laterality of target presentation, and on the speech/non-speech status of the context signal. We conclude that contrastive contextual influences on vowel perception are stronger when targets are processed predominately by the right hemisphere. In the left hemisphere, contrastive effects are smaller and largely restricted to speech contexts.

“…Interestingly, however, this context effect was observed only when the stimuli contained strong velar tokens on the extreme end of the labial-velar continuum, which is quite unusual for context effects in speech perception. In the literature on context effects in speech perception (see, e.g., Beddor, Harnsberger, & Lindemann, 2002;Fowler, Brown, & Mann, 2000;Kingston, Kawahara, Chambless, Mash, & Brenner-Alsop, 2009;Lotto & Kluender, 1998;Mann, 1980;Mitterer, 2006aMitterer, , 2006bSmits, 2001), stronger context effects have been observed when the stimuli are more ambiguous, generally falling on the middle of the continuum. The opposite was observed here in the present study, with the context effect arising with the least ambiguous stimulus at the end of the labial-to-velar continuum.…”

In connected speech, phonological assimilation to neighboring words can lead to pronunciation variants (e.g., 'garden bench'→ "gardem bench"). A large body of literature suggests that listeners use the phonetic context to reconstruct the intended word for assimilation types that often lead to incomplete assimilations (e.g., a pronunciation of "garden" that carries cues for both a labial [m] and an alveolar [n]). In the current paper, we show that a similar context effect is observed for an assimilation that is often complete, Korean labial-to-velar place assimilation. In contrast to the context effects for partial assimilations, however, the context effects seem to rely completely on listeners' experience with the assimilation pattern in their native language

Two experiments examined how Dutch listeners deal with the effects of connected-speech processes, specifically those arising from word-final /t/ reduction (e.g., whether Dutch [tas] is tas, bag, or a reduced-/t/ version of tast, touch). Eye movements of Dutch participants were tracked as they looked at arrays containing 4 printed words, each associated with a geometrical shape. Minimal pairs (e.g., tas/tast) were either both above (boven) or both next to (naast) different shapes. Spoken instructions (e.g., "Klik op het woordje tas boven de ster," [Click on the word bag above the star]) thus became unambiguous only on their final words. Prior to disambiguation, listeners' fixations were drawn to /t/-final words more when boven than when naast followed the ambiguous sequences. This behavior reflects Dutch speechproduction data: /t/ is reduced more before /b/ than before /n/. We thus argue that probabilistic knowledge about the effect of following context in speech production is used prelexically in perception to help resolve lexical ambiguities caused by continuous-speech processes.Keywords: spoken-word recognition, continuous-speech processes, /t/-reduction, eye tracking, DutchContinuous speech is peppered with noncanonical pronunciations of words. Continuous-speech processes, such as assimilation, reduction, and deletion, operate during speech production and can substantially change the way words are realized. For example, a speaker of British English may say [waImbɔʔ1] in a casual request for a wine bottle, but say [waIn] and [bɔtəl] when asked how these words should be pronounced. It is the listener's task to recognize spoken words in spite of this variability. A particularly acute problem is when a continuous-speech process creates a lexical ambiguity. We examine that situation here, focusing on the effects of word-final /t/ reduction. If a speaker does not clearly pronounce the final [t] of duct, for example, how does the listener work out that they are not talking about a duck?Two answers to this question have been proposed. The first is based on lexical storage. There are in fact three radically different versions of this view. Lahiri and Marslen-Wilson (1991) and Lahiri and Reetz (2002) proposed a model of the mental lexicon in which entries are highly abstract and phonologically underspecified. A lexical entry for a given word only includes the phonological features that are reliably associated with tokens of that word. For instance, the alveolar nasal consonants in English are assumed to be specified only as nasal, with no specification of place of articulation, which may vary due to phonological assimilation. The token [waIm] can be recognized as an instance of the word wine because there is no mismatch between the last nasal segment [m] in the input and the lexical representation for this segment. Similarly, lexical entries may be underspecified for the presence of a word-final /t/. The input [d∧k] would thus match a stored lexical representation corresponding to duct. The second lexical-storage a...
