Theories of Automaticity and Their Relation to Speech Production Models

This paper tests whether lemma frequency impacts the duration of homographic noun–verb homophones in spontaneous speech, e.g. cut (n)/cut (v). In earlier research on effects of lemma frequency (e.g. Gahl 2008), these pairs of words were not investigated due to a focus on heterographic homophones. Theories of the mental lexicon in both linguistics and psycholinguistics differ as to whether these word pairs are assumed to have shared or separate lexical representations. An empirical analysis based on spontaneous speech from the Buckeye corpus (Pitt et al. 2007) yields the result that differences in lemma frequency affect the duration of the N/V pairs under investigation. First, this finding provides evidence for N/V pairs having separate representations and thus supports models of the mental lexicon in which lexical entries are specified for word class. Second, the result is at odds with an account of ‘full inheritance’ of frequency across homophones and consequently with speech production models implementing inheritance effects via a shared form representation for homophonous words. The findings are best accounted for in a model that assumes completely separate lexical representations for homophonous words.

Selection Mechanisms

Naming a picture is slower in categorically related compared with unrelated contexts, an effect termed semantic interference. This effect has informed the development of all contemporary models of lexical access in speech production. However, category members typically share visual features, so semantic interference might in part reflect this confound. Surprisingly, little work has addressed this issue, and the relative absence of evidence for visual form interference has been proposed to be problematic for production models implementing competitive lexical selection mechanisms. In a series of five experiments using two different naming paradigms, we demonstrate a reliable visual form interference effect in the absence of a category relation and show the effect is more likely to originate during lexical or later response selection than during perceptual/conceptual processing. We conclude visual form interference in naming is a significant complicating factor for studies of semantic interference effects and discuss the implications for current accounts of lexical access in spoken word production.

3C Model

This chapter presents the outline of a model of speech-production planning, based on symbolic phonology and the specification of surface-timing patterns using general-purpose timekeeping mechanisms. This phonology-extrinsic-timing-based, three-component (XT/3C) model includes a Phonological Planning Component, to set and prioritize the goals for an utterance; a Phonetic Planning Component, to quantitatively specify the acoustic targets and the movements to achieve them; and a Motor-Sensory Implementation component, to track the planned movements and adjust them to ensure that the targets are reached on time. This approach addresses some of the gaps in earlier speech-production models based on abstract symbolic phonology, by proposing a mechanism for the specification of context-appropriate surface phonetic variation, including timing. In this way it provides an alternative to the Task-Dynamics-based approach embodied in Articulatory Phonology.
