Gestural Cohesion and Timing in Speech Production

How to negotiate the tension between the cognitive and physical properties of speech has been a central issue in linguistics for many decades and much recent influential research is built on the insight that phonology and phonetics inform each other (e.g., Boersma 1998; Pierrehumbert 2000; Prince & Smolensky 2004). The framework of articulatory phonology has also gained recognition as a model of grammar which argues that the spatiotemporal coordination of speech events is an integral part of phonological representation. This model claims that important insights into the nature of linguistic units and the speech production process can be gained under the assumption that these are grounded in the coordination of linguistically significant vocal tract events, so-called gestures (Browman & Goldstein 1990; Fowler et al. 1980). This theoretical framework explicitly models the temporal coordination of speech events and thus allows us to formulate and empirically test hypotheses about the relation of the observable, physical principles of speech to cognitive representations.
The current project investigates speech errors and the organization of sounds into syllables, aiming for a new understanding of the relation between abstract phonological planning and the physical implementation of speech. The questions addressed here speak to the much debated issue whether regularities occurring when individual sounds combine, erroneously in slips of the tongue and non-errorfully in syllabic organization, can adequately be captured as manipulation of linear sequences of symbolic units. Doubt has been cast on the long-standing assumption of symbolic segments particularly through the increasing availability of articulatory records of speech. These suggest for instance that speech errors attributed to categorical segmental replacements may in fact be gradient intrusions of articulatory gestures. Traditionally it has been assumed that the units of speech production are symbolic segments consisting of atemporal phonological feature bundles which are mapped onto dynamic specifications only when the encoded phonological structure is about to be uttered. Evidence for this view has come, among others, from the combinatorial properties of segments: The errorful combination of sounds in speech errors has long been understood to be a serial misordering in a linear string of symbolic segments. Also the combination of sounds into onset, nucleus and coda has traditionally been described on the basis of a linear string of segments, governed by the syllable hierarchy, although the empirical status of the segment has never been uncontroversial. The current project uses speech errors and syllabic organization to test the hypothesis that, at least in some cases, these phenomena may reflect complex molecular constellations comprised of articulatory gestures, and do not necessarily implicate abstract symbolic structures.
