“…Whereas in the PDP models of Jordan (1990) and Dell and colleagues (Dell et al, 1993), articulation is by design initiated when the features of the first segment have become activated, adopting articulatory buffering would seem to be compatible with NST, although Santiago et al (2000) explicitly argued against it. Articulation may then be initiated when the buffer contains a phonological word or more rather than the initial segment or syllable.…”

Minimalist theories of spoken language planning hold that articulation starts when the first speech segment has been planned, whereas non-minimalist theories assume larger units (e.g., Levelt, Roelofs, & Meyer, 1999a). Three experiments are reported, which were designed to distinguish between these views using a newhybrid task that factorially manipulated preparation and auditory priming of spoken language production. Minimalist theories predict no effect from priming of non-initial segments when the initial segment of an utterance is already prepared; observing such a priming effect would support non-minimalist theories. In all three experiments, preparation and priming yielded main effects, and together their effects were additive. Preparation of initial segments does not eliminate priming effects for later segments. These results challenge the minimalist view. The findings are simulated by WEAVER++ (Roelofs, 1997b), which employs the phonological word as the lower limit for articulation initiation

“…For example, MacKay's (1987;Santiago et al, 2000) NST assumes that words are planned via a tree traversal process that operates in a sequential top-down and leftto-right fashion. The initial syllable of a word is planned before its non-initial syllables, and within a syllable initial segments are planned before non-initial segments.…”

“…Furthermore, the fact that words with more syllables have longer speech onset latencies than words with fewer syllables when other factors, such as number of segments or word frequency are controlled for does not pose a problem for this proposal. These effects of word length can be explained by assuming that the phonological rather than the phonetic encoding of a phonological word must be completed before speech onset (see Eriksen, Pollack, & Montague, 1970;Klapp, Anderson, & Berrian, 1973;Meyer et al, 2003;Santiago, MacKay, Palma, & Rho, 2000, but see also Roelofs, 2002;Santiago, MacKay, & Palma, 2002;Wheeldon & Lahiri, 1997). Further research is needed to investigate which planning unit is used in a given speech context and what factors release the articulation initiation.…”

Effects of syllable frequency in speech production

In the speech production model proposed by [Levelt, W. J. M., Roelofs, A., Meyer, A. S. (1999). A theory of lexical access in speech production. Behavioral and Brain Sciences, 22, pp. 1-75.], syllables play a crucial role at the interface of phonological and phonetic encoding. At this interface, abstract phonological syllables are translated into phonetic syllables. It is assumed that this translation process is mediated by a so-called Mental Syllabary. Rather than constructing the motor programs for each syllable on-line, the mental syllabary is hypothesized to provide pre-compiled gestural scores for the articulators. In order to find evidence for such a repository, we investigated syllable-frequency effects: If the mental syllabary consists of retrievable representations corresponding to syllables, then the retrieval process should be sensitive to frequency differences. In a series of experiments using a symbol-position association learning task, we tested whether highfrequency syllables are retrieved and produced faster compared to low-frequency syllables. We found significant syllable frequency effects with monosyllabic pseudo-words and disyllabic pseudo-words in which the first syllable bore the frequency manipulation; no effect was found when the frequency manipulation was on the second syllable. The implications of these results for the theory of word form encoding at the interface of phonological and phonetic encoding; especially with respect to the access mechanisms to the mental syllabary in the speech production model by (Levelt et al.) are discussed. q

Santiago, MacKay, Palma, and Rho (2000) report two picture naming experiments examining the role of syllable onset complexity and number of syllables in spoken word production. Experiment 1 showed that naming latencies are longer for words with two syllables (e.g., demon) than one syllable (e.g., duck), and longer for words beginning with a consonant cluster (e.g., drill) than a single consonant (e.g., duck). Experiment 2 replicated these ndings and showed that the complexity of the syllable nucleus and coda has no effect. These results are taken to support MacKay's (1987) Node Structure theory and to refute models such as WEAVER ‡ ‡ (Roelofs, 1997a) that predict effects of word length but not of onset complexity and number of syllables per se. In this comment, I show that a re-analysis of the data of Santiago et al. that takes word length into account leads to the opposite conclusion. The observed effects of onset complexity and number of syllables appear to be length effects, supporting WEAVER ‡ ‡ and contradicting the Node Structure theory.Theories of spoken word production differ in their claims about the role of syllables and their internal structure. Santiago, MacKay, Palma, and Rho (2000) contrasted the predictions of two types of theory. According to MacKay's (1987) Node Structure theory, henceforth NST, syllables and their internal structure are planned via a tree traversal process that operates in a top-down and left-to-right fashion. In particular, the initial syllable of a word is planned before its non-initial syllables, and syllable Requests for reprints should be addressed to Ardi Roelofs,
