“…First, as described above, reaction times were measured from the acoustic signal. The onset of movement of speech organs precedes the acoustic onset of speech to different degrees depending on the manner of the initial segment (Mooshammer et al 2012). The onset of acoustic energy for target words that begin with voiceless stops, such as pipette and caress, does not occur until the release of the consonant.…”

This study employs a stress priming paradigm to investigate sensitivity to metrical structure in speech planning and production in Australian English. Target words with iambic stress were preceded by primes with either congruent or incongruent stress and also embedded in metrical contexts biased towards either persistent foot types (Experiment 1) or variable foot types (Experiment 2). Both naming latency, the time from stimulus presentation to the onset of speech, and phonetic patterns showed sensitivity to metrical manipulations. The paradigm produced stress errors, iambic targets produced as trochees, and variation in vowel formants and syllable duration as a function of metrical context. Patterns in the reaction time data indicated sensitivity to global metrical biases calculated over feet. When the metrical bias was toward persistent feet, iambs were produced more quickly in the congruent stress context. When the metrical bias was reversed, iambs were produced more quickly in the incongruent stress context. This pattern of results supports a speech production model that represents metrical structure and allows competition at the metrical level to influence phonetic variability.

“…Part of this effect is due to competition in retrieval: more frequent syllables and more phonotactically probable segmental sequences are initiated more rapidly [45]–[47]. Reaction times based on articulatory movement initiation in a prepared response paradigm have been reported to be approximately 180 ms for stop-initial CV syllables [48]. Crucially, that study controlled pre-response articulatory posture to prevent speakers from configuring their vocal tract to facilitate rapid reaction time, which [49] found to be a common strategy.…”

Studies of the control of complex sequential movements have dissociated two aspects of movement planning: control over the sequential selection of movement plans, and control over the precise timing of movement execution. This distinction is particularly relevant in the production of speech: utterances contain sequentially ordered words and syllables, but articulatory movements are often executed in a non-sequential, overlapping manner with precisely coordinated relative timing. This study presents a hybrid dynamical model in which competitive activation controls selection of movement plans and coupled oscillatory systems govern coordination. The model departs from previous approaches by ascribing an important role to competitive selection of articulatory plans within a syllable. Numerical simulations show that the model reproduces a variety of speech production phenomena, such as effects of preparation and utterance composition on reaction time, and asymmetries in patterns of articulatory timing associated with onsets and codas. The model furthermore provides a unified understanding of a diverse group of phonetic and phonological phenomena which have not previously been related.

“…Speech motor plans are assumed to incorporate a speaker's implicit “knowledge” of the language-specific regularities of speech motor patterns that is established during speech acquisition [59]. Accordingly, the stability of acquired speech motor plans depends on the frequency of occurrence of the respective motor patterns in a speaker's language [60].…”

In less than three decades, the concept “cerebellar neurocognition” has evolved from a mere afterthought to an entirely new and multifaceted area of neuroscientific research. A close interplay between three main strands of contemporary neuroscience induced a substantial modification of the traditional view of the cerebellum as a mere coordinator of autonomic and somatic motor functions. Indeed, the wealth of current evidence derived from detailed neuroanatomical investigations, functional neuroimaging studies with healthy subjects and patients and in-depth neuropsychological assessment of patients with cerebellar disorders shows that the cerebellum has a cardinal role to play in affective regulation, cognitive processing, and linguistic function. Although considerable progress has been made in models of cerebellar function, controversy remains regarding the exact role of the “linguistic cerebellum” in a broad variety of nonmotor language processes. This consensus paper brings together a range of different viewpoints and opinions regarding the contribution of the cerebellum to language function. Recent developments and insights in the nonmotor modulatory role of the cerebellum in language and some related disorders will be discussed. The role of the cerebellum in speech and language perception, in motor speech planning including apraxia of speech, in verbal working memory, in phonological and semantic verbal fluency, in syntax processing, in the dynamics of language production, in reading and in writing will be addressed. In addition, the functional topography of the linguistic cerebellum and the contribution of the deep nuclei to linguistic function will be briefly discussed. As such, a framework for debate and discussion will be offered in this consensus paper.
