**4.3 Instantiation as schematization**

• **the gestural sub-segmental organization is a topological-neurobiological**

Represented representation is this complex schematization of a mapping model suggesting first the topological mathematical organization of the articulatory/vocal tract organic principle. Beyond the formant principle and its acoustic physical implication, the gestural mode of speech, on the syllable-lexicon level is a topological model of dynamics (morpho-dynamics) that articulates formal representations of speech production/perception in a bidirectional way: what would be the implication of the permutation in a topological space represented by vocal tract/articulatory systems on form and selection events? It supposes a biological/topological interface of both semio/morphogenesis [102]. On the other hand, mental lexicon/mental syllable have been suggested as models of both generative syntax and phonological specification of the syntactic device. From the psycholinguistic point of view [103],

both encoding/computing may enhance the acoustic realization of words.

be a specific module for internal lexicon and syntactic structures. We would henceforth expose a threefold model of instantiation:

tingent continuum and discrete representation/articulation.

• Event structure for lexical—semantic components:

then a referential event of speech biologically instantiated.

• Event structure for lexical-encyclopedic representation:

It entails the activation of a neural image of structure imitating structure and structure imitating the world (anamorphosis and morphosis). Iconicity would then

We distinguish herein between a unitary speech event (or experience) and the complex neural/anatomical network of its processing in a way that activates both semantic and phonological consciousness on a predisposition scheme to link con-

Within the semio-genesis on both continuum/discrete, form/substance levels, the biological instantiation of speech relies likewise the situational basis of an uttering event (enunciation) on the spatial/temporal parameters of representation and articulation. Beyond the phenomenological event of its intentionality, neurobiological instantiation is the set of coordination enabling the co-construction of both articulatory-semantic events of speech [104], from/into structure and from/into

We hypothesize specific neural networks on both motoric/conceptual regions of the brain enabling the computation of a space-time event of speech on gestural/ articulatory levels. It triggers both memory/lexicon sub-events of speech (retrieval, lexical basis for gestures and articulation, Formant calculus and phasing but specifically gestural pointing and targeting). Interaction adjustment parameters enable

• Instantiation as schematization

• Instantiation as functional modularity

Neural schematization has been posited as a theoretical model called Schema theory by Arbib's et al. [106], arguing that this last is the basis for cognitive knowledge or a system of schemata enabling the relation between action and interpretation. Production/perception neural maps are responsible of translating cognitive schemata (or their assemblage) of speech components into sensory-motor images.

## *4.3.1 Neural maps for sequencing*

Copying a phonological—prosodic form onto gestural levels require specific schemas for sequencing, neural maps for copying/deleting or copying/binding enabling both the gestural-phonological interface, the gestural-lexical interface for a determined sequence. It has been proven that mirror neurons form hidden sequences [107] of sensory-motor observed/enacted actions.
