“…Work by Schroeder and colleagues examining recordings of macaque monkey ( Macaca mulatta and M. fascicularis ) auditory association cortices, when subjects were presented with auditory and somatosensory input, suggest a significant temporal overlap between the two, as well as integration at an early stage of auditory cortical processing ( Schroeder et al, 2001 ). Wang and colleagues investigated the simultaneous influence of auditory and vibrotactile feedback disturbances in f 0 control in human subjects, finding stronger compensatory responses in participants in a combined vibrotactile-auditory stimuli condition than for either single modality on its own ( Wang et al, 2015a , b ; see also Larson et al, 2008 ).…”

Every normally developing human infant solves the difficult problem of mapping their native-language phonology, but the neural mechanisms underpinning this behavior remain poorly understood. Here, motor constellation theory, an integrative neurophonological model, is presented, with the goal of explicating this issue. It is assumed that infants’ motor-auditory phonological mapping takes place through infants’ orosensory “reaching” for phonological elements observed in the language-specific ambient phonology, via reference to kinesthetic feedback from motor systems (e.g., articulators), and auditory feedback from resulting speech and speech-like sounds. Attempts are regulated by basal ganglion–cerebellar speech neural circuitry, and successful attempts at reproduction are enforced through dopaminergic signaling. Early in life, the pace of anatomical development constrains mapping such that complete language-specific phonological mapping is prohibited by infants’ undeveloped supralaryngeal vocal tract and undescended larynx; constraints gradually dissolve with age, enabling adult phonology. Where appropriate, reference is made to findings from animal and clinical models. Some implications for future modeling and simulation efforts, as well as clinical settings, are also discussed.

“…Vocal folds have been modelled with different degrees of complexity and a lot of work has been dedicated to this field in the literature ( Wang et al, 2012b). The variation in the movement of the tongue, jaw, and lips forms different shapes of the vocal tract.…”

“…Kelly and Lochbaum (1962) were first to present a one-dimensional waveguide model of the vocal tract. Transmission line matrix (Hoefer, 1985;Johns, Beurle, 1971), finitedifference time-domain methods (Karjalainen, 2003;Välimäki et al, 2006;Wang et al, 2012a;2012b), real-time waveguide model (Mathur et al, 2006), and wave digital filters (Fettweis, 1971) were developed in accordance with the idea of Kelly-Lochbaum model (Kelly, Lochbaum, 1962). An extension of a one-dimensional digital waveguide (digital waveguide model) was first introduced by Smith (1985;1992) and Van Duyne, Smith (1993a;1993b), and is being used in the modelling of the vocal tract (Cooper et al, 2006;Mullen et al, 2003;2007 In their paper, the elongation of any segment is achieved by concatenation of two extra segments.…”

A vocal tract model based on a digital waveguide is presented in which the vocal tract has been decomposed into uniform cylindrical segments of variable lengths. We present a model for the real-time numerical solution of the digital waveguide equations in a uniform tube with the temporally varying cross section. In the current work, the uniform cylindrical segments of the vocal tract may have their different lengths, the time taken by the sound wave to propagate through a cylindrical segment in an axial direction may not be an integer multiple of each other. In such a case, the delay in an axial direction is necessarily a fractional delay. For the approximation of fractional-delay filters, Lagrange interpolation is used in the current model. Variable length of the individual segment of the vocal tract enables the model to produce realistic results. These results are validated with accurate benchmark model. The proposed model has been devised to elongate or shorten any arbitrary cylindrical segment by a suitable scaling factor. This model has a single algorithm and there is no need to make section of segments for elongation or shortening of the intermediate segments. The proposed model is about 23% more efficient than the previous model.
