Computationally, motor objects are arranged class-wise on an inheritance basis , thus capturing relationship generalisations between them. In articulatory phonology terms gestures as represented in the gestural score characterise the prior planning of motor objects. They too lend themselves to computational modelling using the object oriented paradigm. In this paper I have discussed how computational modelling in speech production is not a novel concept and that it exists distinctly from the requirements of modelling for speech technology. However, the fact that computational modelling is possible and that it is pursued by researchers concerned with being maximally explicit does not guarantee that it is computationally adequate.
Computational adequacy occurs when a computational model achieves certain criteria.
In these latter requirements the combination of articulatory phonology and task dynamics falls short of true computational adequacy. It would not be difficult, however, to arrange for these requirements to be met. For all that the proponents recognise the fundamental difference between planning and execution, and for all that they seek to unify respectively phonology and phonetics their graphically based model and my object oriented computational version do not in the end do anything but provide a very rickety bridge between the two. We should at least be pleased that it now has the potential to lag behind none of them. Phonology Yearbook 3 .
