Articulatory synthesis is a technique typically used for speech synthesis, but I think it's an idea that can be more generalized. Essentially there are two parts: the synthesizer, with many many inputs of control, and the control system, designed to manage these inputs of control in a high level intuitive way.
@patchlore Indeed ... there are some interesting algorithms that exploit that phenomenon. For example, https://cogsci.se/soundgen.html
