Morphological personalization of a physiological articulatory model

A physiological articulatory model is capable of simulating movements of the articulatory organs together with their morphology, without limitation of the observation approaches and ethics. The model can be a tool for investigating an aspect of individual characteristics of speech, if it is adjusted to the form a particular speaker´s organs. This study reports our effort to personalize an articulatory model to multiple speakers. To do so, we propose a method for constructing personalized articulatory models based on the adaptation of a prototype model by transformation. Accordingly, new models were built for three speakers, which successfully reflected their morphological features. Also, the models were found to be able to simulate typical tongue movements in the same way as the prototype model performed.
