Why should speech control studies based on kinematics be considered with caution? insights from a 2d biomechanical model of the tongue.

摘要: A 2D biomechanical model of the tongue is used to simulate movement sequences and speech signals in Vowel-to-Vowel transitions. The analysis focused on how central commands biomechanics can interact influence physical signals. In particular, it shown complex velocity profiles be explained by biomechanics, low-pass filtering effect give an account vocalic reduction phenomenon that observed during production.
