Inverse Modeling of Biomechanical Tongue Control : From Articulation Data to Muscle Activation

Abstract: We map real articulation data for five Swedish phonemen sequences onto parameters of a biomechanical tongue model that produces movement and muscle activations from position data. The movement produced is broadly correct and could likely be improved by a more fine tuned mapping. The muscle activations were found to vary between simulations using the same data but matched well with previous studies on muscle activity for vowels.
