Ultrasound imaging has long been used as a non-invasive means of studying tongue movement in real time, producing data which are useful for speech production research; orthophony and language learning; preservation of rare singing cultural heritage; and silent speech interface applications. All these applications would benefit from the ability to associate a parameterized tongue model to physical tongue movement in real time – a tongue avatar – however, the poor quality and difficulty of interpretation of ultrasound images has hampered progress along these lines. The talk will introduce a project underway at Tianjin University and Pierre and Marie Curie University in Paris, France, to associate a generic constraint-driven FEM of the tongue to real time ultrasound images of the tongue. After introducing the applications, some underlying principles, current progress, remaining difficulties, and future plans will be presented.
