We describe a method for adapting a physical vocal tract model's anatomical and gestural parameters using acoustic information to match a target speaker. Physical vocal tract models are hard to adjust to match a speaker, as doing so requires information which is difficult to capture, such as X-Ray or MRI information. We propose an analysis-by-synthesis(More)
