This article describes a F0 curve estimation scheme based on a B-spline model. We compare this model with more classical spline representation. The free parameters of both models are the number of knots and their location. An optimal location is proposed using a simulated annealing strategy. Experiments on real F0 curves confirm the adequacy and good performance of the B-spline approach, estimated via the least-square error criterion.
