Resumen
We apply discrete Fourier transforms to musical tempo. Then we perform pitch saliency-based melodyextraction for each frame. Secondly, we use the finite element differential mathematical model for speechtracking with non-fixed parameters. In this paper, the masking threshold of each edge of the speech signal is dynamically determined by introducing a Bayesian tangent shape model. The simulation results showthat the finite element differential mathematical model can remove the noise in the speech signal to a certain extent. Inthe environment of a low signal-to-noise ratio, the advantages of this algorithm over other spectral subtractionmethods are more significant.
