We introduce in this paper an auxiliary function approach to parameter estimation of the constrained sinusoidal model, which enables us to derive a complex-spectrum-domain EM-like multiple F0estimation algorithm. Through simulations, we evaluated the performance of the presented method in the ability to avoid locally optimal solutions. We implemented a monaural speech separation system based on the presented method and confirmed its performance on compound signals of real speech.
