Abstract :
In this paper, we present an improved method for decomposing the speech signal into the harmonic and the noise parts. The improvements make the method more accurate and robust by including a new pitch detection algorithm. In separating the noise and the harmonic components, this improved harmonic-plus-noise (H+N) decomposition method uses a weighted least-squares method aiming at maximizing the harmonic part. Tests show that the method performs reliably and robustly
