F0 contour estimation using ELS-based robust time-varying complex speech analysis

Robust F₀ (Fundamental frequency) estimation plays an important role in speech processing. This paper proposes simple F₀ contour estimation algorithm based on the robust TV-CAR speech analysis, in which the F₀ contour is estimated by peak-picking for the estimated time-varying spectrum by means of ELS-based robust complex speech analysis for an analytic speech signal. The experimental results demonstrate that the proposed method leads to more accurate continuous F₀ estimation than the conventional ones for high-pitched speech.
