Abstract

The paper deals with an approach to a smooth and precise fundamental frequency estimator with voiced/unvoiced decision. Our method is based on a parametric Harmonic and Noise Model used especially in speech modification and synthesis. Errors between speech signal and resynthesized ones with different estimations of fundamental frequencies are computed. Dynamic programing is used to retrieve the best path in an "error map". It uses a constant for setting smoothness of the path. Reliable voiced/unvoiced segmentation can be done using thresholding of the error.
