Abstract
We consider enhancement of speech based on a harmonic plus noise representation of the signal. We propose a novel model and its associated estimation procedure for the harmonic component. The model is nonparametric and capable of representing nonstationarity and the estimation approach uses a data-driven method to optimize the duration from which each harmonic component is locally estimated
