Abstract
In this contribution, we present HNS, a new analysis/modification/ synthesis model based on a harmonic + noise representation of the speech signal. Significant improvements over previous work on the subject are proposed at both the analysis and the synthesis stages: 1) A model of harmonically related sinusoids with linearly varying complex amplitudes for the representation of the deterministic part of the signal. 2) A joint time-domain and frequency-domain representation of the stochastic part of the signal. 3) A pitch-synchronous PSOLA-like synthesis scheme. Informal listening-tests demonstrate the effectiveness of this approach for time-scale modifications.Keywords
