摘要：
In this paper we present the properties of a parametric speech model based on a deterministic plus noise representation of speech initially suggested by Laroche et al. [1]. Aiming at a high resolution analysis of speech signals for voice quality control (transformation) and assessment, we focus on the deterministic representation and we reveal the properties of the model showing that such a representation is equivalent to a time-varying quasi-harmonic representation of speech. Results show that the model is appropriate in estimating accurately linear amplitude modulations and modeling the inharmonicity of speech.
