A background for sinusoid based representation of voiced speech

Description	Author affiliation: CAPS, Lisboa Codex, Portugal (Marques, J.)
Abstract	Sinusoid based models have been used in the last few years for high quality representation of voiced speech. In this paper we first review a theoretical basis for this kind of representation, and then introduce a spectral model for varying-frequency sinusoids. This model is used for estimating the sinusoid parameters end it is also intended for accurate representation of the spectrum of voiced speech. A time warping procedure is presented, which permits to reduce the overlap between high frequency spectral lines, with the purpose of improving their estimation.
