Abstract
A sinusoidal model is presented where the nonstationary nature of speech is considered by using a time-varying frequency and amplitude for each sinusoid. The proposed model generalizes other sinusoidal models while still having an analytically tractable short-time spectrum. The estimation of the parameters of the sinusoids is done in the frequency domain by a suboptimal linear estimator. The experimental results obtained with the proposed model illustrate its ability to represent nonstationary speech frames.<>
