Abstract(in English) | Many algorithms for formant estimation from speech signals are based on the Z transform expresion. However there is a problem; in the transfer function based on this, the value of coefficient of the polynomial is depend on the sampling frequency though the coefficient is invariant in the continuous signal space. It is known that the δtransform can be used for the approximation of the continuous space, but it is very difficult to solve numerically the estimation equation with the ill-condition, and is very high sensitivity for the observation noise. In this paper we propose a new algorithm with a modification of the estimation wquation, and show that our algorithm is useful to solve the above problem. |
