New model for speech residual signal shaping with static nonlinearity
نویسندگان
چکیده
In this paper we apply a nonlinear Hammerstein model for speech analysis and coding using frame-based parameter solving. This paper presents a method for calculating the adaptive frame-based coefficients for a Hammerstein model by modifying the residual signal to the desired form. The method is such that the nonlinear and linear coefficients can be obtained without iterations. In experiments the residual information was reduced significantly by using proper nonlinearities and residual shaping in the preprocessing phase.

Signal subspace approach for psychoacoustically motivated speech enhancement
In this paper we deal with the perceptually motivated signal subspace methods for speech enhancement. We focus on extended spectral-domain-constrained (SDC) estimator. It is obtained using Lagrange multipliers method. We present an algorithm for a precise computation of the Lagrange multipliers, allowing for a direct shaping the residual noise power spectrum. In addition the SDC estimator is pr...
متن کاملUniform concatenative excitation model for synthesising speech without voiced/unvoiced classification
In general, speech synthesis using the source-filter model of speech production requires the classification of speech into two classes (voiced and unvoiced) which is prone to errors. For voiced speech, the input of the synthesis filter is an approximately periodic excitation, whereas it is a noise signal for unvoiced. This paper proposes an excitation model which can be used to synthesise both ...
متن کاملHammerstein Model for Speech Coding
A nonlinear Hammerstein model is proposed for coding speech signals. Using Tsay’s nonlinearity test, we first show that the great majority of speech frames contain nonlinearities (over 80% in our test data) when using 20-millisecond speech frames. Frame length correlates with the level of nonlinearity: the longer the frames the higher the percentage of nonlinear frames. Motivated by this result...
متن کاملAn approximate solution for perceptually constrained signal subspace speech enhancement method
In this paper we present a low-complexity version of perceptually constrained signal subspace method (PCSS) for speech enhancement. An approximate solution is presented in a new form which provides perceptually optimal residual noise shaping. The proposed approach does not require a whitening transformation and is sub-optimal for coloured noise. A comparative evaluation of selected methods is p...
متن کاملSpeech Enhancement based on
In this paper, we propose a novel approach to speech enhancement, which incorporates a new criterion based on residual noise shaping. In the proposed approach, our goal is to make the residual noise perceptually comfortable although the power of the residual noise is relatively high. In contrast to the conventional techniques, the proposed approach regulates not only the power of the signal dis...
