Description: CELP
The most common Speech coding scheme is Code-Excited Linear Predictive (CELP) coding, which is used for example in the GSM standard. In CELP, the modelling is divided in two stages, a linear predictive stage that models the spectral envelope and code-book based model of the residual of the linear predictive model.

-Voice synthesis program source! psalo frequency domain pitch synchronous superposition method. It was first carried out on the original speech signal a short-time frequency-domain transform, to the short-time spectrum and short-time spectrum envelope. The short-time spectrum divided by the short-time spectrum envelope of the short time spectrum of the sound source, the short time spectrum of the real part of the sound source, and the imaginary parts of the linear interpolation, can achieve the purpose of changing the fundamental frequency of the alternating speech signal, and then then the inverse transform of the frequency domain, can be to the short-time speech signal after conversion. The short-time spectral envelope section can be varied independently, in order to achieve the purpose of changing the tone. Platform: |

Description: Although it has
been proven to be particularly effective in many applications,EMD
method has several drawbacks. The major problem with EMD is
the lack of theoretical Framework which leads to difficulties for
the characterization and evaluation this approach. On top of the
mathematical model, there are other concerns with mode mixing
and transient phenomena, such as intermittency or pure tones separation.
This paper follows a previous published nonlinear diffusion-
based filtering to solve the mean-envelope estimation in sifting
process. The major improvements made in this present work are a
non-iterative resolution scheme for the previously proposed partial
differential equation (PDE), a new definition of the stopping function
used in the PDE framework, and finally an automatic regularization
process based on inverse problem theory to deal with mode
mixing or transient detection problem. Obtained Platform: |
