TD-PSOLA MATLAB编写语音合成模拟程序(The simulation program of combined speech signal beased on TD-PSOLA MATLAB method)
分段信噪比测试,主要是用于语音增强,语音编码后的测试使用(segment SNR test, primarily for speech enhancement, speech coding after testing)
近场的MUSIC算法,可用于近场噪声源识别(Near-field MUSIC algorithm can be used for near-field noise source identification)
语音信号的时域频域分析,从短时能量到语谱图,以及线性预测参数和梅尔倒谱系数等等(Speech signal in time domain frequency domain analysis, from the short-term energy to the spectrogram, and the linear prediction parameters and the Mel cepstral coefficients, etc.)
功率倒置算法的LMS实现,因为自己遇到了点问题,本人一直在找这个程序,没找到,故自己重新检查把问题发现了,相信如果你要实现的话可能会遇到这个问题祝你好运!(Power inversion algorithm LMS implementation, because they encountered a point problem, I ve been looking for this program, did not find it to re-examine the problem yourself discovered, I believe if you want to achieve, then you may encounter this problem Good luck!)
图像识别,可以识别出图片中的需要的水果。mtalab实现的。(Image recognition, the image can be identified in fruit required. mtalab achieved.)
本文介绍MVDR算法实现及其改进 用于多麦克风语音增强(The minimum variance distortionless response (MVDR), originally developed by Capon for frequency-wavenumber analysis, is a very well established method in array process-ing. It is also used in spectral estimation. The aim of this paper is to show how the MVDR method can be used to es-timate the magnitude squared coherence (MSC) function, which is very useful in so many applications but so few methods exist to estimate it)
这 里主要对LMS算法及一些改进的LMS算法(NLMS算法、变步长LMS算法、变换域LMS算法)之间的不同点进行了比较,在传统的LMS算法的基础上发 展了LMS算法的应用。另一方面又从RLS算法的分析中对其与LMS算法的不同特性进行了比较。(Here mainly on the LMS algorithm and some improvements of the LMS algorithm (NLMS algorithm, variable step size LMS algorithm, transform domain LMS algorithm) between the different points of comparison, in the traditional LMS algorithm developed on the basis of the application of the LMS algorithm. On the other hand from the analysis of RLS algorithm and LMS algorithm for its different characteristics compared.)
