[Speech/Voice recognition/combineVariableNoisySpeechEnhancementAlgorithmPerformance

Description: 语音增强是影响语音识别系统性能的重要成分。为了比较语音增强算法的性能,采用Matlab软件进行了数值仿真,对不同噪声环境下的语音用3种不同的方法进行降噪,采用信噪比、端点检测等方法来降噪效果,并对几种增强算法的性能进行了比较分析。结果表明,在变噪声环境下短时谱MMSE法最佳,谱减法和维纳滤波法各有优点。-Speech enhancement of voice recognition is an important component of system performance. In order to compare the performance of speech enhancement algorithm using the Matlab software, a numerical simulation, speech under different noise environments with 3 different methods of noise reduction, the use of signal to noise ratio, endpoint detection method to the noise reduction effect, and a few kinds of enhanced performance of the algorithm were compared. The results show that changing the noise environment in the MMSE method was the best short-term spectrum, spectral subtraction and Wiener filtering methods have their advantages.

Description: The problem of noise reduction has attracted a considerable amount of research attention over the past several decades. Among the numerous techniques that were developed, the optimal Wiener filter can be considered as one of the most fundamental noise reduction approaches, which has been de-lineated in different forms and adopted in various applications. Although it is not a secret that the Wiener filter may cause some detrimental effects to the speech signal (appreciable or even sig-nificant degradation in quality or intelligibility-SINCE we are living in a natural environment where noise is inevitable and ubiquitous, speech signals are gener-ally immersed in acoustic ambient noise and can seldom be recorded in pure form. Therefore, it is essential for speech processing and communication systems to apply effective nois

[Software Engineering8-optimal_in_FRFTdomains

Description: time-invariant degradation models and stationary signals and noise, the classical Fourier domain Wiener filter, which can be implemented in O(N logN) time, gives the minimum mean-square-error estimate of the original undistorted signal. For time-varying degradations and nonstationary processes, however, the optimal linear estimate requires O(N2) time for implementation. We consider filtering in fractional Fourier domains, which enables significant reduction of the error compared with ordinary Fourier domain filtering for certain types of degradation and noise (especially of chirped nature), while requiring only O(N logN) implementation time. Thus, improved performance is achieved at no additional cost. Expressions for the optimal filter functions in fractional domains are derived, and several illustrative examples are given in which significant reduction of the error (by a factor of 50) is obtained.
