代码说明:

  学习并找到降噪方法,对语音信号背景噪声做处理,使得声音更清晰。(The background noise is the most common factor degrading the quality and intelligibility of speech in recordings. Spectral subtraction can lower the noise level without affecting the speech signal quality. In this paper, we have studied and implemented to reduce the background noise of the voice signal, and to make improvements to reduce the background noise of the experiment. Not only with the spectral subtraction of the noisy signal of the transformation, we improve the traditional spectral subtraction based on the introduction of the parameters, by adjusting the parameters(α、β、γ) to achieve better enhancement.)

    語音信號是基於時間軸上的一維數位信號,在這裏主要是對語音信號進行頻域上的分析。在信號分析中,頻域往往包含了更多的資訊。對於頻域來說,大概有8種波形可以讓我們分析:矩形方波,鋸齒波,梯形波,臨界阻尼指數脈衝波形,三角波,餘旋波,余旋平方波,高斯波。對於各種波形,我們都可以用一種方法來分析,就是傅立葉變換:將時域的波形轉化到頻域來分析。(Voice signal is based on the timeline of one-dimensional digital signal, where mainly the speech signal in frequency domain analysis. In signal analysis, frequency domain often contains more information. For the frequency domain for about 8 allows us to analyze waveforms: rectangular square wave, sawtooth, trapezoidal wave, the critical damping index pulse, triangle wave, I spin wave, I spin square wave, Gaussian. For all waveforms, we can analyze in a way that is Fourier transform: the transformation of time domain waveform into the frequency domain to analyze)
