matlabVoice
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)
