My doubt is in regards to the usage of the function
cceps in Matlab.
The function is giving me the cepstrum for the entire speech signal of 3 or 4sec. This works well when I play back the signal after taking the inverse (using the
icceps function). However, in order to analyze the given speech signal, we are supposed to only consider 20ms frame.
Is taking the complex cepstrum throughout the signal valid? Why is it working out here?
