Spectrogram of r
Webspectrogram: R k= X f X t kP (f f ;t rt T) S(f;t)k2 (1) where kf f kk Hk 2 and kt rt k Tk Wk. If the patch is placed at a portion near the borders of the spectrogram, then the intervals in the integral of Equation 1 are truncated to their valid limits. If there are Kpatches in our dictionary, then the spectro- WebR-colored vowels can be articulated in various ways: the tip or blade of the tongue may be turned up during at least part of the articulation of the vowel (a retroflex articulation) or …

Webspectrogram Function Use the spectrogram function to compute the STFT of the signal. Divide the signal into segments, each M = 49 samples long. Specify L = 11 samples of overlap between adjoining segments. Discard the final, shorter segment. Window each segment with a Bartlett window.

I finally figured out what I was missing, that should get rid of the overly huge voicebar: pre-emphasis. Pre-emphasis is a simple one-tap high-pass filter, a.k.a. a differentiator, or more correctly, a differencer.
