Spectrograms spectrograms are used to show spectral densityit has a horizontal axis of time,a vertical axis showing the frequency and a third axis showing the intensityfor a given spectrogram s, the strength of a given frequency component f at a given time t in the speech signal is represented by the darkness or color of the corresponding.
