Figure 3From: Single channel speech separation in modulation frequency domain based on a novel pitch range estimation methodSound mixture and its modulation spectrogram. (a) Mixture of speech signals. (b) T-F energy plot for a mixture of two utterances of a male speaker. The utterances are "eight" and "dos." For better display, energy is plotted as the square of the FT. (c) Modulation spectrogram of the mixture signal.Back to article page
