Instantaneous-frequency distribution vs. time: An interpretation of the phase structure of speech

A new time-frequency display is constructed based on the phase of the running short-time Fourier transform, specifically the distribution of its time derivative. Typical results are given for speech, indicating more precise location of formants than is usual for the spectrogram.
