Abstract
An improvement of the speech spectrogram based on the method of reassi gnment is presented. This method consists of moving each point of the spectrogram to a new point that represents the distribution of the ene rgy in the time-frequency window more accurately. Examples of natural speech show an improvement of the energy localization in both time and frequency domains. This allows a better description of speech feature s.
