In the process of hearing, the human ear develops a short-time spectrum of its acoustic input. Information-bearing features of the signal are retained in this spectral analysis. An understanding of the process by which the human auditory system preserves perceptually significant features is valuable in developing speech-transmission techniques. An example of effort in this direction is the phase vocoder.
