ABSTRACT:
In order to reduce the information contents of a sound signal, for example a speech signal, the sound signal is divided into adjacent frequency ranges and the signals then obtained are consecutively integrated over short time intervals to short-time-spectrum signals. Subsequently, a histogram of the short-time-spectrum signals is formed for each frequency range and said histograms are divided into a given number of equal-area portions. The boundaries of said portions, which are referred to as quantiles, represent the characteristic values. The amplifier noise or the noise of the complete recording arrangement as well as a difference in sound energy level during when different sound signals are processed can then be eliminated at least in respect of their effect.
