ABSTRACT:
In a voice operated gain adjust for a voice processor included an input range adjust (10), a sixteen channel amplifier (12), an analog to digital converter (14) and a microcomputer (16). An audio signal including voice signals and background noise is applied to the input of the range adjust (10) and the amplifier (12). The output of the input range adjust (10) is applied through the A/D converter (14) to the microcomputer (16). The microcomputer (16) distinguishes voice signals from background noise and controls the gain of the amplifier (12) in accordance with the amplitude of the voice signals. Also, the microcomputer (16) controls the gain of the input range adjust (10) so that the input signal to the A/D converter (14) is within the operating range of the converter (14).
