SPEECH PROCESSING SYSTEM |
摘要 |
A speech processor having microprocessor control of the amplitude level of input speech signals. Input speech signals are applied to a digitally controlled level regulator, the output of which is converted into a digital speech signal for further speech processing. The peak level of the digital speech signals over a frame period is compared in the microprocessor with a preset optimum range. If the peak level falls outside the optimum range, control signals for the level regulator are adjusted in a direction to change the amplification/attenuation amount of the level regulator to bring the peak level within the optimum range. |
