ABSTRACT:
A detection circuit for the significant peaks of a speech signal, comprising first and second detectors respectively for detecting the positive and negative peaks of said speech signal. Each of these detectors is followed by a peak charging circuit comprising a first integrator having a relatively large discharge time constant and a comparator comparing the detected speech signal and the output signal of said first integrator. Each peak charging circuit comprises in addition a second integrator having a relatively small time-constant. The discharge of the first integrator is effected up to a voltage equal to the output voltage of the second integrator, and the discharge of the second integrator is effected down to a voltage depending on the output voltage of the first integrator. The two integrators of each peak charging circuit provide a non-exponential decreasing signal which has an inflection point following a significant peak in the original speech signal.
