Pierre Deman, Jean Potage: Arrangement for discriminating speech signals from noise. Thomson-CSF, Cushman Darby & Cushman, June 19, 1979: US04158749 (7 worldwide citation)

An audio squelch circuit uses spectral analysis of the audio signal to derive two test signals, one of the two indicating speech presence "energy" and the other "voiced" speech presence. The two test signals are logic-AND combined to decide speech presence and open the squelch gate. Detection of spe ...

Pierre Deman, Jean Potage: Speech processing device for radioelectric equipment adapted for speech transmission and reception. Thomson-CSF, Cushman Darby & Cushman, December 31, 1985: US04562571 (3 worldwide citation)

The device is of the type comprising a circuit for compressing the dynamic of the speech signal before transmission of the signal at constant level and an expander for re-establishing at reception the speech level before compression thereof. A logic filtering circuit controls the compression circuit ...
