Abstract

The proposed device for extracting indications of speech signals contains the first acoustic transducer and the first signal former, connected in series, and the second acoustic transducer. To the second acoustic transducer, the circuit is connected that contains the second signal former, amplitude detector, two threshold units, and a comparator. The circuit of each signal former contains an output voltage amplifier, a voltage divider, and a pulse selector. The second acoustic transducer is disposed at a specified distance from the first acoustic transducer.
