FIELD: acoustics; data processing.
SUBSTANCE: invention relates to the speech reproducing device, intended for the speech reproduction based on the received speech signal so, that the reproduced speech was legible in the clear speech zone, and illegible in the masked speech zone, at that, the speech reproduction device comprises: audio processing module, configured to receive the speech signal; set of speech loudspeakers, configured to reproduce speech based on one or more speech loudspeakers signals; and set of the masking sound loudspeakers, configured to create the masking sound based on one or more masking sound loudspeaker signals, at that, the masking sounds is masking speech in the masked speech area; at that, the audio processing module comprises the speech analysis module, configured to generate one or more analysis signals based on the speech signal spectral and / or temporal characteristics, audio processing module comprises the masking sound generator, configured to generate one or more masking sound signals based on one or more analysis signals.
EFFECT: speech reproduction on the basis of the received speech signal.
