FIELD: voice communications.
SUBSTANCE: voice communication device generates the transmitted speech signal to be transmitted to the far-end speaker. The voice communication device includes a loudspeaker that emits a received speech signal, which is the voice signal of the far-end speaker, a first microphone that captures the acoustic signal as a first audio captured signal, the acoustic signal comprising the speaker's voice, which is the voice that speaks the near-end speaker, and a playback sound that is obtained by emitting a received speech signal, and a second microphone that captures the acoustic signal as a second audio captured signal, the acoustic signal comprising the speaker's voice and a playback sound. In this case, the voice communication method comprises: a correction step, a first subtraction step, an adaptive filtering step, and a second subtraction step.
EFFECT: increased efficiency of communication.
