Abstract
A voice signal processing device detects a near-end talker included in an image, specifies a direction in which the near-end talker is located, detects a voice arrival direction based on a voice signal collected by a microphone array, estimates whether the near-end talker is uttering, based on the direction in which the near-end talker is located and the voice arrival direction, sets an amplification factor of the voice signal to a value equal to or greater than 1 in a case where the near-end talker is estimated to be uttering, sets the amplification factor of the voice signal to a value smaller than 1 in a case where the near-end talker is estimated not to be uttering, and adjusts a level of the voice signal based on the set amplification factor, and outputs the adjusted voice signal as a transmission signal to be transmitted to a far-end talker.
