Talk deciding system

摘要

A talk deciding system includes a receiving portion which receives far-end side decision information indicating a talking state on a far-end side, an inputting portion which inputs an emitted signal from the far-end side, a speaker which emits the emitted signal being input into the inputting portion, a microphone which picks up a voice on a near-end side and outputs a picked-up signal, and a deciding portion which preliminarily decides a talking state on the near-end side based on the picked-up signal being output from the microphone and the emitted signal being input into the speaker, and generates near-end side decision information indicating a talking state on the near-end side. The deciding portion decides the talking state on the near-end side based on the far-end side decision information being received at the receiving portion and the near-end side decision information.

主权项

1. A talk deciding system, comprising:
a receiving portion which receives from a far-end side far-end side decision information indicating a talking state on the far-end side; an inputting portion which inputs an emitted signal from the far-end side; a speaker which emits the emitted signal being input into the inputting portion; a microphone which picks up a voice on a near-end side and outputs a picked-up signal; a deciding portion which preliminarily decides a preliminary talking state on the near-end side based on the picked-up signal being output from the microphone and the emitted signal being input into the speaker, and generates near-end side decision information indicating the preliminary talking state on the near-end side, wherein the deciding portion decides a final talking state on the near-end side based on the far-end side decision information being received at the receiving portion and on the near-end side decision information; a transmitting portion which attaches the near-end side decision information generated by the deciding portion to voice information based on the picked-up signal, and transmits the near-end side decision information and the voice information to the far-end side; and an echo suppressor which attenuates the voice signal to be output to the far-end side, wherein the deciding portion sets whether or not an attenuation should be made by the echo suppressor and a level of attenuation, based on the decided final talking state on the near-end side.
