Abstract

The invention discloses a remote conference system and a multi-microphone voice signal recognition and playing method, and the method comprises the steps: building the ID and face features of participants during conference sign-in, binding portable wireless microphones, obtaining the voice signal of each portable wireless microphone in real time through a sign-in machine during a conference, recognizing the microphone ID, and playing the voice signal of each portable wireless microphone through the sign-in machine. Sending a voice signal of the portable wireless microphone corresponding to the microphone ID to the conference machine for playing; meanwhile, the face features of the speaking person are obtained through the microphone ID and sent to the conference machine, and the conference machine recognizes the current speaking person in the conference place video according to the face features, focuses on the current speaking person and identifies the current speaking person. According to the invention, on one hand, the voice signal of the portable wireless microphone corresponding to the current speaking person is sent to the conference machine for playing, and the voice of each speaking person in the teleconference is very clear; on the other hand, the current spokesman can be identified, and the conference effect is improved.

Description

technical field [0001] The invention relates to the technical field of teleconferencing, in particular to a teleconferencing system and a multi-microphone voice recognition playback method. Background technique [0002] With the development of communication technology, the application of teleconferencing is becoming more and more common. The video display and voice playback of the speaker in the remote conference are two key factors that affect the effect of the conference. The existing teleconferencing system has the following defects: [0003] First, remote conference systems usually use omnidirectional microphones to meet the needs of participants to speak. However, when the conference site space is large and there are many participants, due to the different distances between the participants and the omnidirectional microphone, the speech signal obtained by the omnidirectional microphone is relatively small for the speaker who is far away, resulting in a low voice. , i...
