Abstract

The invention discloses an intelligent conference telephone with mouth shape identification. The intelligent conference telephone comprises a camera, a mouth shape identification module and a loud speaker controller. The camera captures head images of participants and generates multi-frame pictures expressing the head images. The mouth shape identification module identifies the states of mouth shapes according to the multi-frame pictures and generates control signals expressing the states of the mouth shapes. The loud speaker controller receives the control signals and controls a loud speaker according to the control signals. Compared with the prior art, when a participant in a conference room is talking, the intelligent conference telephone can automatically shield speech of the same person reflected from other conference rooms. Therefore, interference caused by echoes is reduced, and the connection quality is improved.

Tele-conferencing system is widely used in commercial operational environment.This conference system generally comprises the multiple terminals intelligent telephone set connected by network, such as: the intelligent telephone set of an office directly can carry out voice or Video chat with other one or more offices by wireless network or telecommunications cable network.That is, the sound that the staff that the smart phone of an office receives this office sends, and pass to other office by network, sounded by the intelligent telephone set of this another office, thus reach the object of interchange.Some intelligent telephone sets in tele-conferencing system of the prior art may using after the sound newly received is spread out of by loud speaker again as Speech input, be sent to the other end of teleconference, thus make sound interference large, sound effect is poor.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of intelligent telephone set, with at reduction interference of call signal, improves speech quality.

For solving the problems of the technologies described above, the present invention adopts following technical scheme:

The invention provides a kind of intelligent meeting telephone set with nozzle type identification, comprising:

Loud speaker, for sounding according to voice signal;

Microphone, for receiving the sound importing described intelligent meeting telephone set into;

Network interface, described network interface interconnection network;

The acoustic processing module be connected with described microphone with described loud speaker, for the treatment of the signal of telecommunication that described network interface transmits, and is converted to voice signal by the described signal of telecommunication, sends described loud speaker to; Further, described acoustic processing module receives the voice signal that described microphone transmits, and is converted into first signal of telecommunication;

The coding decoder be connected with described acoustic processing module with described network interface, for being encoded by described first signal of telecommunication, and sending first signal of telecommunication after coding to described network interface, sending to described network by described network interface; Further, described coding decoder receives second signal of telecommunication from described network interface, and decodes to described second signal of telecommunication, sends described acoustic processing module to;

It is characterized in that, described intelligent meeting telephone set also comprises:

Camera, for catching the head portrait of personnel participating in the meeting, and produces the multiframe picture representing described head portrait;

Nozzle type identification module, for the state according to described multiframe picture recognition nozzle type, and produces the control signal representing described nozzle type state; And

Raising one's voice controller, for receiving described control signal, and controlling described loud speaker according to described control signal.

In one embodiment, when described control signal represents that described personnel participating in the meeting speaks, described in controller of raising one's voice close described loud speaker; When described control signal represents that described personnel participating in the meeting does not speak, described in controller of raising one's voice open described loud speaker by described control signal.

Compared with prior art, when the personnel participating in the meeting of a meeting room is when speech, the speech of the same person that intelligent meeting phone function automatic shield reflects from other meeting rooms.Thus, reduce the interference that revolution sound causes, improve speech quality.

Accompanying drawing explanation

Figure 1 shows that intelligent meeting telephone system according to an embodiment of the invention.

Figure 2 shows that intelligent meeting telephone set according to an embodiment of the invention.

Figure 3 shows that the system construction drawing of intelligent meeting telephone set according to an embodiment of the invention.

Embodiment

Below will provide detailed description to embodiments of the invention.Although the present invention will carry out setting forth and illustrating in conjunction with some embodiments, it should be noted that the present invention is not merely confined to these execution modes.On the contrary, the amendment carry out the present invention or equivalent replacement, all should be encompassed in the middle of right of the present invention.

In addition, in order to better the present invention is described, in embodiment hereafter, give numerous details.It will be understood by those skilled in the art that do not have these details, the present invention can implement equally.In other example, known method, flow process, element and circuit are not described in detail, so that highlight purport of the present invention.

Figure 1 shows that intelligent meeting telephone system 100 according to an embodiment of the invention.In intelligent meeting telephone system 100, the staff in a meeting room carries out voice conference call by intelligent meeting telephone set 102 and the staff of another meeting room in strange land.

Figure 2 shows that intelligent meeting telephone set 102 according to an embodiment of the invention.In the embodiment of fig. 2, intelligent meeting telephone set 102 comprises receiver 202, microphone 204, loud speaker 206 and camera 208.When many people carry out videoconference, the microphone 204 opening intelligent meeting telephone set 102 carries out hand-free call.In addition, also can select to receive sound with receiver 202.

Figure 3 shows that the system construction drawing 300 of intelligent meeting telephone set 102 according to an embodiment of the invention.In the embodiments of figure 3, intelligent meeting telephone set 102 comprises the network interface 314 be connected with network 304.Intelligent meeting telephone set 102 also comprises loud speaker 204 and microphone 206.Loud speaker 204 is sounded according to receiving from network 304 voice signal come.Microphone 206 receives in meeting room the sound importing intelligent meeting telephone set 102 into.In addition, intelligent meeting telephone set 102 also comprises acoustic processing module 310 and coding decoder 312.Acoustic processing module 310 is connected with microphone 204 with loud speaker 206, for the treatment of the signal of telecommunication that network interface 314 transmits, and this signal of telecommunication is converted to voice signal, sends loud speaker 206 to, thus loud speaker 206 is sounded.Further, acoustic processing module 310 receives the voice signal that microphone 204 transmits, and is converted into first signal of telecommunication.Coding decoder 312 is connected with acoustic processing module 310 with network interface 314, for being encoded by first signal of telecommunication, and sending first signal of telecommunication after coding to network interface 314, being issued to corresponding network by network interface 314; Further, coding decoder 312 receives second signal of telecommunication from network interface, and decodes to second signal of telecommunication, sends acoustic processing module 310 to, passes to loud speaker 206 after carrying out acoustic processing by acoustic processing module 310.
