Abstract
The invention discloses an intelligent conference telephone set with a feature recognition function. The intelligent conference telephone set comprises a feature code adding device, a feature recognizer and a loudspeaker controller. The feature code adding device adds a feature code representing the intelligent conference telephone set to an encoded sound electrical signal and then sends the sound electrical signal to the network. The feature recognizer detects the feature code of electrical signals received from a network interface, and produces a control signal according to the detection result. The loudspeaker controller controls a loudspeaker according to the control signal. Compared with the prior art, when a participant in a conference room speaks, the intelligent conference telephone set can automatically shield the speech, reflected by other reference rooms, of the participant. Therefore, the intelligent conference telephone set with the feature recognition function reduces interference caused by sound reflection and improves communication quality.

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 and loud speaker 206.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.
In one embodiment, intelligent meeting telephone set 102 also comprises condition code adder 316, feature identifier and controller 320 of raising one's voice.Condition code adder 316 is connected with network interface 314, adds the condition code representing intelligent meeting telephone set 102, and produce the fisrt feature code signal of telecommunication, to be sent to network 304 by network interface 314 for first signal of telecommunication after giving coding.Feature identifier 318 is connected with network interface 314, for detecting the condition code of second signal of telecommunication received from network interface 314, and produces control signal according to the condition code of second signal of telecommunication.Controller 320 of raising one's voice is connected with loud speaker 206 with feature identifier 318, for reception control signal, and according to control signal control loudspeaker 206.
More particularly, the telephone set of each meeting room has unique condition code, and this condition code is becoming a kind of characteristic sounds after acoustic processing module process.This kind of characteristic sounds can be followed the propagation of sound medium and propagate.When the condition code of secondary signal represents that this secondary signal is mated with intelligent meeting telephone set 102 (explanation is the echo of active conference room), controller 320 of raising one's voice is by described control signal mute speaker 206.When the condition code of secondary signal represent that secondary signal is not mated with intelligent meeting telephone set 102 echo of active conference room (illustrate be not) time, controller 320 of raising one's voice opens loud speaker 206 by described control signal.
Advantage is, when the personnel participating in the meeting of a meeting room is when speech, and the speech of the same person that intelligent meeting telephone set 102 energy automatic shield reflects from other meeting rooms.Thus, reduce the interference that revolution sound causes, improve speech quality.
Embodiment and accompanying drawing are only the conventional embodiment of the present invention above.Obviously, various supplement, amendment and replacement can be had under the prerequisite not departing from the present invention's spirit that claims define and invention scope.It should be appreciated by those skilled in the art that the present invention can change in form, structure, layout, ratio, material, element, assembly and other side under the prerequisite not deviating from invention criterion according to concrete environment and job requirement in actual applications to some extent.Therefore, be only illustrative rather than definitive thereof in the embodiment of this disclosure, the scope of the present invention is defined by appended claim and legal equivalents thereof, and is not limited thereto front description.
