Abstract
The invention discloses an intelligent conference telephone set. The intelligent conference telephone set comprises a tone recognition module and a loudspeaker controller. In a starting mode, the tone recognition module detects first electric signals transmitted to a network interface from a coder-decoder, extracts tone characteristic data in the first electric signals and stores the tone characteristic data in a tone characteristic database. In a normal operation mode, the tone recognition module monitors electric signals on the connecting line between the coder-decoder and the network interface, the electric signals on the connecting line are compared with the tone characteristic data in the tone characteristic database, and control signals are generated according to a comparison result. The loudspeaker controller controls a loudspeaker according to the control signals. Compared with the prior art, when a participant in a conference room speaks, the intelligent conference telephone set can automatically shield the speech, reflected back from other conference rooms, of the same participant. Thus, the interference caused by echoes is reduced, and the conversation quality is improved.

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 tamber characteristic database 314, tone color identification module 316 and controller 318 of raising one's voice.Tamber characteristic database 314 stored sound characteristic.Tone color identification module 316 is connected with tamber characteristic database 314 with coding decoder 312.Tone color identification module 316 works in power on mode and normal operation mode.In power on mode, tone color identification module 316 detects first signal of telecommunication reaching network interface 314 from coding decoder 312, extracts the tamber characteristic data in first signal of telecommunication, and by tamber characteristic data stored in tamber characteristic database 314.In the normal operating mode, tone color identification module 316 monitors the signal of telecommunication between coding decoder 312 and network interface 314 on connecting line, the signal of telecommunication relatively on connecting line and the tamber characteristic data in tamber characteristic database 314, and produce control signal according to comparative result.Controller 318 of raising one's voice is connected with described tone color identification module with described loud speaker, for according to described control signal control loudspeaker 206.
More particularly, when the staff of meeting room loquiturs time, tone color identification module 316 can extract the tamber characteristic of the sound of the one or more staff in this meeting room, and will represent that the data of these tamber characteristics are stored into tamber characteristic database 314.When the staff of other long-range meeting rooms starts speech time, tone color identification module 316 can identify and whether the sound judging to import into 100 of conference telephone system is the sound of the people of this meeting room, that is, be whether the revolution sound of people's sound after importing the other side's meeting room into of this meeting room.
In one embodiment, when the tamber characteristic data in the signal of telecommunication on described connecting line and tamber characteristic database 314 do not mate (namely judging that this voice signal is not revolution sound), controller 318 of raising one's voice opens loud speaker 206 by described control signal.When tamber characteristic data match (namely judging that this voice signal is revolution sound) in the signal of telecommunication on connecting line and tamber characteristic database 314, controller 318 of raising one's voice is by control signal mute speaker 206.
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.
