Abstract
The invention discloses a voice synthesizing system which comprises a plurality of voice encoding and decoding devices and a plurality of multi-service transmitting devices, wherein the plurality of voice encoding and decoding devices are respectively positioned in a plurality of conference halls; and the plurality of multi-service transmitting devices are respectively connected with the encoding and decoding devices and a voice mixing device. The voice synthesizing system disclosed by the invention can meet the requirement that conference members scattered in various places hold a conference by using a command control system, and more conference members participate in and freely speak in real time, so that the most conference members from 64 places can freely speak without any speaking application operation after entering the conference.
Description
Technical field
The present invention relates to the speech processes field, relate in particular to speech synthesis system.
Background technology
In command and control system, conference member is distributed in different positions usually, and each conference member is generally a meeting-place or post on duty, often requires to hold the more meeting of number of members, and requires to ensure the promptness of response.The most conference systems of current industry are fixedly way audio mixing; Conferenced party needs the request floor seat during speech, needs the speech control strategy accordingly, can't accomplish the real-time, freedom speech; The most multipartite voice synthetic technologys that adopt in the meeting adopt is the mode of simple speech stack or through the software control conference member; Noise is bigger more for a long time at conference member easily in simple voice stack, and the conference member number is too much unsuitable, and conference member is no more than 32 sides usually; Software mode can expand to quite on a large scale conference member quantity, but the real-time response of the distributed meeting that disperses for conference member often can not ensure, also easily because mistake appears in maloperation.
Summary of the invention
The problems referred to above to existing in the prior art the invention provides speech synthesis system.
The invention provides speech synthesis system, comprising: lay respectively at a plurality of encoding and decoding speech devices in a plurality of meeting-place, and the multi-service conveyer that is connected with device sound mixing with coding and decoding device respectively.
In one example, said a plurality of be 64.
In one example, the signal that transmits between multi-service conveyer and the encoding and decoding speech is the signal of encoding and decoding speech device collection or the signal behind the device sound mixing audio mixing.
In one example, the signal that transmits between multi-service conveyer and the device sound mixing is the signal of encoding and decoding speech device collection or the signal behind the device sound mixing audio mixing.
In one example, do not comprise the voice signal of energy in the signal behind the audio mixing less than preset value.
The present invention can satisfy the requirement that command and control system that conference member disperses various places is held a meeting; And satisfy the more requirement with real-time, freedom speech of conference member number; Make that maximum 64 side's conference members can be after getting into meeting, need not to do any speech application operation and can freely make a speech.
Description of drawings
Come the present invention is done further explain below in conjunction with accompanying drawing, wherein:
Fig. 1 is a speech synthesis system of the present invention.
Embodiment
Speech synthesis system provided by the invention is as shown in Figure 1, comprises the encoding and decoding speech device that lays respectively at n meeting-place, and the encoding and decoding speech device is connected to the multi-service conveyer, and the multi-service transfer system is connected with device sound mixing.
The multi-service conveyer transfers to device sound mixing with the voice signal in each meeting-place, and behind the device sound mixing audio mixing, the multi-service conveyer transfers to the signal behind the audio mixing encoding and decoding speech device in each meeting-place again.Device sound mixing detects its speech signal energy that receives, and energy does not carry out audio mixing less than the voice signal of preset value.
The multi-service conveyer has a plurality of nodes, and voice signal transfers on the node nearby; Dispose one or more VC12 or VC4 between node as internodal virtual trunk; Dividing each professional shared time slot on the configured virtual relaying, also can come to select automatically hollow time slot through software; Finish if relaying is occupied, when needing Added Business, reconfigure VC12 or VC4, and divide each professional shared time slot as internodal virtual trunk.
At first the decode voice signal of multi-service conveyer transmission of device sound mixing carries out noise reduction process and extracts energy factors decoded voice signal.Noise reduction process mainly is the analysis through the long period, extracts the numerical range of noise place voice data, and on this basis, the timeslice of the pure noise signal of zero setting, all the other timeslices then deduct the pre-estimation noise signal.Extract energy factors and be meant different according to the importance of each participant side and participation, distribute each signal to carry out the weight (energy factors) of audio mixing intelligently.The weight that device sound mixing also distributes according to each participant side is carried out audio mixing to each voice signal.Signal behind the audio mixing is carried out smoothing processing and stabilizes processing.Smoothing processing is that the signal behind the audio mixing is carried out The disposal of gentle filter, stabilizes that to handle be that the voice signal of timeslice that some volume is excessive is forced to force down in valid value range, prevents that spillover from taking place.The audio signal that to handle is at last carried out coding and transmitted to each encoding and decoding speech device.
The present invention can realize " teleconference " that maximum 64 side's conference members are participated in; In use, can pass through software dynamic assignment conference member, thereby can practice thrift conferencing resource, when total conference member quantity is no more than 64 sides, hold the meeting of many groups; In a single day the member who participates in a conference gets in the meeting, then can make a speech at any time, need not to do other operation, has omitted in the conference system in the past in the software design the control of meeting, has simplified software design.
The above is merely preferred implementation of the present invention, but protection domain of the present invention is not limited thereto.Any those skilled in the art all can carry out suitable change or variation to it in technical scope disclosed by the invention, and this change or variation all should be encompassed within protection scope of the present invention.
