Characteristic parameter, and reception time of described voice signal and spectrum signature parameter.
In this step, after controller 100 receives the successful information of output of voice output device 110 return, to memory
160 instructions sending storage test signal and output timing.Memory 160 is receiving the finger of storage test signal and output timing
After order, store the spectrum signature parameter of test signal and the output time of test signal.Controller 100 receives signal detector
After the successful information of confirmation of 140 returns, send storage of speech signals and the instruction of reception timing to memory 160.Memory
160 receive storage of speech signals and receive timing instruction after, the spectrum signature parameter of storage of speech signals and voice signal
The reception time.
Step 250, when the spectrum signature of described voice signal is consistent with the spectrum signature of described test signal, calculator
170 obtain the output time T1 of test signal described in described memory 160 and described voice letter under the control of the controller 100
Number reception time T2, and calculate time difference △ T=T2-T1 between the two.
In this step, after controller 100 receives the successful information of confirmation of signal detector 140 return, to calculator
170 transmission computationses.Calculator 170 after receiving computations, obtain memory 160 in test signal output time and
The reception time of voice signal, and calculate the output time of test signal and the difference of the reception time of voice signal.This difference
It is the voice delay time of tested speech ciphering equipment 20.
Here should be pointed out that the execution step of the tested speech time delay method of the present invention is not limited thereto, any
Be familiar with those skilled in the art in the case of the principle without departing substantially from the present invention and thought, the adjustment to said method step or

Survey instruction.Voice receiver 120 receives, after receiving reception instruction, the voice signal returning through tested speech ciphering equipment 20, and sends
To signal detector 140.After receiving detection instruction, whether monitoring voice receiver 120 first receives signal detector 140
Voice signal, if receiving voice signal, returning to controller 100 and receiving successful information, and on client terminal device 40
Display receives successfully, otherwise returns the information of reception failure to controller 100, and shows that on client terminal device 40 reception is lost
Lose, thus terminating this test.Further, signal detector 140 receives voice signal monitoring voice receiver 120
Afterwards, whether the spectrum signature of detection voice signal is consistent with the spectrum signature of test signal, when confirming consistent, to controller
100 return and confirm successful information, and shows on client terminal device 40 and confirms successfully, otherwise to controller 100 return confirmation
The information of failure, and show on client terminal device 40 and confirm unsuccessfully, thus terminating this test.
Step 370, after controller 100 receives the successful information of confirmation of signal detector 140 return, to timer
150 send reception riming instructions.Timer 150, after receiving reception riming instructions, records the reception time T2 of voice signal.
Step 380, after controller 100 receives the successful information of confirmation of signal detector 140 return, to calculator
170 transmission computationses.Calculator 170, after receiving computations, obtains the output time T1 of test signal in memory 160
With the reception time T2 of voice signal, and signal detector 140 from monitor voice signal to confirm voice signal time
FT, the time difference between the reception time T2 of the output time T1 of test signal and voice signal is deducted letter by calculator 170 again
Number detector 140 from monitoring voice signal to the time FT confirming voice signal, as tested speech ciphering equipment 20 voice when
Prolong △ T, i.e. △ T=T2-T1-FT.
It is an advantage of the invention that：
1) wireless talkback terminal, wired intercom terminal, voice inter-speaking system, broadcast call system can rapidly be tested
Voice delay time, convenient and swift, accuracy is high.
2) 3.5 millis of 3.5 millimeters of earphone interfaces of test device compatibility national standard (OMTP) and international standard (CTIA)
Rice earphone interface, can conveniently test all kinds of wireless terminal devices.
3) tested speech ciphering equipment need not be carried out destroying, transform, lead.For at present compared with the verbal system of main flow, for example
Mobile phone, speech talkback equipment etc., being directly connected to test device using the existing earphone interface of equipment can easily tested speech
Time delay.
4) test of multi-path voice time delay can be carried out simultaneously.
5) test device is not limited to laboratory test, is also applied for test under vehicle-mounted mobile state.
6) test device contains the oscillographic interface of connection, in laboratory conditions not only can tested speech time delay, also
The waveform that test device sends and receives can be checked, can detect speech waveform transmit through tested speech ciphering equipment after distortion feelings
Condition.
The above, only the present invention be embodied as case, protection scope of the present invention is not limited thereto, any ripe
Know those skilled in the art in technical specification of the present invention, modifications of the present invention or replacement, all should be in the present invention
Protection domain within.
