Please refer to Fig. 2, be embodiment of the invention concrete grammar flow chart, can may further comprise the steps:
Step 201: control module starts the wireless network vocal quality assessment;
Step 202: control module is by calling the interface that is used to send, and the control computer sends sample upload request (Sample Upload REQ) to caller;
Step 203: after caller received Sample Upload REQ from computer, the interface that is used to receive that calls by control module returned sample to control module and uploads response (Sample UploadACK);
Step 204: the interface that is used to send of control module by calling, the control computer sends reference paper to caller;
Computer can be by the USB interface that links to each other with caller, sends reference paper to caller with the form of speech frame.
Step 205: after transmission finished, the interface that is used to send of control module by calling, control computer send to transmit to caller finished notice (Transfer Finish Notify);
Step 206: after caller receives Transfer Finish Notify, call out calledly, and connect by wireless network (such as the base station);
Step 207: the interface that is used to receive that caller is called by control module, the notice control module connects to be set up;
Step 208: the interface that is used to send of control module by calling, the control computer sends beginning playing request (Start Play REQ) to caller, simultaneously, begins recording request (StartRecord REQ) to called transmission;
Step 209: the interface that is used to receive that caller is called by control module returns to control module and begins to play response (Start Play ACK), and the called interface that is used to receive that calls by control module returns to control module and begins recording response (Start Record ACK);
Step 210: caller begins to play reference paper after returning Start Play ACK immediately, called return Start Record ACK after, immediately by set up with begin recording being connected of caller;
In called recording, the called interface that is used to receive that calls by control module is sent to control module with the degradation file of recording.Called USB interface by linking to each other with computer is sent to control module with degradation file with the form of speech frame.
Step 211: after caller was play and finished, the interface that is used to receive that calls by control module sent broadcast end notification (Play Finish Notify) to control module;
Step 212: after control module receives Play Finish Notify, stop recording order (Stop Record Notify) by its interface that is used to send that calls to called transmission immediately;
Step 213: the called Stop Record Notify that receives, after the interface that is used to receive that calls by control module all is sent to control module with degradation file, finish notice (Upload Frame Finished Notify) to the control module echo-plex;
Step 214: control module receives from behind the called Upload Frame Finished Notify by the interface that is used to receive that calls, and control module begins to control computer and carries out voice quality scoring MOS.
Control module can be called the voice appraisal procedure of standard, for example: and voice quality Auditory estimating (PESQ, Perceptual Evaluation of Speech Quality), carry out MOS.Further, finish MOS after, to user's output mos result.
