Abstract
The invention discloses a handshaking signal processing method of a voice assessment algorithm in a voice test system, which comprises a test terminal capable of carrying out unattended operation, a matched equipment database, a background server and the like, wherein the voice quality assessment algorithm is preset on the background server, the test process comprises the following steps that: the test terminal and the background server establish a voice calling; the test terminal and the background server send DTMF (dual-tone multifrequency) handshaking signals to each other; and the test terminal and the background server verify the handshaking signals, a timer is turned on after no error is found in the verification, and meanwhile, the test is started according to the preset voice quality assessment algorithm. The invention has the advantages that the handshaking is realized through the DTMF voice, the playing action of the source end and the recording action of the target end are synchronized, the complexity of the system is greatly reduced, and the stability and the cost performance of the system can be improved.
Description
Technical field
The invention provides a kind of end-to-end speech quality detecting method, can in cordless communication network, carry out end-to-end speech quality evaluation test.
Background technology
In the prior art, some confessed in the world voice assessment algorithms are followed in the voice quality test usually, comprise ITU-T PESQ speech quality evaluation algorithm P.862+P.862.1, the PAMS speech quality evaluation algorithm of ITU-TP.800, ITU-T PSQM/PSQM+ speech quality evaluation algorithm P.861, the E-Model speech quality evaluation algorithm of ITU-TG.107.The part of its core essence all is to do a contrast to the speech waveform file of source speech waveform file and generation, according to corresponding algorithm, calculates current voice quality parameters.
Present tone testing equipment all is the unit version, is applicable to small lot, fixed test.The system that can carry out long-time uninterrupted extensive voice quality test in 7 * 24 hours does not also have ripe scheme.
In the communication process, terminal can be by sending dual-tone multifrequency (Double Tone Multi-Frequency is hereinafter to be referred as DTMF) signal to the opposite end, this technology is widely used in existing all commercial signal communication systems, for example: dial 168 information service centers, after the connection, voice suggestion " is used Chinese please by 1 ", at this moment clicks " 1 " key, it is " 1 " that receiving terminal can pick out this, and the typical case of Here it is DTMF one of uses.
In large-scale automatic speech quality test system,, need system to record automatically owing to can't carry out manual intervention.And in existing speech quality evaluation algorithm, if source file is inconsistent with the voice document length that receives, then will has a strong impact on the assessment result of voice quality, thereby can not truly correctly react actual conditions.If the voice document that receives is handled with program, which picks out is various noises in ring back tone and the call establishment, need use speech recognition technology, realizes very complicated from technology, need a large amount of coding and test job, cost performance is too low.
Summary of the invention
The object of the present invention is to provide the handshake processing method of voice assessment algorithm in a kind of tone testing system, can between two network elements, carry out the voice quality test, and assess speech quality.
The present invention is achieved by the following scheme:
The handshake processing method of voice assessment algorithm in the tone testing system, comprise the test terminal that to carry out unattended duty, corollary equipment database, background server etc., preestablish the speech quality evaluation algorithm on background server, test process may further comprise the steps:
A, test terminal and background server are set up audio call;
B, terminal send the DTMF handshake to background server;
C, background server checking handshake, verify errorless after, open timer, begin to test according to the speech quality evaluation algorithm of setting in advance simultaneously;
Behind D, the EOT, both sides are hung up calling, and background server is stored in test result in the database simultaneously;
In the process of steps A, B, C, background server opens that DTMF surveys and identification, in case find follow-uply still have dtmf tone to pass to come, judgement is butt call or other artificial disturbance in the system, then stops this time test.
The speech quality evaluation algorithm that is adopted comprises P.861 PSQM/PSQM+ speech quality evaluation algorithm of P.800 PAMS speech quality evaluation algorithm of P.862+P.862.1 PESQ speech quality evaluation algorithm of ITU-T, ITU-T, ITU-T, ITU-T E-Model speech quality evaluation algorithm G.107 etc.
Effect of the present invention is: shake hands by dtmf tone, the playback action of source end and the recording of destination are moved synchronously, greatly reduce the complexity of system, improved the stability and the cost performance of system.
Embodiment
The handshake processing method of voice assessment algorithm in the tone testing system, comprise the test terminal that to carry out unattended duty, corollary equipment database, background server etc., preestablish the speech quality evaluation algorithm on background server, test process may further comprise the steps:
A, test terminal and background server are set up audio call;
B, terminal send the DTMF handshake to background server;
C, background server checking handshake, verify errorless after, open timer, begin to test according to the speech quality evaluation algorithm of setting in advance simultaneously;
Behind D, the EOT, both sides are hung up calling, and background server is stored in test result in the database simultaneously;
In the process of steps A, B, C, background server opens that DTMF surveys and identification, in case find follow-uply still have dtmf tone to pass to come, judgement is butt call or other artificial disturbance in the system, then stops this time test.
The speech quality evaluation algorithm that is adopted comprises P.861 PSQM/PSQM+ speech quality evaluation algorithm of P.800 PAMS speech quality evaluation algorithm of P.862+P.862.1 PESQ speech quality evaluation algorithm of ITU-T, ITU-T, ITU-T, ITU-T E-Model speech quality evaluation algorithm G.107 etc.
1. test macro can carry out corresponding wireless calling on the set time point of system, sets up conversation and keeps;
2. after conversation keeps, the source end is the prior DTMF sound of setting of Play System at first, DTMF can be " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 ", " * ", " # ", " A ", " B ", " C ", " D ", " E " any one combination, can in system, set in advance, as " #1234 ";
3. after the source end sent " #1234 ", beginning playing standard tested speech after the second after receiving terminal is surveyed and recognized " #1234 ", started sound-recording function and begins recording after the second;
The effect of patent of the present invention is: in large-scale automatic speech quality test system, owing to can't carry out manual intervention, need system automatically to record. And in existing speech quality evaluation algorithm, if source file is inconsistent with the voice document length that receives, then will has a strong impact on the assessment result of voice quality, thereby can not truly correctly react actual conditions. If with program the voice document that receives is processed, which picks out is various noises in ring back tone and the call establishment, need to use speech recognition technology, realizes very complicated from technology, need a large amount of coding and test job, cost performance is too low. Shake hands by dtmf tone, the playback action of source and the recording of destination are moved synchronously, greatly reduce the complexity of system, improved Systems balanth and cost performance.
