It is corresponded with the outer audio signal segment of putting of corresponding period；The standard source of sound in speech quality evaluation algorithm is substituted for respectively
Sound source signal section；The comparison source of sound in speech quality evaluation algorithm is substituted for outer playback frequency corresponding with sound source signal section respectively
Signal segment；It calculates separately standard source of sound and compares the MOS value of source of sound, obtain multiple MOS values；The average value of multiple MOS values is taken, is made
For related coefficient.
Signal is divided into multistage and calculates separately the available accurate MOS value of MOS value, avoids recorded audio signals by the external world
The not accurate enough problem of test result caused by interfering.
Preferably, speech quality evaluation algorithm are as follows: PESQ algorithm, or, POLQA algorithm.Specifically, being put outside will be collected
Signal and reference source of sound are directed respectively into PESQ algorithm, are proceeded as follows:
1, selected sound source signal, the collected source of sound of MIC are divided into every section of the signal of 10s；Wherein, as long as source of sound
Signal segment is corresponded with the outer audio signal segment of putting of corresponding period, it is not necessary to which the time span of every section of voice signal is all
Unanimously, for example, source of sound time span can also increase into a ladder, 10s, 20s, 30s.
2, the P.863 standard source of sound in PESQ algorithm is substituted for the reference source of sound divided；
3, the comparison source of sound in PESQ algorithm is substituted for the collected source of sound of MIC divided；
4, PESQ algorithm is run, MOS score value is calculated.
Further, the outer playback matter of terminal is determined according to related coefficient, comprising: related coefficient is higher, then terminal is outer
The higher grade of playback matter.The grade of the outer playback matter of terminal includes at least following one: excellent, good etc., medium, poor etc., bad
Deng；Wherein, when related coefficient is more than or equal to first threshold, the grade of the outer playback matter of terminal is excellent；Related coefficient is less than
One threshold value and when being more than or equal to second threshold, the grade of the outer playback matter of terminal is good etc.；Related coefficient be less than second threshold and
When more than or equal to third threshold value, the grade of the outer playback matter of terminal is medium；Related coefficient is less than third threshold value and is more than or equal to
When four threshold values, the grade of the outer playback matter of terminal is difference etc.；Related coefficient is less than or equal to the 4th threshold value and is more than or equal to the 5th
When threshold value, the grade of the outer playback matter of terminal is of inferior quality；The 4th threshold value > of first threshold > second threshold > third threshold value >
Five threshold values.
The definition of MOS score value specifically can be used such as under type:
| Rank | MOS score value | Subjective perceptual quality |
| Top grade | 5.0 | Very good, non-delay distortion is more suitable than sound source signal effect |
| Good grade | 4.0 | Good, subjective perception effect and sound source signal are close |
| Middle rank | 3.0 | Generally, subjective perception effect is more slightly worse than sound source signal |
| Poor grade | 2.0 | Difference, subjective perception is poorer than sound source signal, there is interrupted, distortion |
| Bad grade | 1.0 | It is very poor, have serious distortion, discontinuously, compared with sound source signal, subjective perception is very poor |
MOS score value is higher, illustrates the signal put outside mobile phone closer to original signal, the fidelity of outer discharge signal is got over
Height can reflect out the quality put outside music to a certain extent.
