10dB, preset quantity can be 8 (before frequency point to be determined 4 and 4 below).By taking step-length above is about 8Hz as an example, it is assumed that
The frequency values of frequency point to be determined be 3362Hz, then around it frequency values of frequency point of preset quantity be about 3330Hz, 3338Hz,
3346Hz, 3354Hz, 3370Hz, 3378Hz, 3386Hz and 3394Hz.Capacity volume variance value is for weighing frequency point to be determined and surrounding
Difference degree between the frequency point of preset quantity can be specifically the difference of maximum energy value and minimum energy value, can also be energy
Variance yields or energy mean square deviation etc. are measured, the application does not limit.Default discrepancy threshold and corresponding, the example of capacity volume variance value
Such as, when capacity volume variance value is energy variance yields, it is default variance threshold values to preset discrepancy threshold.When capacity volume variance value is poor more than default
When different threshold value, illustrate frequency point to be determined than more prominent, is very likely to be to utter long and high-pitched sounds a little, accordingly, it is determined that frequency point to be determined is doubtful
It utters long and high-pitched sounds a little.In this way setting can rapidly and accurately identify it is doubtful utter long and high-pitched sounds a little, lay the first stone to improve detection efficiency of uttering long and high-pitched sounds.
Illustratively, there may be multiple frequency points to be determined, the application in a data block can be highest from corresponding energy
Frequency point to be determined proceeds by the doubtful judgement uttered long and high-pitched sounds a little.
Step 104, when there is multiple doubtful point groups of uttering long and high-pitched sounds that periodic feature is presented, and doubtful a little corresponding energy of uttering long and high-pitched sounds
When value is in rising trend according to the sequence of affiliated data block, determine there is sound of uttering long and high-pitched sounds in the downlink voice communicating data.
Wherein, the doubtful point group of uttering long and high-pitched sounds is that continuous adjacent data frequency difference in the block is in doubtful in preset range
It utters long and high-pitched sounds a little, the quantity of the continuous adjacent data block reaches default continuous threshold value.
Illustratively, if there are doubtful sounds of uttering long and high-pitched sounds in some data block, it can not think whole section of downlink voice call audio
In comprising uttering long and high-pitched sounds sound, it is also possible to since certain especial sounds are misidentified as sound of uttering long and high-pitched sounds, such as thorn that when object rubs generates
The sound of ear, general frequency is higher and sound is larger, it is likely that is identified as doubtful sound of uttering long and high-pitched sounds, but this sound is generally shorter
Promote, the duration is shorter, is not belonging to sound of uttering long and high-pitched sounds, and therefore, it is necessary to increase further judgement.
In the embodiment of the present application, the characteristic distributions of doubtful sound of uttering long and high-pitched sounds present in each data block are analyzed.When continuous
When uttering long and high-pitched sounds there are smaller doubtful of frequency difference in multiple adjacent data blocks, these doubtful utter long and high-pitched sounds can a little be become doubtful howl
It is point group.That is, doubtful point group of uttering long and high-pitched sounds be that continuous adjacent data frequency difference in the block is in preset range it is doubtful utter long and high-pitched sounds a little,
The quantity of the continuous adjacent data block reaches default continuous threshold value.Wherein, preset continuous threshold value can determines according to actual conditions,
Such as 3；The corresponding preset range of frequency difference also can determines according to actual conditions, such as 40Hz.Inventor's discovery, howling
Characteristics of SSTA persistence is generally shown in a short time, and is periodically occurred, and in addition sound becomes larger.Therefore, the application is implemented
In example, periodic feature is presented into multiple (can be regarded as be greater than or equal to 2) doubtful point groups of uttering long and high-pitched sounds and doubtful is uttered long and high-pitched sounds a little pair
The energy value answered is in rising trend as decision condition according to the sequence of affiliated data block, to identify current downlink voice call
With the presence or absence of sound of uttering long and high-pitched sounds in data, if meeting above-mentioned condition, it is determined that there is sound of uttering long and high-pitched sounds, can rapidly and accurately identify in this way
It utters long and high-pitched sounds sound.
Illustratively, it is assumed that downlink voice communicating data is divided into 30 data blocks.If for example, the 1st, 2,3,7,8,9,
13, frequency is all detected in the section (A-40, A+40) in 14,15,19,20,21,25,26 and 27 this 15 data blocks
Doubtful to utter long and high-pitched sounds a little, corresponding doubtful utter long and high-pitched sounds of every 3 data blocks a little becomes a doubtful point group of uttering long and high-pitched sounds, and 5 doubtful point groups of uttering long and high-pitched sounds are in
Periodic feature, and doubtful a little corresponding energy value of uttering long and high-pitched sounds is sequentially increased, accordingly, it is determined that including howl in downlink voice communicating data
It is sound.For another example, it utters long and high-pitched sounds if detecting doubtful in the section (B-40, B+40) of frequency in this 3 data blocks of only the 1st, 2 and 3
Point, corresponding doubtful utter long and high-pitched sounds of this 3 data blocks a little becomes a doubtful point group of uttering long and high-pitched sounds, but there is only this, and week is not presented
Phase property feature, accordingly, it can be determined that not including sound of uttering long and high-pitched sounds in downlink voice communicating data.
