It is understood that there may be more than one for destination mobile terminal, when there are the movement of more than two targets is whole When end, there is also two or more for corresponding target range, can determine the anti-place that utters long and high-pitched sounds using the target range of numerical value minimum as standard The target strength of reason.
In some embodiments, the target strength that anti-processing of uttering long and high-pitched sounds is determined according to the target range, including:According to The target range determine in the mobile terminal ascending voice communicating data and/or downlink voice communicating data prevent It utters long and high-pitched sounds processing.Wherein, it when the target range is more than the second pre-determined distance value, determines to the uplink language in the mobile terminal Sound communicating data carries out anti-processing of uttering long and high-pitched sounds;When the target range is more than third pre-determined distance value and is less than or equal to described second When pre-determined distance value, determines and anti-processing of uttering long and high-pitched sounds is carried out to the downlink voice communicating data in the mobile terminal;When the target When distance is less than or equal to the third pre-determined distance value, determine to the ascending voice communicating data in the mobile terminal under Row voice communication data carry out anti-processing of uttering long and high-pitched sounds.Downlink voice communicating data general data amount is larger, chauvent's criterion intractability It is slightly larger, it takes and slightly grows, therefore, in the embodiment of the present application, be less than the first pre-determined distance value in target range but preset more than second Apart from when, utter long and high-pitched sounds if illustrating to generate, degree of uttering long and high-pitched sounds is not serious, and the anti-place that utters long and high-pitched sounds can be carried out only for ascending voice communicating data Reason.When target range is less than or equal to the second pre-determined distance value, but is more than third distance value, utters long and high-pitched sounds, utter long and high-pitched sounds if illustrating to generate Degree can carry out anti-processing of uttering long and high-pitched sounds than more serious for downlink voice communicating data, to obtain preferably anti-effect of uttering long and high-pitched sounds. When target range very little, when being less than or equal to third pre-determined distance value, to utter long and high-pitched sounds if illustrating to generate, the degree of uttering long and high-pitched sounds can be very serious, It can be directed to downlink voice communicating data simultaneously and downlink voice communicating data carries out anti-processing of uttering long and high-pitched sounds, to obtain best anti-howl It is effect.The numerical value of the first pre-determined distance of the application couple, the second pre-determined distance and third pre-determined distance is sequentially reduced, but to specific Numerical value does not limit, and illustratively, the first pre-determined distance is 10 meters, and the second pre-determined distance is 5 meters, and third pre-determined distance is 2 meters.
Illustratively, to downlink voice communicating data carry out it is anti-utter long and high-pitched sounds processing when, can be first to downlink voice communicating data Carry out detection of uttering long and high-pitched sounds, judge to exist utter long and high-pitched sounds sound when, an attenuation processing is carried out for uttering long and high-pitched sounds, to reach anti-effect of uttering long and high-pitched sounds.
In some embodiments, under type such as can be used to judge in downlink voice communicating data with the presence or absence of sound of uttering long and high-pitched sounds:
The first, piecemeal processing is carried out to the downlink voice communicating data;For each data block, using presupposition analysis Mode determines doubtful present in current data block utter long and high-pitched sounds a little;When exist present periodic feature multiple doubtful point groups of uttering long and high-pitched sounds, And it is doubtful when uttering long and high-pitched sounds that a little corresponding energy value is in rising trend according to the sequence of affiliated data block, determine the downlink voice call There is sound of uttering long and high-pitched sounds in 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 default model Doubtful in enclosing is uttered long and high-pitched sounds a little, and the quantity of the continuous adjacent data block reaches default continuous threshold value.
Second, piecemeal processing is carried out to the downlink voice communicating data, obtains M data block;Using presupposition analysis Mode is analyzed in current data block and is uttered long and high-pitched sounds a little with the presence or absence of doubtful successively, will be first appeared the doubtful data block uttered long and high-pitched sounds a little and is determined as Initial data block;From the initial data BOB(beginning of block), successively with n data block for data segment to be analyzed, using described default Analysis mode analyze include in current data section doubtful utter long and high-pitched sounds a little, when include in N number of data segment it is doubtful utter long and high-pitched sounds a little between Frequency difference when being in preset range, determine there is sound of uttering long and high-pitched sounds in the downlink voice communicating data;Wherein, n=2, 3 ..., N;N is less than or equal to M, is greater than or equal to 2;Starting point of the starting point of each data segment with the initial data block Identical, the initial data block is first data segment.
Certainly, other modes also can be used in the embodiment of the present application to judge in downlink voice communicating data with the presence or absence of howl Sound, the application is made not to limit.It is described in detail by taking above-mentioned two ways as an example below.
For first way, to downlink voice communicating data carry out piecemeal processing can be according to default unit length into The processing of row piecemeal, it for example can be 40 milliseconds to preset unit length.Assuming that predetermined time period is 1.2 seconds, unit length is preset It it is 40 milliseconds, then 30 data blocks can be divided into.
The embodiment of the present application is not especially limited presupposition analysis mode.For example, the presupposition analysis mode may include: The frequency point to be determined that energy value in high-frequency region is higher than preset energy threshold value is obtained on frequency domain, is calculated around the frequency point to be determined The capacity volume variance value of the frequency point of preset quantity determines described to be determined when the capacity volume variance value is more than default discrepancy threshold Frequency point is doubtful utters long and high-pitched sounds a little;The high-frequency region is the frequency range that frequency is higher than predeterminated frequency threshold value.
Specifically, for current data block, frequency domain can be first transformed from the time domain to, spectrum analysis is convenient for.Transformation Mode the embodiment of the present application does not limit, and Fourier transformation mode may be used, such as the fast algorithm (Fast of discrete fourier transform Fourier Transformation, FFT).By taking 40ms as an example, audio data (16bit, 16k sample rate) size of 40ms is 40*16*16/2=1280 bytes, are adapted for use with 1024 and do FFT transform and carry out spectrum analysis, by FFT treated frequencies Frequency range in analysis is 0~16K/2, and step-length is (16K/2)/1024, and step-length is about 8Hz.
In the embodiment of the present application, high-frequency region and other regions can be divided using predeterminated frequency threshold value as cut off value.In advance If frequency threshold can be configured according to actual conditions, such as can according to voice frequency and be susceptible to the frequency feature of howling into Row setting, such as can be 1KHz, 1.5KHz or 2KHz etc..Such as predeterminated frequency threshold value is 2KHz, that is, is more than the portion of 2KHz It is divided into high-frequency region.The frequency of general howling appears in high-frequency region, and sound is larger (i.e. energy value is higher), the application Embodiment can quickly determine that a data are in the block according to energy value characteristic distributions and doubtful utter long and high-pitched sounds a little.
Illustratively, the corresponding energy value of each Frequency point (abbreviation frequency point) in data block is obtained, then from high-frequency region In find energy value be higher than preset energy threshold value frequency point to be determined, calculate the energy of the frequency point of preset quantity around frequency point to be determined Measure difference value.Preset energy threshold value and preset quantity can be arranged according to actual demand, for example, preset energy threshold value can be- 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.
In addition, the presupposition analysis mode may also include:Energy value maximum first in high-frequency region is obtained on frequency domain Maximum second frequency point of energy value in frequency point and low frequency region, when first frequency point meet it is default it is doubtful utter long and high-pitched sounds condition when, really Fixed first frequency point be current data it is in the block it is doubtful utter long and high-pitched sounds a little, it is described that preset the doubtful condition of uttering long and high-pitched sounds include first frequency point Energy value be more than preset energy threshold value, and the energy differences of first frequency point and second frequency point are more than preset difference value threshold Value.
Specifically, for current data block, frequency domain can be first transformed from the time domain to, spectrum analysis is convenient for.Equally It can also preset and divide frequency as cut off value to divide high-frequency region and low frequency region.Default division frequency can be according to practical feelings Condition is configured, and can be such as configured according to voice frequency and the frequency feature for being susceptible to howling, such as can be 1KHz, 1.5KHz or 2KHz etc..Such as the default frequency that divides is 2KHz, that is, the part for being more than 2KHz is high-frequency region, is less than or waits In the part of 2KHz be low frequency region.
Illustratively, the corresponding energy value of each Frequency point in data block is obtained, energy is then found from high-frequency region It is worth maximum first frequency point, maximum second frequency point of energy value is found from low frequency region, if the energy value of the first frequency point is more than in advance If energy threshold (such as -30dB), and the difference of the energy value of the energy value of the first frequency point and the second frequency point is more than preset difference value threshold When being worth (such as 60), it is believed that the first frequency point, which is that current data is in the block, doubtful utters long and high-pitched sounds a little.Setting can rapidly and accurately be known in this way Do not go out 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, for each data block, presupposition analysis mode as above is respectively adopted and judges whether doubtful utter long and high-pitched sounds Point, and if it exists, then record it is doubtful utter long and high-pitched sounds a little, and whether further judge in current downlink voice communicating data comprising uttering long and high-pitched sounds Sound.
It is understood that if there are doubtful sounds of uttering long and high-pitched sounds in some data block, whole section of downlink voice call can not be thought Include sound of uttering long and high-pitched sounds in audio, it is also possible to since certain especial sounds are misidentified as sound of uttering long and high-pitched sounds, such as be generated when object friction Ear-piercing sound, 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 generally compares Very briefer, 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 be a little known as 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.
