Specific embodiment
Embodiments herein is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or has the function of same or like element.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the application, and it is not intended that limitation to the application.
Below with reference to the accompanying drawings processing method, device, electronic equipment and calculating that the voice of the embodiment of the present application is uttered long and high-pitched sounds are described
Machine readable storage medium storing program for executing.
Fig. 1 is the flow chart for the processing method uttered long and high-pitched sounds according to the voice of the application one embodiment.It should be noted that this
The processing method that the voice of application embodiment is uttered long and high-pitched sounds can be applied to the processing unit that the voice of the embodiment of the present application is uttered long and high-pitched sounds, the processing
Device can be configured in electronic equipment.Wherein, in embodiments herein, which can be mobile terminal (such as hand
Machine, tablet computer, personal digital assistant etc. have the hardware device of various operating systems).
As shown in Figure 1, the processing method that the voice is uttered long and high-pitched sounds can include：
Whether S110, detection current scene meet the chat scenario that closely multi-person speech is hands-free.Wherein, the application's
In embodiment, the hands-free chat scenario of the closely multi-person speech is used to indicate in closely scene, and there are more people to pass through
The scene of hands-free mode voice-enabled chat.
It should be noted that be adapted to closely multi-person speech hands-free for the processing method that the voice of the embodiment of the present application is uttered long and high-pitched sounds
Chat scenario, for example, suitable for more people's athletic games closely hands-free scene, there are echo amount is excessive due to closely hands-free
The problem of, it can to occur under hands-free scene self-excitation and utter long and high-pitched sounds problem.
In this step, it can detect whether current scene meets the chat scenario that closely multi-person speech is hands-free, if satisfied,
Step S120 is then performed, i.e., processing of uttering long and high-pitched sounds is carried out to the voice signal collected.As a kind of exemplary realization method, can pass through
Testing audio is sent to current scene, and is detected whether to receive in certain period of time after other equipment first receives by microphone
The testing audio exported by loud speaker, if so, can determine that the current scene is hands-free for closely multi-person speech
Chat scenario.
S120, if so, the voice signal in acquisition chat scenario, and the voice signal of the present frame collected is converted
For frequency-region signal.
Optionally, detect current scene meet described in closely multi-person speech hands-free chat scenario when, can pass through
Microphone gathers the voice signal in the chat scenario, and Discrete Fourier Transform or discrete cosine transform can be used or change
Into cosine transform, the voice signal of the present frame collected is converted into frequency-region signal.Wherein, in embodiments herein
In, the present frame is that frame in the voice signal for receiving the current time after the voice signal framing, obtained
Signal.
S130 extracts the feature of frequency-region signal.
As a kind of exemplary realization method, the single-frequency energy of the frequency point and the frequency point in the frequency-region signal can extract.It can
Selection of land can determine multiple sampling frequency points in the frequency-region signal according to preset sample frequency, wherein, each sampling frequency point is right
Answer a frequency.
For example, the voice signal collected is carried out framing, under the preset sample frequency, multiple sampling frequencies are included per frame
Point, wherein, frequency point refers to specific absolute frequency value, is after being sampled according to the preset sample frequency to every frame signal, incites somebody to action
After being ranked up per all frequencies gathered in frame signal, obtained number, so, each frequency point that samples corresponds to a frequency
Rate.
After the frequency point in extracting the frequency-region signal, it may be determined that the single-frequency energy of the frequency point.For example, due to each sampling
Frequency point corresponds to a specific signal frequency, so, each single-frequency energy sampled corresponding to frequency point is exactly that the frequency point corresponds to
Signal frequency energy (i.e. the range value of the corresponding signal frequency of the frequency point).
S140, whether the voice signal that present frame is judged according to the feature of frequency-region signal is signal of uttering long and high-pitched sounds.
Optionally, can determine whether the frequency point in the frequency-region signal and single-frequency energy is to judge the voice signal of the present frame
No is signal of uttering long and high-pitched sounds.As a kind of exemplary realization method, can determine whether frequency point in the frequency-region signal single-frequency energy whether
In preset time period exponentially type rise, if so, determine whether this exponentially type rise after single-frequency energy value it is whether big
In predetermined threshold value, if so, can determine that the voice signal of the present frame for signal of uttering long and high-pitched sounds.
That is, the single-frequency energy of the frequency point in preset time period can be counted, and judge the single-frequency energy of the frequency point
Amount whether in the preset time period exponentially type rises and is more than predetermined threshold value, if so, can determine that the language of the present frame
Sound signal is signal of uttering long and high-pitched sounds.
S150, if so, the voice signal of present frame is removed.
Optionally, the voice signal for judging the present frame for utter long and high-pitched sounds signal when, the signal of the access can be removed.
As a kind of example, processing can be reset to the frequency-region signal and is converted back into time domain to eliminate signal of uttering long and high-pitched sounds.Thus, it is possible to it avoids making a whistling sound
Calling excessive causes echo to inhibit sordid problem.
In conclusion the processing method that the voice of the embodiment of the present application is uttered long and high-pitched sounds, is chatted for closely multi-person speech is hands-free
Its scene, due to closely it is hands-free there are echo amount it is excessive the problem of, in general background sound and human voice signal are smaller, work as detection
The signal risen to single-frequency nergy Index type, and when the signal amplitude is more than certain threshold value, it can be by the target signal filter, to reduce back
The input quantity of sound avoids winding self-excitation, while improves double stress results.
According to the processing method that the voice of the embodiment of the present application is uttered long and high-pitched sounds, whether detectable current scene meets closely more people
The hands-free chat scenario of voice, if so, the voice signal in acquisition chat scenario, and the voice of the present frame collected is believed
Number frequency-region signal is converted to, and extracts the feature of frequency-region signal, and judge that the voice of present frame is believed according to the feature of frequency-region signal
Number whether it is signal of uttering long and high-pitched sounds, if so, the voice signal of present frame is removed.It is i.e. hands-free for closely multi-person speech
Chat scenario, due to closely it is hands-free there are echo amount it is excessive the problem of, in general background sound and human voice signal are smaller, work as root
According to the feature of frequency-region signal detect exist utter long and high-pitched sounds signal when, which can be removed, avoid howling is excessive from causing back
Sound inhibits sordid problem, and then the situation of winding the self-oscillation amplifying occurs, improve it is double stress results, and improve making for user
With experience.
