Detailed Description
The core of the application is to provide a control method and device of an earphone, an electronic device and a computer readable storage medium, which can enable a user wearing the earphone to notice the communication requirement initiated by external voice in time and improve the use experience of the user on the earphone.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a method for controlling an earphone provided in the present application, where the method for controlling an earphone includes:
s101: acquiring an external signal through a microphone device of an earphone;
it can be understood that, a microphone device for collecting voice signals is generally arranged on the earphone, and the present embodiment obtains external signals through the existing microphone device on the earphone, so as to achieve the purpose of saving hardware cost. The external signal in this embodiment specifically refers to all signals except the audio signal inside the earphone, that is, a mixed signal from the outside of the earphone body including noise and/or voice signals.
Specifically, the external signal can be acquired according to a preset acquisition cycle, so that the communication requirement initiated by the external voice cannot be omitted by a user wearing the earphone in any environment, and certainly, the external signal can be acquired by triggering a microphone device of the earphone in certain specific environments, such as a noisy environment and when the earphone is in a noise reduction mode, so that the data processing amount is reduced. The trigger condition for acquiring the external signal is selected and set according to the actual working condition, and the application is not specifically limited herein.
S102: judging whether the target voice signal exists in the external signal, if so, executing S103;
s103: and controlling a loudspeaker of the earphone to output the target voice signal.
Specifically, the external signal is analyzed after the external signal is obtained, and whether the target voice signal exists in the external signal is judged. Specifically, feature calculation may be performed on the external signal, whether a target speech signal exists in the external signal is determined according to a set of feature data obtained by the feature calculation, and if the set of feature data includes feature data that meets the distribution characteristics of the speech data, it may be determined that the target speech signal exists in the external signal. As a preferred embodiment, the feature calculation may be performed by MFCC (Mel Frequency Cepstral Coefficients ), GFCC (gamma Frequency Cepstral Coefficients, gamma pass Cepstral Coefficients), or the like, so as to improve the accuracy of determining whether the target speech signal exists in the external signal.
Specifically, when a target voice signal exists in the external signal, the path between the microphone device and the loudspeaker of the earphone is communicated, so that the target voice signal is output through the loudspeaker, and no matter whether the earphone is in the noise reduction mode currently, an earphone wearer can timely notice the external communication requirement according to the target voice signal output by the loudspeaker, and if the target voice signal does not exist, the current working mode of the earphone is not controlled and adjusted.
It is thus clear that this embodiment can gather external signal through the microphone device of earphone, when judging that there is the target speech signal in the external signal, the speaker through the earphone exports this target speech signal to make the earphone person of wearing can in time notice the communication demand that external pronunciation originated, improve the user and experience the use of earphone.
Referring to fig. 2, a flow chart of another earphone control method provided by the present application is shown, which includes the following steps:
s201: acquiring an external signal through a microphone device of an earphone;
s202: judging whether the target voice signal exists in the external signal, if so, executing S203;
s203: detecting whether a preset keyword exists in the target voice signal, if so, executing S204;
s204: and controlling a loudspeaker of the earphone to output the target voice signal.
Specifically, the earphone wearer may preset some keywords according to a requirement, where the preset keywords may be words, phrases or sentences corresponding to external needs for communicating with the earphone wearer himself, for example, contents related to the name and the gender of the earphone wearer may be set as the preset keywords, and for example, the name "zhang san" and the gender "man" of the earphone wearer may be set as the preset keywords. When the target voice signal exists in the external signal, as a preferred embodiment, firstly, the target voice signal is subjected to voice enhancement so as to facilitate subsequent keyword identification, and then whether the preset keyword exists in the target voice signal is judged according to the enhanced target voice signal, if not, the target voice signal is not possibly sent to the earphone wearer, and the target voice signal can not be processed, so that the content played by the earphone of the earphone wearer at present can not be influenced, and the user experience is further improved. If the target voice signal has the preset keyword, the speaker of the earphone is controlled to output the target voice signal, so that the earphone wearer can accurately and timely acquire the communication requirement sent to the wearer from the outside.
For example, assuming that the content corresponding to the target voice signal is "three shoes are laced open", after the target voice signal is acquired, detecting the content of the target voice signal, matching the content with a preset keyword, and matching the name of the earphone wearer, so that it can be determined that the target voice signal is a communication requirement sent from the outside to the earphone wearer, and at this time, controlling a speaker to output the target voice signal. Assuming that the content corresponding to the target voice signal is 'lady your and the like', after the target voice signal is acquired, detecting the content of the target voice signal, and matching the content with a preset keyword, wherein the content does not have characters, words or sentences matched with the preset keyword, so that the target voice signal can be judged not to be a communication requirement sent to an earphone wearer from the outside, and the signal is not processed.
Referring to fig. 3, a flow chart of another earphone control method provided by the present application is shown, which includes the following steps:
s301: acquiring an external signal through a microphone device of an earphone;
s302: judging whether the target voice signal exists in the external signal, if so, executing S303 and S304;
s303: when the target voice signal exists in the external signal, the gain value of the original signal path of the loudspeaker is reduced to a preset value or the original signal path is controlled to be closed;
s304: and controlling a loudspeaker of the earphone to output the target voice signal.
S303 and S304 may be executed simultaneously, or S303 and S304 may be executed first, and the execution sequence of S303 and S304 is not limited in the present application.
Specifically, in order to enable the earphone wearer to clearly obtain the communication demand sent to the earphone wearer from the outside, the volume of the audio file currently played by the loudspeaker can be adjusted down to a preset value. Specifically, when it is determined that a target voice signal exists in the external signal and the target voice signal has content corresponding to a preset keyword, the gain value of the original signal path of the speaker is adjusted to a preset value or the original signal path is controlled to be closed, so that the volume of an audio file being played by the speaker is reduced or suspended, and after the communication between the microphone device and the speaker is ensured, the volume of the target voice signal output by the speaker is higher than the volume of the audio file being played by the speaker, therefore, a user wearing the earphone can clearly and accurately acquire a communication demand sent to the user wearing the earphone, and the user experience of the earphone is further improved.
As a preferred embodiment, the target speech signal obtained by the microphone device may be further processed by tracking enhancement, and the target speech signal is speech-compensated, so as to avoid partial incompleteness of speech information caused by signal reception and noise suppression processes at the microphone device, thereby improving the quality and intelligibility of the target speech signal.
On the basis of the above-described embodiment:
as a preferred embodiment, before controlling the speaker of the headphone to output the target voice signal, the method for controlling the headphone further includes:
carrying out blind source separation on the target voice signal to obtain a target human voice signal;
the process of controlling the speaker of the headset to output the target voice signal includes:
and controlling a loudspeaker of the earphone to output the target human voice signal.
Specifically, considering that the obtained target speech signal may include other noises in addition to the human voice, the present embodiment also performs blind source separation on the target speech signal, and extracts a simple human voice from the target speech signal, that is, the target human voice speech signal in the present embodiment. Specifically, in order to obtain a simple target voice signal, the present embodiment performs independent component analysis on the target voice signal, so as to analyze the target voice signal, and may convert such problems into a matrix processing problem, and in consideration of factors such as a target voice separation effect and a separation speed, the present embodiment may specifically use a fixed point algorithm (also called FastlCA) and a fixed point algorithm of a maximized negative entropy to find an optimal unmixed matrix, and estimate an independent target voice signal mixed by unknown factors from a mixed target voice signal, so that an earphone wearer can accurately obtain content of a communication requirement sent from the outside to the earphone wearer, so that the earphone wearer can timely make feedback.
Of course, in addition to the blind source separation by using the above method, other methods may also be used to obtain the target human voice signal from the mixed target voice signal, and the application is not limited in this respect.
As a preferred embodiment, the microphone arrangement comprises a microphone array comprising n microphone paths, n being an integer larger than 1.
Each microphone path comprises a microphone, and considering that a microphone array is originally arranged on some earphones at present, the microphone array in the embodiment is an existing microphone array on the earphones, and for earphones without the microphone array, the microphone array can be added on the outer side of the earphones.
In this embodiment, the external signal is obtained by the microphone array, and it can be understood that each microphone obtains the external signal, so the external signal in S101 is a mixed external signal output by a plurality of microphones.
As a preferred embodiment, the control method of the headset further comprises:
positioning a sound source of a target voice signal according to phase difference parameters corresponding to each microphone channel in the microphone array;
and when the sound source does not output the target voice signal any more within the preset time period, controlling the loudspeaker to recover the initial working mode.
It can be understood that, because the position of each microphone in the microphone array is different, there is a different phase difference parameter between each microphone and the sound source, and the phase difference parameter can be used to implement sound source localization, sound source tracking, blind source separation, etc.
The following describes a process of locating a sound source of a target speech signal according to phase difference parameters corresponding to respective microphone paths in a microphone array:
referring to fig. 4, when the time (or sound pressure level) from the sound source signal to M2 and M3 is less than the time to M1 and M4, the system in the two-dimensional space will automatically locate the sound source in the corresponding quadrant, and after the sound source is located in the corresponding quadrant, according to the pythagorean theorem, the distance from the sound source to M2 and M3 can be obtained, and at this time, the two-dimensional position corresponding to the sound source is obtained. After the sound source moves to the 1 position after the time t, the quadrant and the specific position of the sound source at the 1 position can be obtained in the same way, so that the sound source is positioned and tracked. Furthermore, the directivity of blind source separation can be enhanced according to the direction of the sound source, only the target voice signal in the direction of the sound source is subjected to blind source separation, and the accuracy of extracting the target voice signal from the mixed target voice signal is improved.
Further, if the tracked sound source does not output the target speech signal any more for a duration, the speaker is controlled to return to the initial operation mode, such as the noise reduction mode, specifically the operation mode before S103 is executed.
As a preferred embodiment, after the external signal is acquired by the microphone device of the headset, the control method of the headset further includes:
judging whether a wind noise signal exists in an external signal;
and if so, determining a microphone path with the minimum wind noise interference in the microphone array through disturbance analysis, and taking the microphone path as a feedforward noise reduction path.
Specifically, the external signal is analyzed after being acquired, and whether a wind noise signal exists in the external signal is judged. Specifically, feature calculation can be performed on the external signal, whether a wind noise signal exists in the external signal is judged according to a group of feature data obtained through the feature calculation, and if the group of feature data includes feature data according with the distribution characteristics of the wind noise data, it can be judged that the wind noise signal exists in the external signal. As a preferred embodiment, the feature calculation may be performed by means of MFCC, GFCC, or the like, so as to improve the accuracy of determining whether the target speech signal exists in the external signal.
When a wind noise signal exists, considering that the influence of the wind noise on microphones at different positions is different, judging a microphone path with the minimum wind noise interference in the microphone array through disturbance analysis, wherein it can be understood that the microphone path with the minimum signal energy fluctuation in each microphone array is subjected to the minimum wind noise interference, and determining the microphone path where the microphone is located as a feedforward noise reduction path, so that the influence of the wind noise on a feedforward noise reduction system is reduced, and the working robustness of active noise reduction in different environments is improved.
It can be understood that the feedforward noise reduction path is not constant, and as the position of the wearer of the headphone changes, the wind noise has a new influence on the microphones at different positions, and at this time, the microphone path with the minimum wind noise interference in the microphone array is determined again through the disturbance analysis, and the microphone path is used as a new feedforward noise reduction path.
In the application, the correlation processing of the wind noise signal and the correlation processing of the target speech signal are independently performed and do not interfere with each other.
To sum up, this application acquires the external signal through the microphone array that the earphone outside set up, when there is wind in the external signal and makes an uproar, consider that this noise influences the microphone of different positions differently, the less passageway of signal energy fluctuation will be regarded as feedforward noise reduction microphone passageway, until replaced by the less passageway of another signal energy fluctuation, in noisy environment, carry out the keyword to the target speech signal in the external signal and discern, when the keyword is picked up the back, the earphone opens penetrating mode, give the earphone instruction immediately, make the audio file pause or the volume reduction of earphone present broadcast, after the audio file pause or the volume reduction of earphone present broadcast, through relevant separation, positioning algorithm can realize tracking location sound source, and keep tracking down, thereby guarantee that earphone wearer can in time notice the communication demand that external pronunciation initiated, improve the user and experience the use of earphone.
