Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the embodiments and drawings of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
The embodiment of the invention discloses a reverberation adjusting method and electronic equipment, which can improve the efficiency of adjusting reverberation and reduce the technical threshold. The following are detailed below.
Example one
Referring to fig. 1, fig. 1 is a flowchart illustrating a reverberation adjustment method according to an embodiment of the present invention. The reverberation adjustment method described in fig. 1 is suitable for electronic devices such as mobile phones and tablet computers that can establish a communication connection with a microphone device, and the embodiment of the present invention is not limited thereto. The operating system of the electronic device may include, but is not limited to, an Android operating system, an IOS operating system, a Symbian operating system, a blackberry operating system, a Windows Phone8 operating system, and the like. As shown in fig. 1, the reverberation adjustment method may include the steps of:
101. the electronic equipment receives any target sound signal collected by the microphone equipment and extracts the target sound characteristics of the target sound signal.
In the embodiment of the invention, the microphone device can have a recording function, after the microphone device collects any sound signal under the condition that the recording function is started, the sound signal can be stored as a target sound signal and sent to the electronic device, and the microphone device can also transmit the target sound signal to the electronic device in a data stream mode so as to realize real-time transmission of the target sound signal. In addition, the communication connection between the electronic device and the microphone device may be a wired connection, or a wireless connection such as a bluetooth connection or a Wi-Fi connection, which is not limited in the embodiment of the present invention.
In practical applications, the target sound signal received by the electronic device may include a sound recorded by a user during speaking and may also include noise of the surrounding environment due to various interferences, and therefore, in order to reduce the influence of the noise interferences on subsequent matching of the sound features, the electronic device may perform preprocessing on the target sound signal after receiving the target sound signal and before extracting the sound features of the target sound signal. The preprocessing method may include, but is not limited to, pre-emphasis, end point detection, framing, windowing, and denoising, and the embodiments of the present invention are not limited thereto. By preprocessing the target sound signal, the accuracy of user identity recognition can be improved.
In addition, because the structure of each pronunciation organ is different, and each person's sound is different in sound physical properties such as tone quality, duration, intensity or pitch, therefore, can carry out user identification through the sound characteristic. The target sound feature extracted from the target sound signal by the electronic device may be one or more of the above-mentioned sound physical attributes, and the embodiment of the present invention is not limited.
102. The electronic device judges whether the target sound characteristic is matched with any preset sample sound characteristic, if so, the steps 103-104 are executed, and if not, the step 105 is executed.
In the embodiment of the invention, Mel-scale Frequency Cepstral Coefficients (MFCC for short) can be used as the parameter for representing the sound characteristics.
Optionally, when the electronic device determines whether the target sound feature matches any preset sample sound feature, a template matching method may be used to calculate a distance between each sample sound feature of all preset sample sound features and the target sound feature, and determine whether the distance between the two sample sound features is smaller than a specified threshold, and if the distance between any sample sound feature and the target sound feature is smaller than the specified threshold, it may be considered that the target sound feature matches the sample sound feature; if the distance between one sample sound feature and the target sound feature is not smaller than the specified threshold in all the sample sound features, the target sound feature may be considered to be not matched with any preset sample sound feature, that is, the electronic device cannot identify the user identity through the target sound feature.
Further optionally, when the electronic device determines that the target sound feature matches the sample sound feature, the electronic device may further adjust the sample sound feature by using the target sound feature to optimize the sample sound feature and improve the accuracy of the identification.
103. And the electronic equipment searches the target user identity corresponding to the sample sound characteristics.
In the embodiment of the invention, the target user identity is one of at least two preset user identities. For example, the user identities may be divided into five different identities of children, mom, dad, grande/grande, etc. according to the user age, or may be divided into two identities of males and females according to the age, which is not limited in the embodiment of the present invention. In the preset sample sound characteristics of the electronic equipment, each sample sound characteristic is bound with one user identity, so that when the electronic equipment judges that the target sound characteristics are matched with any preset sample sound characteristics, the target user identity corresponding to the sample sound characteristics can be found through the binding relation between the sample sound characteristics and the user identities, and the user identities are identified.
104. And the electronic equipment adjusts the current reverberation scheme to be the user reverberation scheme corresponding to the target user identity.
In the embodiment of the invention, the electronic equipment can preset the reverberation scheme corresponding to each user identity, and the reverberation scheme corresponding to each user identity is different. For example, for a reverberation scheme corresponding to the user identity of the child, the reverberation time of the reverberation scheme can be longer than that of other reverberation schemes, and can be extended to 1.5 ms.
105. The electronics adjust the current reverberation scheme to a default reverberation scheme.
In the embodiment of the present invention, the default reverberation scheme is different from all the reverberation schemes corresponding to the at least two user identities.
Optionally, if the electronic device determines that the target sound signal does not match any preset sample sound signal, the electronic device may further determine a pitch of the target sound signal by analyzing a frequency of the target sound signal, and adjust the current reverberation scheme to a reverberation scheme corresponding to the pitch of the target sound signal. For example, the electronic device analyzes that the occupation ratio of the low-frequency signal with the frequency lower than the specified frequency value in the target sound signal is higher than the specified threshold, and then the electronic device may consider the pitch of the target sound signal as bass and adjust the current reverberation scheme to the reverberation scheme corresponding to the bass. The reverberation time of the reverberation scheme corresponding to the bass may be shorter than the reverberation time of the default reverberation scheme, or the reverberation intensity of the reverberation scheme corresponding to the bass may be lower than the reverberation intensity of the default reverberation scheme, so as to improve the clarity of the sound.
It can be seen that, in the method described in fig. 1, the electronic device may identify a user identity through the target sound feature, and automatically adjust the current reverberation scheme to the user reverberation scheme corresponding to the user identity, without manually adjusting reverberation by the user, so that efficiency of adjusting reverberation may be improved, and a technical threshold of the user may be lowered. Further, in the method described in fig. 1, the electronic device may further adjust the current reverberation scheme to a default reverberation scheme in a case where the user identity cannot be recognized, or determine a pitch of the target sound signal by analyzing the frequency of the target sound signal, so as to adjust the current reverberation scheme to a reverberation scheme corresponding to the pitch of the target sound signal, so that the sound playing effect may be improved in a case where the user identity cannot be recognized.
Example two
Referring to fig. 2, fig. 2 is a flow chart illustrating another reverberation adjustment method according to an embodiment of the present invention. As shown in fig. 2, the reverberation adjustment method may include the steps of:
in the embodiment of the present invention, steps 201 to 205 are the same as steps 101 to 105, and the following description is omitted.
206. The electronic device detects the identity setting instruction.
In the embodiment of the present invention, the identity setting instruction is used to set any one of the at least two user identities, and the identity setting instruction may carry user identity information that needs to be set by the identity setting instruction.
As an alternative embodiment, the electronic device may detect the identity setting instruction by detecting a click event occurring on a screen of the electronic device, and if the occurrence location of the click event is a location bound to any user identity, the electronic device may determine that the identity setting instruction is detected, and the identity setting instruction is used to set any user identity.
As another optional implementation, the electronic device may also detect voice information input by a user, where the voice information may be a sound signal collected by a microphone device and sent to the electronic device, or a sound signal collected by a microphone device carried by the electronic device, and the embodiment of the present invention is not limited thereto. After the electronic device detects the voice information, the electronic device may perform voice recognition on the voice information, when the voice information is recognized to include preset keywords such as "identity" and "setting", the electronic device may determine that an identity setting instruction is detected, and if the keywords recognized by the electronic device from the voice information include preset user identities such as "child" or "male", the electronic device may use the user identity recognized from the keywords as the user identity information carried by the identity setting instruction. Therefore, the electronic equipment acquires the user identity information in a voice recognition mode, and the user does not need to directly operate the screen of the electronic equipment, so that the operation steps of the user are simplified.
As another alternative implementation, the electronic device may further start a front-facing camera on the same side as a screen of the electronic device to capture an image, and determine whether the captured image is a human face image, and if the captured image is a human face image, the electronic device may determine that the identity setting instruction is detected. In addition, the electronic equipment can also analyze the face image, extract the identity characteristics such as age characteristics or sex characteristics of the face image, and recognize the user identity of the user as the user identity information carried by the identity setting instruction according to the identity characteristics, so that the probability that the user identity information acquired by the electronic equipment is consistent with the actual identity information of the user can be improved.
207. The electronic equipment receives the user voice signal collected by the microphone equipment according to the identity setting instruction, and extracts the user voice feature of the user voice signal.
208. The electronic device stores the user voice signature as a sample voice signature corresponding to any of the user identities described above.
In the embodiment of the present invention, before the electronic device stores the user sound feature as the sample sound feature corresponding to any user identity, the electronic device may further determine whether a sample sound feature matching the user sound feature exists in all sample sound features corresponding to the user identity, if so, adjust the sample sound feature matching the user sound feature by using the user sound feature, and if not, store the user sound as the sample sound feature corresponding to the user identity, so that the sample sound feature database may be updated and adjusted.
Furthermore, for convenience of description, in the embodiment of the present invention, step 206 may be performed after step 205. It should be noted that there is no logical precedence relationship between step 206 and step 205, and step 206 may be executed before step 205 or after step 205, which is not limited in the embodiments of the present invention.
As can be seen, in the method described in fig. 2, the electronic device may identify the target user identity by matching the target sound feature and the sample sound feature, and adjust the current reverberation scheme to the reverberation scheme corresponding to the target user identity, so as to improve the efficiency of reverberation adjustment and reduce the technical threshold of the user. In addition, after the identity setting instruction is detected, the electronic device can store the user voice feature as a sample voice feature corresponding to the user identity, so that the sample voice feature database can be updated and adjusted. In the method described in fig. 2, the manner in which the electronic device detects the identity setting instruction may be to detect a click event occurring on a screen of the electronic device; furthermore, the mode of the electronic equipment for detecting the identity setting instruction can also be voice recognition on the collected voice information, so that a user does not need to directly operate a screen of the electronic equipment, and the operation steps of the user are simplified; furthermore, the mode of the electronic device for detecting the identity setting instruction may also be that a front-facing camera is started to collect an image, and the identity feature included in the face image is extracted as the user identity information under the condition that the collected image is the face image, so that the probability that the user identity information acquired by the electronic device is consistent with the actual identity information of the user can be improved.
EXAMPLE III
Referring to fig. 3, fig. 3 is a flow chart illustrating another reverberation adjustment method according to an embodiment of the present invention. As shown in fig. 3, the reverberation adjustment method may include the steps of:
301. the electronic device detects the identity setting instruction.
In the embodiment of the present invention, the identity setting instruction is used to set any one of the at least two user identities.
302. The electronic device determines whether a communication connection has been established between the electronic device and the microphone device, and if so, directly performs step 305, and if not, performs steps 303 to 304.
303. And the electronic equipment outputs prompt information.
In the embodiment of the present invention, the prompt information is used to prompt a user to establish a communication connection between the electronic device and the microphone device, and the prompt information may be output through a screen of the electronic device in the form of text information, may also be output through a speaker device of the electronic device in the form of voice information, and may also be sent from the electronic device to the microphone device in the form of voice information, and the voice information is played through the microphone device. By outputting the prompt information, the probability of failure in user identity setting caused by the fact that communication connection is not established between the electronic equipment and the microphone equipment can be reduced, and user experience is improved.
304. The electronic equipment detects a communication connection instruction input by a user aiming at the prompt information, and establishes communication connection between the electronic equipment and the microphone equipment according to the communication connection instruction.
305. The electronic equipment sends a playing instruction to the microphone equipment so as to enable the microphone equipment to play the test sound content.
In the embodiment of the invention, the test sound content played by the microphone device is used for guiding the user to input the user sound signal containing the specified content. The content of the test tone played by the microphone device can be different according to the different user identity information carried by the identity setting instruction. For example, if the user is a child, the microphone device may play a test tone with "a child, please follow me, you good! Therefore, appropriate guidance can be provided in the process of setting the user identity of the user, and the technical threshold of the user is further reduced.
306. The electronic device detects whether a feedback instruction is received, if so, the steps 307 to 308 are executed, and if not, the step 309 is directly executed.
In the embodiment of the invention, the feedback instruction is sent by the microphone equipment when the playing of the test sound content is finished.
307. The electronic equipment receives the user voice signal collected by the microphone equipment according to the identity setting instruction, and extracts the user voice feature of the user voice signal.
308. The electronic device stores the user voice signature as a sample voice signature corresponding to any user identity.
In the embodiment of the present invention, the electronic device executes the above steps 301 to 308, so as to complete the setting of the user identity, add a new sample sound feature to the sample sound feature database, and establish a corresponding relationship between the new sample sound feature and the user identity.
309. The electronic equipment receives any target sound signal collected by the microphone equipment and extracts the target sound characteristics of the target sound signal.
310. The electronic device determines whether the target sound characteristic matches any preset sample sound characteristic, and if so, executes steps 311-312, and if not, executes step 313.
311. And the electronic equipment searches the target user identity corresponding to the sample sound characteristics.
312. And the electronic equipment adjusts the current reverberation scheme to be the user reverberation scheme corresponding to the target user identity.
313. The electronics adjust the current reverberation scheme to a default reverberation scheme.

Further, in the method described in fig. 3, the electronic device may output a prompt message to remind the user when the electronic device and the microphone device do not establish a communication connection, so that the probability of the user identity setting failure due to the fact that the communication connection is not established between the electronic device and the microphone device may be improved, and the user experience may be improved. Furthermore, in the method described in fig. 3, the electronic device may further send a play instruction to enable the microphone device to play the test tone content for guiding the user, so that appropriate guidance may be provided in the process of setting the user identity by the user, thereby further reducing the technical threshold of the user.

in the embodiment of the present invention, the default reverberation scheme is different from all the reverberation schemes corresponding to the at least two user identities;
as an alternative embodiment, if the first determining unit 402 determines that the target sound signal does not match any preset sample sound signal, the adjusting unit 404 may further determine a pitch of the target sound signal by analyzing a frequency of the target sound signal, and adjust the current reverberation scheme to a reverberation scheme corresponding to the pitch of the target sound signal; for example, the adjusting unit 404 analyzes that the low-frequency signal with the frequency lower than the first specified threshold has a larger proportion in the target sound signal, and then the pitch of the target sound signal can be considered as a bass, and the adjusting unit 404 adjusts the current reverberation scheme to the reverberation scheme corresponding to the bass; the reverberation time of the reverberation scheme corresponding to the bass may be shorter than the reverberation time of the default reverberation scheme, or the reverberation intensity of the reverberation scheme corresponding to the bass may be lower than the reverberation intensity of the default reverberation scheme, so as to improve the clarity of the sound.
