The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0050] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the sound signal determination device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0051] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a sound signal determination program.

[0052] exist Figure 1 In the sound signal determination device shown, the network interface 1004 is mainly used for data communication with the network integration platform workstation; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the sound signal determination device of the present invention can be set in the sound signal determination device, and the sound signal determination device calls the sound signal determination program stored in the memory 1005 through the processor 1001, and executes the sound signal determination method provided by the embodiment of the present invention.

[0053] Based on the above hardware structure, an embodiment of a method for determining a sound signal of the present invention is proposed.

[0054] Reference Figure 2 , Figure 2 FIG. 1 is a flow chart of a first embodiment of a method for determining a sound signal according to the present invention.

[0055] In a first embodiment, the sound signal determination method comprises the following steps:

[0056] Step S10, when the decibel value corresponding to the left noise signal and the decibel value corresponding to the right noise signal are both inconsistent with the preset decibel threshold, the gain of the sound receiving device is adjusted.

[0057] It should be noted that the executor of this embodiment is a sound signal determination device, and may also be other devices that can achieve the same or similar functions, such as smart devices, etc. This embodiment does not limit this. In this embodiment, smart devices are used as an example for explanation.

[0058] It should be understood that reference Figure 3 , Figure 3 Schematic diagram of the module position of the smart device, specifically: two symmetrical omnidirectional noise monitoring devices are arranged at the hinges of the temples of the smart device, for example, microphone 1 and microphone 2, and the holes of microphone 1 and microphone 2 are oriented to the outside of the temples and are perpendicular to the temples, and two symmetrical sound receiving devices are arranged on the underside of the lens of the smart device, for example, microphone 3 and microphone 4, and the holes of microphone 3 and microphone 4 are oriented to the inside, that is, the direction of wearing the smart device.

[0059] It can be understood that the left noise signal is monitored by microphone 1, and the right noise signal is monitored by microphone 2. When the user wears the smart device, the noise signals monitored by microphone 1 and microphone 2 are different. After obtaining the left noise signal and the right noise signal, it is determined whether the decibel value corresponding to the left noise signal and the decibel value corresponding to the right noise signal are consistent with the preset decibel threshold. If not, the gain of the sound receiving device is adjusted. There are two situations in which the decibel value corresponding to the left noise signal and the decibel value corresponding to the right noise signal are consistent with the preset decibel threshold, namely, the decibel value corresponding to the left noise signal is greater than the preset decibel threshold and the decibel value corresponding to the right noise signal is less than the preset decibel threshold, and the decibel value corresponding to the left noise signal is less than the preset decibel threshold and the decibel value corresponding to the right noise signal is greater than the preset decibel threshold.

[0060] Further, step S10 includes: when the decibel value corresponding to the left noise signal is greater than a preset decibel threshold and the decibel value corresponding to the right noise signal is less than the preset decibel threshold, obtaining the current gain of the left radio device and the current gain of the right radio device; reducing the current gain of the left radio device and increasing the current gain of the right radio device.

[0061] It can be understood that when it is determined that the decibel value corresponding to the left noise signal is greater than the preset decibel threshold and the decibel value corresponding to the right noise signal is less than the preset decibel threshold, it indicates that the noise on the left is louder than the noise on the right. At this time, it is necessary to reduce the current gain of the left radio device and increase the current gain of the right radio device. Through the above-mentioned gain adjustment, the other device receiving the target sound signal will not have the defect of large noise signal on one side and small noise signal on the other side.

[0062] Furthermore, after reducing the current gain of the left radio device and increasing the current gain of the right radio device, the method also includes: picking up a first left sound signal by the left radio device after adjusting the gain, and picking up a first right sound signal by the right radio device after adjusting the gain; calculating the difference between the decibel value corresponding to the left noise signal and a preset decibel threshold; performing noise reduction on the left noise signal and the right noise signal according to the difference between the decibel value corresponding to the left noise signal and the preset decibel threshold; and when the decibel value corresponding to the left noise signal after noise reduction is equal to the preset decibel threshold, mixing the first left sound signal and the first right sound signal to obtain a target sound signal.

[0063] It should be understood that after adjusting the gains of the left and right radio devices, the first left sound signal is picked up by the left radio device after the gain is adjusted and the first right sound signal is picked up by the right radio device after the gain is adjusted, and then noise reduction is performed. Specifically, the difference between the decibel value corresponding to the left noise signal and the preset decibel threshold is calculated, and the left noise signal is noise reduced according to the difference between the decibel value corresponding to the left noise signal and the preset decibel threshold, that is, the decibel value corresponding to the left noise signal is reduced to the preset decibel threshold, and the right noise signal is also noise reduced according to the difference, and then the first left sound signal picked up by the left radio device after the gain is adjusted and the first right sound signal picked up by the right radio device after the gain is adjusted are mixed to obtain the target sound signal, thereby effectively improving the clarity of the sound and reducing the impact of noise while retaining the sound signal of the user's speech.

[0064] Further, step S10 includes: when the decibel value corresponding to the left noise signal is less than a preset decibel threshold and the decibel value corresponding to the right noise signal is greater than the preset decibel threshold, obtaining the current gain of the left radio device and the current gain of the right radio device; increasing the current gain of the left radio device and reducing the current gain of the right radio device.

[0065] It can be understood that when it is determined that the decibel value corresponding to the left noise signal is less than the preset decibel threshold and the decibel value corresponding to the right noise signal is greater than the preset decibel threshold, it indicates that the noise on the right is louder than the noise on the left. At this time, it is necessary to increase the current gain of the left radio device and reduce the current gain of the right radio device. Through the above-mentioned gain adjustment, the other device receiving the target sound signal will not have the defect of large noise signal on one side and small noise signal on the other side.

[0066] Furthermore, after increasing the current gain of the left radio device and reducing the current gain of the right radio device, the method further includes: picking up a second left sound signal through the adjusted left radio device and picking up a second right sound signal through the adjusted right radio device; calculating the difference between the decibel value corresponding to the right noise signal and a preset decibel threshold, and performing noise reduction on the right noise signal and the left noise signal according to the difference between the decibel value corresponding to the right noise signal and the preset decibel threshold; when the decibel value corresponding to the right noise signal after noise reduction is equal to the preset decibel threshold, mixing the second left sound signal and the second right sound signal to obtain a target sound signal.

[0067] It should be understood that after increasing the gains of the left and right radio devices, the second left sound signal is picked up by the left radio device after the gain is adjusted and the second right sound signal is picked up by the right radio device after the gain is adjusted, and then noise reduction is performed. Specifically, the difference between the decibel value corresponding to the right noise signal and the preset decibel threshold is calculated, and the right noise signal is noise reduced according to the difference between the decibel value corresponding to the right noise signal and the preset decibel threshold, that is, the decibel value corresponding to the right noise signal is reduced to the preset decibel threshold, and the left noise signal is also noise reduced according to the difference, and then the second left sound signal picked up by the left radio device after the gain is adjusted and the second right sound signal picked up by the right radio device after the gain is adjusted are mixed to obtain the target sound signal, thereby effectively improving the clarity of the sound and reducing the impact of noise while retaining the sound signal of the user's speech.

[0068] Step S20, obtaining the current sound signal through the sound receiving device after adjusting the gain.

[0069] It is understandable that the current sound signal refers to the sound signal monitored by the sound receiving device after adjusting the gain. Since there are multiple sound receiving devices, there are also multiple sound signals monitored by the sound receiving devices, for example, a left sound signal and a right sound signal.

[0070] Step S30: performing noise reduction on the left noise signal and the right noise signal.

[0071] It should be understood that after obtaining the left noise signal and the right noise signal, the left noise signal and the right noise signal are denoised according to the difference between the decibel value corresponding to the left noise signal and the preset decibel threshold or the difference between the corresponding decibel value and the preset decibel threshold.

[0072] Step S40: determining a target sound signal according to the denoised left noise signal, the denoised right noise signal and the current sound signal.

[0073] It can be understood that the target sound signal refers to a sound signal used to be transmitted to the other party's device, and the clarity of the sound corresponding to the target sound signal is extremely high.

[0074] Further, step S40 includes: when the decibel value corresponding to the left noise signal is greater than the decibel value corresponding to the right noise signal and the decibel value corresponding to the left noise signal after noise reduction is equal to a preset decibel threshold, or when the decibel value corresponding to the right noise signal is greater than the decibel value corresponding to the left noise signal and the decibel value corresponding to the right noise signal after noise reduction is equal to the preset decibel threshold, mixing the left sound signal and the right sound signal to obtain a target sound signal.

[0075] It should be understood that after the left noise signal and the right noise signal are denoised, if the decibel value corresponding to the left noise signal is greater than the decibel value corresponding to the right noise signal and the decibel value corresponding to the left noise signal after denoising is equal to the preset decibel threshold, then the decibel value corresponding to the right noise signal after denoising must be less than the preset decibel threshold; if the decibel value corresponding to the right noise signal is greater than the decibel value corresponding to the left noise signal and the decibel value corresponding to the right noise signal after denoising is equal to the preset decibel threshold, then the decibel value corresponding to the left noise signal after denoising must be less than the preset decibel threshold. At this time, the left sound signal and the right sound signal are mixed to obtain the target sound signal.

[0076] This embodiment adjusts the gain of the sound receiving device when the decibel value corresponding to the left noise signal and the decibel value corresponding to the right noise signal are inconsistent with the preset decibel threshold; obtains the current sound signal through the sound receiving device after the gain is adjusted; performs noise reduction on the left noise signal and the right noise signal; determines the target sound signal according to the left noise signal after noise reduction, the right noise signal after noise reduction and the current sound signal; through the above manner, when the decibel value corresponding to the noise signal is inconsistent with the preset decibel threshold, adjusts the gain of the sound receiving device, then performs noise reduction on the left noise signal and the right noise signal, and then mixes the sound signal obtained by the sound receiving device after the gain is adjusted, thereby effectively reducing the influence of noise on the sound signal, thereby improving the clarity of the transmitted sound.

[0077] In one embodiment, if Figure 4 The second embodiment of the sound signal determination method of the present invention is proposed based on the first embodiment. After step S40, the method further includes:

[0078] Step S501: when a sound signal adjustment request is received, the target sound signal is adjusted according to the sound signal adjustment request, and the adjusted target sound signal is transmitted.

[0079] It should be understood that a sound signal adjustment request refers to a request for adjusting a sound signal. The object of the sound signal adjustment request may be a user wearing a smart device or a counterpart device. When the object is a counterpart device and the user uses the smart device to make a call, the sound signal adjustment request may be "The sound is too quiet and a little unclear. Please speak a little louder."

[0080] Step S502: determining the noise decibel threshold value preferred by the user according to the adjusted target sound signal.

[0081] It can be understood that the noise decibel threshold preferred by the user refers to the noise decibel threshold preferred by the user according to his or her own habits, and the noise decibel threshold is determined according to the adjusted target sound signal using a machine learning algorithm.

[0082] Step S503: updating the preset decibel threshold by using the noise decibel threshold.

[0083] It should be understood that after obtaining the noise decibel threshold preferred by the user, the preset decibel threshold is updated by the noise decibel threshold, that is, the object used for comparison with the decibel value corresponding to the noise signal next time is the noise decibel threshold preferred by the user, and the noise decibel threshold preferred by the user is continuously updated in real time.

[0084] Understandably, reference Figure 5 , Figure 5: is a schematic diagram of the overall process, specifically: after setting the preset decibel threshold N, if it is determined that the decibel value corresponding to the left noise signal is greater than the preset decibel threshold N and the decibel value corresponding to the right noise signal is less than the preset decibel threshold N, the current gain of the left radio device is reduced, and the current gain of the right radio device is increased. At this time, the small sound signal of the left radio device after the gain is adjusted will be amplified, and the large sound signal will be reduced, while the large sound signal of the right radio device after the gain is adjusted will be amplified, and the small sound signal will be reduced. Then, the left noise signal and the right noise signal are noise-reduced at the same time, and then the first left sound signal picked up by the adjusted left radio device and the first right sound signal picked up by the adjusted right radio device are mixed to obtain the target sound signal. If it is determined that the decibel value corresponding to the left noise signal is less than the preset decibel threshold N and the decibel value corresponding to the right noise signal is greater than the preset decibel threshold N, then Increase the current gain of the left radio device, and decrease the current gain of the right radio device. At this time, the loud sound signal of the left radio device after the gain is adjusted will be amplified, and the small sound signal will be reduced, while the small sound signal of the right radio device after the gain is adjusted will be amplified, and the loud sound signal will be reduced. Then, the left noise signal and the right noise signal are noise reduced at the same time, and then the first left sound signal picked up by the adjusted left radio device and the first right sound signal picked up by the adjusted right radio device are mixed to obtain the target sound signal, and then the target sound signal is transmitted. When a sound signal adjustment request is received, the target sound signal is adjusted according to the sound signal adjustment request, and the adjusted target sound signal is transmitted, and the noise decibel threshold preferred by the user is determined according to the adjusted target sound signal, and then the preset decibel threshold N is updated by the noise decibel threshold.

[0085] This embodiment adjusts the target sound signal according to the sound signal adjustment request when a sound signal adjustment request is received, and transmits the adjusted target sound signal; determines the noise decibel threshold preferred by the user according to the adjusted target sound signal; and updates the preset decibel threshold through the noise decibel threshold. In the above manner, when a sound signal adjustment request is received, the target sound signal is adjusted according to the sound signal adjustment request, and then while transmitting the adjusted target sound signal, the noise decibel threshold preferred by the user is determined, and then the preset decibel threshold is updated through the noise decibel threshold, so that the noise decibel threshold that is compatible with the user preference can be updated in time, thereby improving the user experience.

[0086] In addition, an embodiment of the present invention further provides a storage medium, on which a sound signal determination program is stored. When the sound signal determination program is executed by a processor, the steps of the sound signal determination method described above are implemented.

[0087] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
