[0024] See also Figure 1 , Figure 1 A schematic diagram of a flow chart of a method for detecting hole blockage in a voice device provided in an embodiment of the present invention.

[0025] like Figure 1 As shown, the method includes steps S101 to S104.

[0026] S101, pre-recording a designated detection sound emitted by a sound generating device without hole blockage by a sound receiving device without hole blockage to obtain standard sound data; In this step, the recorded standard sound data is used as a reference in the subsequent hole blockage detection process.

[0027] S102, controlling the sound receiving device to be tested to record the designated detection sound emitted by the sound producing device to be tested, and obtaining the sound data to be tested; In this step, the recorded sound data to be tested is used for comparative analysis with the standard sound data to determine whether the hole is blocked.

[0028] S103, calculating the sound similarity between the sound data to be tested and the standard sound data, and when the sound similarity reaches a preset similarity threshold, determining that there is no hole blockage in the sound receiving device and the sound producing device to be tested.

[0029] S104, pre-recording a designated detection sound emitted by a sound-generating device through a sound receiving device to obtain blocked sound data, wherein at least one of the sound receiving device and the sound generating device has a blocked hole; calculating the sound similarity between the sound data to be tested and the blocked sound data, and determining that at least one of the sound receiving device and the sound generating device to be tested has a blocked hole when the sound similarity reaches a preset similarity threshold.

[0030] In this embodiment, based on the process of steps S101 to S104, by analyzing and comparing the sound data to be tested with the standard sound data, the sound similarity between the two can be calculated. Specifically, a sound similarity algorithm can be used to evaluate the similarity between the two sound samples. When the calculated sound similarity reaches the preset similarity threshold, it can be concluded that the sound receiving device and the sound producing device to be tested are not blocked. Similarly, by analyzing and comparing the sound data to be tested with the blocked sound data, specifically, a sound similarity algorithm can be used to evaluate the similarity between the two sound samples. When the calculated sound similarity reaches the preset similarity threshold, it can be concluded that at least one of the sound receiving device and the sound producing device to be tested is blocked. This detection method is efficient, simple, and can accurately identify whether there is a hole blockage problem, so that the user can be reminded to clean it in time when there is a hole blockage problem, thereby ensuring the normal operation of the voice device and the stability of the sound quality.

[0031] In this embodiment, in the process of hole blockage detection, in order to prevent the sound receiving device from being affected by human voice or other language devices when recording sound, the problem can be solved by recording a specified detection sound. Specifically, after the designated detection sound (such as a command word of a specified duration) is emitted by the control sound producing device, the sound is immediately recorded by the sound receiving device and sent to the processor, and the recorded sound is filtered by the processor to extract sound data with the same length and command word as the designated detection sound and use it as the sound data to be tested. In this way, it can be ensured that the sound data to be tested is emitted by the sound producing device.

[0032] In the present invention, in order to avoid the influence of recording and recognition between the sound producing device and the sound receiving device, for example, when there is a hole blockage in one of the sound producing device and the sound receiving device, the recorded sound cannot clearly tell whether the hole blockage occurs in the sound producing device or the sound receiving device. Therefore, it is necessary to achieve more accurate hole blockage judgment, and it is necessary to perform targeted detection design on the sound producing device and the sound receiving device respectively. The specific targeted detection design is shown in the specific plan of step S104 below.

[0033] like Figure 2 As shown, step S104 includes: S201, pre-recording a designated detection sound emitted by a sound generating device with a blocked hole by a sound receiving device without a blocked hole, to obtain first blocked sound data; S202, calculating the sound similarity between the sound data to be tested and the first blocking sound data; S203: When the sound similarity reaches a preset similarity threshold, it is determined that the sound generating device to be tested has a hole blockage.

[0034] This embodiment is a specific solution for detecting whether the opening of the sound device is blocked. The opening of the sound device can be blocked by dust or other blockages, and then the sound device with blocked openings is controlled to emit a designated detection sound, and the sound receiving device without blocked openings records the designated detection sound, thereby obtaining the first blocked sound data. Based on this, when the sound similarity between the sound data to be tested and the first blocked sound data reaches a preset similarity threshold, it is specifically determined that the sound device to be tested has blocked openings.

[0035] like Figure 3 As shown, step S104 includes: S301, pre-recording a designated detection sound emitted by a sound generating device without hole blockage by a sound receiving device with hole blockage, to obtain second blockage sound data; S302, calculating the sound similarity between the sound data to be tested and the second blocking sound data; S303: When the sound similarity reaches a preset similarity threshold, it is determined that the sound receiving device to be tested has a hole blockage.

[0036] This embodiment is a specific solution for detecting whether the sound receiving device has a hole blockage. The opening of the sound receiving device can be blocked by dust or other blockages, and then the sound generating device without hole blockage can be controlled to emit a designated detection sound, and the sound receiving device with hole blockage can record the designated detection sound, thereby obtaining the second blocking sound data. Based on this, when the sound similarity between the sound data to be tested and the second blocking sound data reaches a preset similarity threshold, it is specifically determined that the sound receiving device to be tested has a hole blockage.

[0037] like Figure 4 As shown, step S104 includes: S401, pre-recording a designated detection sound emitted by a sound generating device with a blocked hole by a sound receiving device with a blocked hole, to obtain third blocked sound data; S402, calculating the sound similarity between the sound data to be tested and the third blocking sound data; S403: When the sound similarity reaches a preset similarity threshold, it is determined that both the sound receiving device and the sound producing device to be tested have hole blockage.

[0038] This embodiment is a specific solution for detecting whether the sound receiving device and the sound producing device have blocked holes at the same time. The openings of the sound receiving device and the sound producing device can be blocked by dust or other blockages, and then the sound producing device with blocked holes can be controlled to emit a designated detection sound, and the sound receiving device with blocked holes can record the designated detection sound, thereby obtaining the third blocked sound data. Based on this, when the sound similarity between the sound data to be tested and the third blocked sound data reaches a preset similarity threshold, it is specifically determined that the sound receiving device and the sound producing device to be tested both have blocked holes.

[0039] like Figure 5 As shown, step S101 includes: S501, pre-recording a designated detection sound emitted by a sound generating device without hole blockage by a sound receiving device without hole blockage; S502: Perform acoustic-electrical signal conversion processing on the recorded designated detection sound to obtain the corresponding standard electrical signal frequency and standard amplitude, and generate standard sound data.

[0040] In this embodiment, after the designated detection sound is recorded, the sound signal of the designated detection sound needs to be converted into an acoustic-electrical signal. This process includes converting the sound signal into an electrical signal, and further analyzing the frequency and amplitude of these electrical signals to obtain the corresponding standard electrical signal frequency and standard amplitude. Finally, we organize and generate these data to form a set of standard sound data for subsequent comparison and analysis.

[0041] like Figure 6 As shown, step S102 includes: S601, controlling the sound receiving device to be tested to record a designated detection sound emitted by the sound producing device to be tested; S602: Perform acoustic-electrical signal conversion processing on the recorded designated detection sound to obtain the corresponding frequency and amplitude of the electrical signal to be tested, and generate the sound data to be tested.

[0042] In this embodiment, it is first necessary to control the sound receiving device to be tested so that it can accurately record the specified detection sound emitted by the sound generating device to be tested. Next, after recording the specified detection sound, it is necessary to perform an acoustic-electrical signal conversion process on the sound signal of the recorded specified detection sound. This process includes converting the sound signal into an electrical signal, and further analyzing the frequency and amplitude of these electrical signals to obtain the corresponding electrical signal frequency to be tested and the amplitude to be tested. Finally, we organize and generate these data to form the sound data to be tested, so as to compare and analyze them with the aforementioned standard sound data.

[0043] like Figure 7 As shown, step S103 includes: S701, calculating the frequency deviation value between the frequency of the electrical signal to be tested and the frequency of the standard electrical signal; S702, calculating the amplitude deviation between the amplitude to be measured and the standard amplitude; S703. When the frequency deviation value and the amplitude deviation value are both smaller than the corresponding preset deviation values, it is determined that the sound similarity between the sound data to be tested and the standard sound data reaches a preset similarity threshold, and it is determined that neither the sound receiving device nor the sound producing device to be tested has hole blockage.

[0044] In this embodiment, the frequency and amplitude of the electrical signal are two important parameters of the sound. The frequency deviation value and the amplitude deviation value obtained by steps S701 and S702, the larger the frequency deviation value and the amplitude deviation value, the smaller the sound similarity between the sound data to be tested and the standard sound data; if the frequency deviation value and the amplitude deviation value are both smaller than the corresponding preset deviation values ​​(that is, within an acceptable range), the sound similarity is large, indicating that the device is working normally and there is no hole blockage.

[0045] Furthermore, two preset deviation values ​​can be set, which are used to compare with the frequency deviation value and the amplitude deviation value respectively. When the frequency deviation value and the amplitude deviation value are both within the corresponding preset deviation values, the sound similarity between the sound data to be tested and the standard sound data reaches the preset similarity threshold, and it can be determined that the sound receiving device and the sound producing device to be tested have no hole blockage. On the contrary, if at least one of the frequency deviation value and the amplitude deviation value is greater than the corresponding preset deviation value, it is determined that at least one of the sound receiving device and the sound producing device to be tested has a hole blockage.

[0046] Similarly, it can be understood that when the sound data to be tested is compared with the first blocked sound data, the second blocked sound data or the third blocked sound data for sound similarity, the sound similarity principle of steps S701 to S703 is also adopted. For example, when the sound data to be tested is compared with the first blocked sound data for sound similarity, when the frequency deviation value and the amplitude deviation value are both less than the corresponding preset deviation values, it is determined that the sound similarity between the sound data to be tested and the first blocked sound data reaches the preset similarity threshold, and it is determined that the sound device to be tested has hole blockage.

[0047] In one embodiment, the voice device hole blockage detection method further includes: Obtain the testing environment and equipment aging degree of the sound receiving device and sound producing device; Adjusting the preset similarity threshold according to the interference degree of the detection environment, wherein the greater the interference degree of the detection environment, the more the preset similarity threshold is lowered; The preset similarity threshold is adjusted according to the aging degree of the sound receiving device and the sound producing device, wherein the greater the aging degree of the device, the more the preset similarity threshold is adjusted downward.

[0048] In this embodiment, the interference degree of the detection environment mainly refers to the environmental noise value. The greater the environmental noise value, the higher the interference degree of the detection environment. The equipment aging degree mainly refers to the service life of the equipment. The longer the service life, the higher the equipment aging degree.

[0049] The embodiment of the present invention further provides a voice device hole blocking detection device, which is used to execute any embodiment of the voice device hole blocking detection method. Figure 8 , Figure 8 It is a schematic block diagram of a voice device hole blocking detection device provided by an embodiment of the present invention.

[0050] like Figure 8 As shown, the voice equipment hole blocking detection device 800 includes: a first recording unit 801, a second recording unit 802, a first hole blocking determination unit 803, a third recording unit 804 and a second hole blocking determination unit 805; The first recording unit 801 is used to record the designated detection sound emitted by the sound generating device without hole blockage in advance through the sound receiving device without hole blockage to obtain standard sound data; The second recording unit 802 is used to control the sound receiving device to be tested to record the specified detection sound emitted by the sound generating device to be tested, and obtain the sound data to be tested; The first hole blocking determination unit 803 is used to calculate the sound similarity between the sound data to be tested and the standard sound data, and when the sound similarity reaches a preset similarity threshold, it is determined that there is no hole blocking in the sound receiving device and the sound producing device to be tested; The third recording unit 804 is used to record the designated detection sound emitted by the sound generating device in advance through the sound receiving device to obtain the blocking sound data, wherein at least one of the sound receiving device and the sound generating device has a hole blocking; The second hole blocking determination unit 805 is used to calculate the sound similarity between the sound data to be tested and the blocked sound data, and when the sound similarity reaches a preset similarity threshold, it is determined that at least one of the sound receiving device and the sound producing device to be tested has a blocked hole.

[0051] The device can calculate the sound similarity between the sound data to be tested and the standard sound data by analyzing and comparing them. Specifically, a sound similarity algorithm can be used to evaluate the similarity between the two sound samples. When the calculated sound similarity reaches a preset similarity threshold, it can be concluded that neither the sound receiving device nor the sound producing device to be tested has a hole blockage. Similarly, by analyzing and comparing the sound data to be tested with the blocked sound data, specifically, a sound similarity algorithm can be used to evaluate the similarity between the two sound samples. When the calculated sound similarity reaches a preset similarity threshold, it can be concluded that at least one of the sound receiving device and the sound producing device to be tested has a hole blockage. This detection method is efficient, simple, and can accurately identify whether there is a hole blockage problem, so that the user can be reminded to clean it in time when there is a hole blockage problem, thereby ensuring the normal operation of the voice device and the stability of the sound quality.
