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 some, not all, embodiments of the present invention. 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.
Referring to fig. 1, fig. 1 is a flowchart of a pickup testing method according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
The sound pickup test method can be applied to sound pickup test equipment. The first playing device may be a device with a playing function, such as a computer or a sound box, and the first playing device may be a part of the sound pickup testing device, for example, the sound pickup testing device may be a computer, and the first playing device may be an external sound box of the sound pickup testing device; alternatively, the first playback device may be a separate device, such as a computer. The test audio file may be a preset audio file, and in order to adjust the playing setting parameters of the first playing device better, so as to improve the accuracy of the test result, the test audio file may include a preset signal, for example, the test audio file may include a chrip signal (chirp signal), and the chrip signal may be a signal whose instantaneous frequency changes with time within a certain range. In practical application, the test audio file may be a fixed-duration audio file, and the chrip signal is added to the beginning and the end of the audio file.
And 102, acquiring the voice characteristic parameters of the first test voice.
Wherein the voice feature parameter of the first test voice may be obtained based on the amplitude of the first test voice. Taking the first playing device as an example of a sound box, the sound box plays a test audio file, the device to be tested records, and collects a first test voice, for example, the first test voice may be an a.pcm audio file. The voice characteristic parameter of the first test voice may include a magnitude of each sampling point in the a.pcm audio file, or the voice characteristic parameter of the first test voice may be calculated based on the magnitude of each sampling point in the a.pcm audio file.
The reference voice characteristic parameter may be a voice characteristic parameter of a preset audio file, for example, the reference voice characteristic parameter may include a magnitude of each sampling point in the preset audio file, or the reference voice characteristic parameter may be obtained by calculation based on the magnitude of each sampling point in the preset audio file; or, a second test voice collected by the device to be tested can be obtained, the second test voice is the voice of the test audio file played by the second playing device collected by the device to be tested, and the voice characteristic parameter of the second test voice is obtained, wherein the reference voice characteristic parameter is the voice characteristic parameter of the second test voice.
In addition, in the case that the voice feature parameter of the first test voice includes the amplitude of each sampling point of the first test voice, and the reference voice feature parameter includes the amplitude of each sampling point in the preset audio file, the comparison result may be a curve comparison graph of the voice feature parameter of the first test voice and the reference voice feature parameter, for example, a first curve of the voice feature parameter of the first test voice with respect to time and a second curve of the reference voice feature parameter with respect to time may be drawn on the curve comparison graph; or, in the case that the voice feature parameter of the first test voice is a value calculated based on the amplitude of each sampling point in the first test voice, and the reference voice feature parameter is a value calculated based on the amplitude of each sampling point in a preset audio file, the comparison result may include a ratio of the voice feature parameter of the first test voice to the reference voice feature parameter.
and the equipment to be tested performs sound pickup test based on the adjusted playing setting parameters of the first playing equipment.
The playing setting parameter may include a playing volume, or may also include a reverberation value, or may also include superimposed noise, or the like. When the comparison result is a curve comparison graph of the voice characteristic parameter of the first test voice and the reference voice characteristic parameter, the comparison result does not satisfy a preset condition, where an amplitude difference corresponding to a certain time point between the first curve and the second curve is greater than a third preset value, and the third preset value may be 0.5dB, 2dB, or 3dB, and so on; when the comparison result includes a ratio of the speech feature parameter of the first test speech to the reference speech feature parameter, the comparison result does not satisfy a preset condition, which may be that the ratio is greater than a first preset value or the ratio is smaller than a second preset value, the first preset value is a positive number greater than or equal to 1, and the second preset value is a positive number less than or equal to 1. The first test voice collected by the equipment to be tested can be obtained for multiple times, and the playing setting parameters of the first playing equipment are adjusted for multiple times until the comparison result meets the preset condition. After the comparison result meets the preset condition, the device to be tested can perform pickup test based on the adjusted play setting parameter of the first playing device.
In addition, the comparison result may include a ratio of the voice feature parameter of the first test voice to the reference voice feature parameter, the playing setting parameter may include a playing volume, and adjusting the playing setting parameter of the first playing device based on the comparison result may include: if the ratio is larger than a first preset value, reducing the playing volume of the first playing device; and if the ratio is smaller than a second preset value, increasing the playing volume of the first playing device. The playing setting parameters of the first playing device can be adjusted for multiple times, and the first test voice collected by the device to be tested is obtained for multiple times until the comparison result is less than or equal to a first preset value and greater than or equal to a second preset value. The prompt message may include the comparison result, or the prompt message may include: and reducing the playing volume of the first playing device or increasing the playing volume of the first playing device.
Further, the acquiring of the first test voice collected by the device to be tested may be acquiring the first test voice collected by the device to be tested in the first test environment. The reference voice characteristic parameter may be a voice characteristic parameter of a second test voice collected by the device under test in a second test environment. The first playing device can be placed at a preset position under a first test environment. Before acquiring a first test voice collected by a device to be tested, the first test environment and the second test environment can be aligned, and the first test environment and the second test environment can be aligned by measuring a measurable value under the test environment, so that the basic environments of the first test environment and the second test environment are consistent. The measurable values may include a reverberation value, a distance, a decibel value, and the like, for example, the reverberation value of the room of the first test environment may be the same as the reverberation value of the room of the second test environment, the distance between the device under test and the playing device in the first test environment is the same as the distance between the device under test and the playing device in the second test environment, and the like. And aligning the first test environment and the second test environment by taking the second test environment as a standard, thereby realizing the alignment of the two test environments.
In practical applications, taking the test of the wake-up rate in a quiet scene with a distance of 3 meters as an example, as shown in fig. 2, the straight-line distance between the device under test 201 and the playback device 202 may be set to 3 meters. To align the first and second test environments, when arranging the first and second test environments, each may be arranged as follows: in order to test the effect of far-field equipment and avoid strong interference of reverberation, the selected room can be a room which is larger than 30 square meters, has a length of more than 6 meters and has no obvious strong reflecting surface, and the reverberation value of the room can be smaller than or equal to 0.4; the distance between the equipment to be tested and the playing equipment for playing the test audio file and the placing angle between the equipment to be tested and the playing equipment can be determined through measuring by a tape measure and a protractor, the table and the chair in a room can be placed at a fixed position, no shielding object is placed between the equipment to be tested and the playing equipment, and the equipment to be tested can be arranged to be far away from the wall surface by more than 0.5 m; the test audio file can be played by adopting a playing device, and the decibel value measured by the sound level meter at the microphone of the device to be tested is an expected value by adjusting the volume of the playing device. The sound level meter may be a calibrated sound level meter that may be tuned to dBA weighted mode FAST (FAST) sampling state.
It should be noted that, taking the device to be tested as the smart device as an example, the user may control the smart device through the voice instruction, for example, the smart device may be a smart speaker. Before the product is sold, the intelligent device needs to be tested, and the product test can identify the correctness, integrity, safety and quality of the product. Before the smart device comes to the market, the pickup test needs to be performed. Testing is required each time a product software version is updated, and multiple tests are required for each software version. The test environment of each test is not necessarily the same, and different test environments may affect the test result. For example, even if the test is performed in the same room, the environmental parameters may change due to the increase and decrease of the home in the room or the movement of the placement direction, for example, resulting in different reverberation values. In addition, in each test, even if the device under test is a mass production device of the same batch, the sound pickup parameters such as the sensitivity of the microphone are different, which results in a large difference in the test result. In the embodiment of the invention, the first test voice collected by the equipment to be tested is obtained, and the play setting parameter of the first play equipment is adjusted by using the voice signal entering the equipment to be tested, so that the influence of different test environments on the test result can be avoided, and the condition that whether the external environments of multiple tests are the same is not simply checked.

Therefore, the playing setting parameters of the first playing device can be adjusted based on the comparison result, or prompt information is output, so that the influence of different testing environments on the testing result can be avoided, and the accuracy of the testing result can be improved.
Optionally, before the obtaining of the first test voice collected by the device to be tested, the method further includes:

The second playing device may be a device with a playing function, such as a computer or a sound box, and the second playing device may be the same as the first playing device or different from the first playing device. The voice feature parameter of the second test voice may be obtained based on the magnitude of the second test voice. The position of the first playing device relative to the device under test may be the same as the position of the second playing device relative to the device under test. For example, the first playback device may be placed 1m directly in front of the device under test, and the second playback device may be placed 1m directly in front of the device under test.
In practical application, taking the second playing device as an example of a sound box, the sound box plays the test audio file, the device to be tested records, and collects the second test voice, for example, the second test voice may be a b.pcm audio file. The voice characteristic parameter of the second test voice may include a magnitude of each sampling point in the b.pcm audio file, or the voice characteristic parameter of the second test voice may be calculated based on the magnitude of each sampling point in the b.pcm audio file.
In this embodiment, a second test voice collected by a device to be tested is obtained, where the second test voice is a voice of the second playing device collected by the device to be tested playing the test audio file; acquiring voice characteristic parameters of the second test voice; and the reference voice characteristic parameter is the voice characteristic parameter of the second test voice. Like this, through comparing the pronunciation characteristic parameter of first test pronunciation and the pronunciation characteristic parameter of second test pronunciation to the adjustment the broadcast setting parameter of first playback devices can make the test environment of twice tests unanimous, avoids the different influence to the test result of test environment, thereby can improve the accuracy of test result.
Optionally, the play setting parameter includes a play volume.
In this embodiment, the playing setting parameter includes a playing volume, and the playing volume of the first playing device may be adjusted based on the comparison result, or the prompt information may be output, so that the user may adjust the playing volume of the first playing device based on the prompt information, thereby avoiding the influence of different testing environments on the testing result, and improving the accuracy of the testing result.
Optionally, the comparison result includes a ratio of the voice feature parameter of the first test voice to the reference voice feature parameter, and the adjusting the play setting parameter of the first playing device based on the comparison result includes:
if the ratio is larger than a first preset value, reducing the playing volume of the first playing device;
if the ratio is smaller than a second preset value, increasing the playing volume of the first playing device;
the first preset value is a positive number greater than or equal to 1, and the second preset value is a positive number less than or equal to 1.
The first test voice collected by the equipment to be tested for multiple times can be obtained. Taking the example that the device to be tested collects the first test voice a1.pcm audio file for the first time, if the ratio of the voice characteristic parameter of the a1.pcm audio file to the reference voice characteristic parameter is greater than a first preset value, the playing volume of the first playing device can be reduced; the device to be tested can acquire the first test voice for the second time, can acquire the first test voice A2.pcm audio file acquired by the device to be tested for the second time, and can increase the playing volume of the first playing device if the ratio of the voice characteristic parameter of the A2.pcm audio file to the reference voice characteristic parameter is smaller than a second preset value; the equipment to be tested can acquire the first test voice for the third time, and can acquire the first test voice A3.pcm audio file acquired by the equipment to be tested for the third time and compare the first test voice with the pcm audio file again. The comparison can be performed for multiple times until the ratio is less than or equal to a first preset value and greater than or equal to a second preset value.
In practical application, in order to improve the accuracy of the test result, the first preset value and the second preset value may be both 1, and the playing setting parameter of the first playing device is not adjusted until the voice characteristic parameter of the first test voice is the same as the reference voice characteristic parameter.
In this embodiment, if the ratio is greater than a first preset value, the playing volume of the first playing device is decreased; and if the ratio is smaller than a second preset value, increasing the playing volume of the first playing device. In this way, the ratio can be determined within a certain range by reducing or increasing the playing volume of the first playing device, so that the test environments of multiple tests can be consistent.

Taking n samples with amplitudes x1, x2, …, xn as an example, where n is a positive integer, the speech characteristic parameter of the first test speech may be:
