The alignment of the test scenes of the two parties can be realized by aligning the sound pressure values from the awakening audio sources of the two parties to the mic position of the device to be tested and from the noise audio source to the mic position of the device to be tested, aligning the placing positions of the awakening audio sources and the noise audio sources relative to the device to be tested, aligning the background noise, reverberation, temperature and humidity and the like of the test scenes of the two parties and aligning the test scenes of the two parties. But the alignment effect can still be improved.
For example, the inventor found that when one party is likely to adjust the noise decibel value much higher than the other party, the error may be generated.
Based on the above alignment test scenario, an embodiment of the present application provides a test scenario alignment method, where one possible implementation manner is to improve accuracy of aligning a test scenario by playing a calibration audio signal of a specified frequency, then obtaining a sound pressure value of the calibration audio signal of the specified frequency in a test scenario of both parties, and adjusting alignment between the sound pressure value in a to-be-tested scenario and a sound pressure value in a reference test scenario. Another possible implementation manner is that the amplitude of the audio signal to be analyzed in the test scenes of both parties is analyzed by obtaining the amplitude of the audio signal to be analyzed including the wake-up audio signal and the noise audio signal, and the accuracy of aligning the test scenes is improved by adjusting the implementation manner that the amplitude in the test scenes is aligned with the amplitude in the reference test scenes. In addition, the two implementation modes can be combined to improve the efficiency of test scene alignment.
Referring to fig. 1, a method for aligning test scenarios is provided in an embodiment of the present application, where the method includes the following steps:
step 101: acquiring signal information in a reference test scene and a scene to be tested; wherein the signal information comprises at least one of: specifying sound pressure values and audio signals to be analyzed of the calibration audio signals with the specified frequencies in the reference test scene and the scene to be tested; the audio signals to be analyzed comprise reference audio signals obtained by recording specified audio signals in a reference test scene and audio signals to be corrected obtained by recording the specified audio signals in a scene to be tested;
in specific implementation, it should be noted that the scenario configuration of the scenario to be tested is performed with reference to the reference test scenario, for example, the scenario configuration includes but is not limited to: both sides test factors such as background noise, reverberation, temperature and humidity of a scene; the placement position of the signal information relative to the equipment for acquiring the signal information, and the like, so as to ensure the environment basis of the alignment of the test scenes of the two parties.
The calibration audio signal with the specified frequency can be, for example, a calibration audio signal with 1KHZ, and since the calibration audio signal with the specified frequency has the advantage of stability, by acquiring the sound pressure value of the calibration audio signal with the specified frequency, the error generated when the sound pressure value is acquired by the wake-up audio signal and the noise audio signal can be reduced, so that the alignment result of the test scene is more accurate.
Step 102: executing scene alignment operation according to the acquired signal information; the sound pressure value is used for aligning the sound pressures of the scene to be tested and the reference test scene, and the audio signal to be analyzed is used for aligning the amplitudes of the scene to be tested and the reference test scene.
In practice, because the signal information includes at least one of: and sound pressure values of the calibration audio signal with the specified frequency in the reference test scene and the scene to be tested and the audio signal to be analyzed. Therefore, the following will separately describe embodiments of performing the alignment operation according to the acquired signal information in step 102 by three cases:
case 1: and if the signal information comprises the audio signal to be analyzed.
Firstly, aiming at the audio signals to be analyzed, the reference audio signals obtained by recording the specified audio signals in a reference test scene and the audio signals to be corrected obtained by recording the specified audio signals in the scene to be tested are included. The designated audio signal comprises a wake-up audio signal and/or a noise audio signal, wherein the wake-up audio signal is a recorded audio signal comprising a wake-up word, for example, an audio signal of a wake-up word recorded by a human voice of a tester; the noise audio signal is an environmental noise audio signal, i.e. an audio signal not related to the test, such as a played video noise signal.
Moreover, as indicated in the foregoing, on the basis that the test scene to be tested is a test scene configured by referring to the reference test scene, when the specified audio signals are recorded in the reference test scene and the test scene, the specified audio signals need to be played at the same relative position of the respective test scenes, so as to ensure the consistency of the test scenes during recording, thereby ensuring the accuracy of alignment of the test scenes of both parties.
When the test scene alignment operation is executed, carrying out amplitude analysis on the reference audio signal and the audio signal to be corrected included in the audio signal to be analyzed; and if the amplitude analysis result shows that the amplitude difference between the amplitude of the audio signal to be corrected and the amplitude of the reference audio signal is greater than a preset threshold value, adjusting the amplitude of the audio signal to be corrected so as to enable the amplitude difference between the amplitude of the audio signal to be corrected and the amplitude of the reference audio signal to be smaller than or equal to the preset threshold value.
In a possible embodiment, when the amplitude of the audio signal to be corrected is adjusted, if the amplitude of the audio signal to be corrected is smaller than the amplitude of the reference audio signal, the playing volume of the audio signal to be corrected is increased; and if the amplitude of the audio signal to be corrected is greater than the amplitude of the reference audio signal, reducing the playing volume of the audio signal to be corrected.
For example, the volume adjustment may be performed according to a preset step, and the step for increasing the volume and the step for decreasing the volume may be the same or different. For example, when the amplitude of the audio signal to be corrected is greater than the amplitude of the reference audio signal, the playing volume of the audio signal to be corrected may be decreased according to the step length, and after the playing volume is decreased according to the step length, the playing volume may be near a critical point where the amplitudes are aligned, and after the playing volume is decreased, the amplitude of the audio signal to be corrected may be greater than the amplitude of the reference audio signal, and at this time, the playing volume of the audio signal to be corrected needs to be increased to achieve the purpose of accurately aligning the amplitudes, and at this time, the volume of the audio signal to be corrected may be.
By the amplitude adjusting mode, the amplitude of the audio signal to be corrected in the scene to be tested is adjusted to be in a state of smaller amplitude difference with the reference audio signal in the reference test scene.
The difference between the amplitude of the audio signal to be corrected and the amplitude of the reference audio signal is smaller by comparing the amplitudes of the reference audio signal and then adjusting the amplitude of the audio signal to be corrected, so that the conditions of the audio signal to be corrected acquired in the scene to be tested and the conditions of the reference audio signal acquired in the reference test scene are closer to or even consistent with each other. Therefore, the influence factors of the subsequent test result of the audio signal to be corrected in the scene to be tested and the subsequent test result of the reference audio signal in the reference test scene tend to be the same.
To more clearly understand the implementation process of the embodiment in this case, referring to fig. 2, a schematic flow chart of an implementation manner of the test scenario alignment provided in the embodiment of the present application includes:
step 201: and acquiring a reference audio signal recorded aiming at the specified audio signal in the reference test scene.
Wherein specifying the audio signal comprises: a wake-up audio signal and/or a noise audio signal.
Step 202: and acquiring an audio signal to be corrected recorded aiming at the specified audio signal in the scene to be tested.
The execution sequence of step 201 and step 202 is not limited, and it is only required to ensure that the execution of step 201 and step 202 is completed before step 203 is executed.
Step 203: and carrying out amplitude analysis on the reference audio signal and the audio to be corrected.
Step 204: and adjusting the amplitude of the audio signal to be corrected by taking the amplitude of the reference audio signal as a standard so as to minimize the difference between the amplitude of the audio signal to be corrected and the amplitude of the reference audio signal.
Case 2: if the signal information comprises the sound pressure value.
Firstly, when the operation of obtaining signal information in a reference test scene and a scene to be tested is executed, obtaining a sound pressure value of a calibration audio signal with specified frequency played at a specified position in the reference test scene; acquiring a sound pressure value of the calibration audio signal with the specified frequency played at the specified position in the scene to be tested; wherein the specified position refers to the relative position relation between the calibration audio signal with the specified frequency and the device to be tested. Referring to table 1 below, an example of sound pressure values in a reference test scenario and a scenario to be tested is as follows:
TABLE 1
| Reference test scenario | Scene to be tested |
| 65dB | 60dB |
As shown in table 1, for example, the sound pressure value acquired to the reference test scene is 65dB, and the sound pressure value acquired to the test scene is 60 dB.
In the sound pressure value example based on table 1, when a scene alignment operation is performed, the sound pressure value of the scene to be tested is adjusted so that the sound pressure difference between the sound pressure value of the scene to be tested and the sound pressure value of the reference test scene is smaller than a preset sound pressure difference. Assuming that the preset sound pressure difference is 0.2dB (the sound pressure difference is as small as possible, which is not limited herein), the playing volume in the scene to be tested is adjusted to increase the corresponding sound pressure value, so that the sound pressure value is infinitely close to 65 dB.
Case 3: and if the signal information comprises the sound pressure value and the audio signal to be analyzed.
When scene alignment operation is executed, determining a sound pressure difference between a sound pressure value of the reference test scene and a sound pressure value of the scene to be tested; if the acoustic pressure difference is determined to meet the amplitude adjustment condition, carrying out amplitude analysis on the reference audio signal and the audio signal to be corrected; and if the amplitude analysis result shows that the amplitude difference between the amplitude of the audio signal to be corrected and the amplitude of the reference audio signal is greater than a preset threshold value, adjusting the amplitude of the audio signal to be corrected so as to enable the amplitude difference between the amplitude of the audio signal to be corrected and the amplitude of the reference audio signal to be smaller than or equal to the preset threshold value.
In the method, if the sound pressure difference is greater than the specified threshold, it is determined that the amplitude adjustment condition is satisfied, and in this case, it is difficult to obtain an effect of aligning the test scene more accurately by adjusting the sound pressure value in the to-be-tested scene as in case 2 according to the test experience, so that the amplitude analysis is performed on the reference test scene and the to-be-tested scene through the implementation manner in case 1, and then the purpose of aligning the to-be-tested scene with the reference test scene is achieved by adjusting the amplitude.
If the sound pressure difference is smaller than or equal to the specified threshold, trying to adjust the sound pressure value of the scene to be tested so that the sound pressure difference between the sound pressure value of the scene to be tested and the sound pressure value of the reference test scene is smaller than a preset sound pressure difference; if the sound pressure difference between the sound pressure value of the scene to be tested and the sound pressure value of the reference test scene cannot be made smaller than the preset sound pressure difference, determining that the amplitude adjustment condition is met; otherwise, if the sound pressure difference between the sound pressure value of the scene to be tested and the sound pressure value of the reference test scene is smaller than the preset sound pressure difference after the sound pressure value of the scene to be tested is determined to be adjusted, determining that the amplitude adjustment condition is not met.
In this case, firstly, the sound pressure value in the scene to be tested is adjusted for the reference test scene and the scene to be tested, if the sound pressure adjustment fails to reach the preset sound pressure threshold, it indicates that a better alignment result cannot be obtained only through the sound pressure adjustment, then the amplitude values of the test scenes of both parties are further adjusted according to the implementation mode in the case 1, so that the accuracy of the test scenes of both parties is improved. On the contrary, if a better alignment result is obtained by adjusting the sound pressure, the amplitude analysis is not needed.
In addition, it should be noted that, when performing amplitude analysis on the reference audio signal and the audio signal to be corrected, in order to obtain a better amplitude adjustment effect, in a possible implementation manner, a specified audio signal segment corresponding to the reference audio signal and the audio signal to be corrected is taken to perform amplitude analysis.
Wherein the specified audio signal segment comprises one of:
the designated audio segment is a wake-up audio signal recording segment, for example, a noise audio signal in the designated audio signal at this time is almost absent, and a relatively ideal test result can be obtained.
The designated audio segment is a noise audio signal recording segment, for example, at this time, there is no wake-up audio signal, and by this segment, the influence of the noise audio signal on the alignment of the test scene can be analyzed.
The designated audio segment is a segment in which a wake-up audio signal and a noise audio signal are recorded together, for example, this is a general case in the designated audio segment, and belongs to a segment of the designated audio signal that is relatively in line with the condition of the test scenario.
When amplitude analysis is carried out, the specified audio signals which are well analyzed can be selected to be segmented according to requirements, and therefore the alignment effect of the test scenes of the two parties is improved.
By the method for testing scene alignment, the effect of aligning the scene to be tested with the reference test scene can be achieved. Therefore, when the factors influencing the audio signals in the reference test scene are analyzed, because the reference test scene is not an environment in which the test can be carried out at any time, the influence factors can be analyzed by carrying out the test in the scene to be tested, and the influence factors in the reference test scene are reversely deduced. Therefore, by the method, convenient and accurate test conditions are provided for solving the problems encountered in the reference test scene.
