[0040] As Figure 1 shown, the voice interaction test system of the sound pickup device provided by the embodiments of the present application comprises a detection platform 1, a voice player 2 and an angle adjusting device 3. The detection platform 1 is used for placing a sample machine to be tested 4. The voice player 2 is arranged on one side of the detection platform 1 and is arranged in a spaced manner with the detection platform 1. The driving end of the angle adjusting device 3 is connected with the detection platform 1, and is used for adjusting the angle of the detection platform 1 relative to the voice player 2.

[0041] The distance between the detection table 1 and the voice player 2 is adjusted or calibrated according to test requirements.

[0044] As shown in Figure 1 The voice interaction test system of the sound pickup device provided in the embodiment of the utility model further includes a sliding rail 5. At least one of the detection table 1 and the voice player 2 is slidingly arranged on the sliding rail 5, so that the detection table 1 and the voice player 2 can approach or move away from each other.

[0045] Specifically, the sliding rail 5 is used to be installed on the ground or the table top and is arranged to extend between the detection table 1 and the voice player 2. The detection table 1 or the voice player 2 can be slidingly arranged on the sliding rail 5, or the detection table 1 and the voice player 2 can be slidingly arranged on the sliding rail 5. At least one of the detection table 1 and the voice player 2 moves along the sliding rail 5, the distance between the detection table 1 and the voice player 2 is adjusted, and the voice interaction test under different distances is realized.

[0048] Specifically, when the testing platform 1 is slidably mounted on the slide rail 5 and the position of the voice player 2 relative to the slide rail 5 remains unchanged, the driving component is connected to the testing platform 1 and is used to drive the testing platform 1 to move along the slide rail 5, thereby adjusting the distance between the testing platform 1 and the voice player 2.

[0049] When the voice player 2 is slidably positioned on the slide rail 5 and the position of the detection platform 1 relative to the slide rail 5 remains unchanged, the drive component is connected to the voice player 2 and is used to drive the voice player 2 to move along the slide rail 5, thereby adjusting the distance between the detection platform 1 and the voice player 2.

[0052] Specifically, the testing platform 1 is horizontally positioned, with its upper surface supporting the sample to be tested and its lower surface connected to the driving end of the first driving member 31. The driving end of the first driving member 31 rotates around a vertical axis, thereby driving the testing platform 1 to rotate around the vertical axis, i.e., adjusting the azimuth angle of the testing platform 1. The rotation axis of the driving end of the second driving member 32 is set in the horizontal direction, thereby driving the first driving member 31 to rotate around a horizontal axis, which in turn drives the testing platform 1 to rotate around the horizontal axis, i.e., adjusting the pitch angle of the testing platform 1.

[0053] The pickup device voice interaction test system provided in the embodiment of the utility model further comprises a controller (not shown in the figure). The first driving part 31 and the second driving part 32 are both stepping motors, and the first driving part 31 and the second driving part 32 are electrically connected with the controller. In the embodiment, the detection table 1 is driven to rotate by the stepping motor, and the stepping motor is controlled by the controller, so that the azimuth angle and the pitch angle of the detection table 1 can be accurately adjusted, and the accuracy of test data is improved.

[0054] As shown in Figure 1 The pickup device voice interaction test system provided in the embodiment of the utility model further comprises a first height adjusting device 6 and / or a second height adjusting device 7. The angle adjusting device 3 is connected to the first height adjusting device 6, and the first height adjusting device 6 is used for adjusting the height of the detection table 1 relative to the voice player 2. The voice player 2 is connected to the second height adjusting device 7, and the second height adjusting device 7 is used for adjusting the height of the voice player 2 relative to the detection table 1.

[0055] When the pickup device is subjected to voice interaction test, the height of the detection table 1 can be adjusted by the first height adjusting device 6, and / or the height of the voice player 2 can be adjusted by the second height adjusting device 7, so that the to-be-tested sample machine 4 on the detection table 1 and the voice player 2 are at the same height. In the case of the same height, the to-be-tested sample machine 4 is subjected to voice interaction test at different azimuth angles and different pitch angles.

[0056] In some embodiments of the utility model, the first height adjusting device 6 comprises a fixed rod, a movable rod and a locking part. One end of the movable rod is movably inserted into the fixed rod, and the other end of the movable rod is connected to the angle adjusting device 3. The locking part is arranged on the side wall of the fixed rod and is used for locking the fixed rod and the movable rod.

[0057] It can be understood that the first height adjusting device 6 is a telescopic rod structure. The locking part can be a screw or a bolt, and the locking part is threadedly connected with the fixed rod. When it is necessary to adjust the height of the detection table 1, the locking part is loosened, the telescopic length of the movable rod relative to the fixed rod is adjusted according to the requirement, and then the locking part is tightened to abut against the movable rod, so as to lock the fixed rod and the movable rod.

[0058] In some embodiments of the utility model, the angle adjusting device 3 is a spherical tripod head locking structure. The bottom of the detection table 1 and the other end of the movable rod are rotationally connected and locked by the locking mechanism, forming a spherical tripod head locking structure. The spherical tripod head locking structure can adjust the spatial angle of the detection table 1. For example, the azimuth angle on the horizontal plane and the pitch angle on the vertical plane.

[0059] Specifically, the bottom of the testing platform 1 is provided with a connecting part, and the end of the connecting part is a spherical structure. The end of the movable rod is provided with a spherical cavity, and the spherical structure of the connecting part is rotatably disposed in the spherical cavity of the movable rod. The spatial angle of the testing platform 1 is adjusted by rotating the spherical structure in the spherical cavity. The locking mechanism includes a locking member and a locking device. The spherical structure is locked by the locking member located in the spherical cavity and the locking device connected between the locking member and the spherical cavity. The spherical gimbal locking structure is a conventional gimbal angle adjustment mechanism, which will not be described in detail in this embodiment.

[0060] The structures of the first height adjustment device 6 and the second height adjustment device 7 can be the same or different.

[0061] like Figure 5 As shown, in some embodiments of this utility model, the second height adjustment device 7 includes a placement platform 71 and multiple scissor telescopic mechanisms 72. The placement platform 71 is used to place the voice player 2, and the telescopic ends of the multiple scissor telescopic mechanisms 72 are connected to the placement platform 71.

[0062] The placement platform 71 is horizontally positioned, with its upper surface supporting the voice player 2 and its lower surface connected to the telescopic end of the scissor-lift telescopic mechanism 72. Multiple scissor-lift telescopic mechanisms 72 can extend and retract synchronously under the action of a driving component. Each scissor-lift telescopic mechanism 72 consists of multiple rods that are cross-hinged in the longitudinal and transverse directions, forming a stable frame structure that maintains good stability during extension and retraction. This scissor-lift telescopic mechanism 72 is a conventional telescopic structure, and will not be described in detail in this embodiment.

[0063] In this embodiment, the voice player 2 can be an artificial mouth or a speaker. Since the speaker is relatively heavy and bulky, multiple scissor-telescopic mechanisms 72 can be used to stably support and adjust its height.

[0064] Furthermore, the slide rail 5 is provided with a first slider 51 and a second slider 52. The detection platform 1 is slidably mounted on the slide rail 5 via the first slider 51, and the voice player 2 is slidably mounted on the slide rail 5 via the second slider 52.

[0065] In one specific embodiment, the voice interaction testing system for the sound pickup device includes a first height adjustment device 6 and a second height adjustment device 7. Angle adjustment device 3 is connected to a first slider 51 via the first height adjustment device 6. Voice player 2 is connected to a second slider 52 via the second height adjustment device 7.

[0066] like Figure 2 As shown, in some embodiments of this utility model, the testing platform 1 is provided with multiple mounting holes, and the sample to be tested 4 is installed and fixed to the testing platform 1 by fasteners passing through the mounting holes.

[0067] In the case that the to-be-tested sample machine 4 is a space type sound pickup device, since the space type sound pickup device is usually used to be installed on the ceiling, the space type sound pickup device itself is provided with mounting holes 41. When the voice interaction test is performed, at least two mounting holes 41 of the space type sound pickup device are matched with two mounting holes on the detection table 1, and the space type sound pickup device is fixedly connected with the detection table 1 through the fixing member, so as to facilitate the adjustment of the pitch angle of the detection table 1.

[0068] In a specific embodiment of the utility model, as shown in the figure, Figure 1 The first height adjusting device 6 is installed on the first sliding block 51. The voice player 2 is installed on the second sliding block 52 through the second height adjusting device 7. The angle adjusting device 3 is connected between the first height adjusting device 6 and the detection table 1, and is used to adjust the azimuth angle and the pitch angle of the detection table 1 relative to the voice player 2.

[0069] On the basis of the above-mentioned embodiment, the sound test device voice interaction test provided in the embodiment further comprises a plurality of environmental sound players, such as sound boxes. During the test, the sound pickup device voice interaction test system is arranged in the center of the test environment, and a plurality of environmental sound players are arranged around, which are used to play environmental noise.

[0070] The sound pickup device voice interaction test system of the embodiment can be used for sound source positioning test, sound test angle range test and transcription rate test of the to-be-tested sample machine 4. During the test, the to-be-tested sample machine 4 and the voice player 2 are adjusted to the same height through the first height adjusting device 6 and / or the second height adjusting device 7. The to-be-tested sample machine 4 and the voice player 2 are adjusted to the set distance through the adjustment of the first sliding block 51 and / or the second sliding block 52. The corpus is played through the voice player 2, and the volume size is calibrated according to the test requirements.

[0071] During the sound source positioning test, first, the azimuth angle of the to-be-tested sample machine 4 relative to the voice player 2 is adjusted to an initial angle. The sound source positioning effect of the to-be-tested sample machine 4 at the initial angle is tested. Then, the azimuth angle of the to-be-tested sample machine 4 relative to the voice player 2 is adjusted through the angle adjusting device 3, which is +10°, +20°, +30°, +40°, +50°……+350° based on the initial angle, and the sound source positioning effect at each angle is tested in turn. After all the angles are traversed, the sound source positioning effect of the to-be-tested sample machine 4 is obtained. Further, the distance between the to-be-tested sample machine 4 and the voice player 2 can be adjusted, and then the above steps are repeated to obtain the sound source positioning effect of the to-be-tested sample machine 4 at different distances.

[0072] When testing the pickup angle range, the initial angle is first adjusted to the pitch angle of the test sample 4 relative to the voice player 2. This initial angle is set with the pickup end of the test sample 4 pointing towards the voice player 2, and the normal direction of the pickup end being horizontal. (See [reference]). Figure 2 The x-axis direction is used. According to the established sound pickup standard, the sound pickup effect of the test prototype 4 in the positive x-axis direction is tested. Then, the pitch angle of the test prototype 4 relative to the voice player 2 is adjusted sequentially using the angle adjustment device 3, from the initial angle by +10°, +20°, +30°, ..., +90° and -10°, -20°, -30°, ..., -90°, to complete the sound pickup effect at each angle. After traversing all angles, the sound pickup angle range of the test prototype 4 is obtained. Furthermore, the distance between the test prototype 4 and the voice player 2 can be adjusted, and the above steps can be repeated to obtain the sound pickup angle range of the test prototype 4 at different distances.

[0073] During the transcription rate test, the relative positions of the sound source and the test sample 4 are adjusted to a specific angle using the angle adjustment device 3 according to the actual usage scenario. The test sample 4 picks up the audio and transcribes it. The transcribed document is compared with the standard corpus document, and the transcription rate result is output.
