In the following embodiments, the present invention is explained by taking a television with smart voice as an example.
The invention will be further explained by the description of the embodiments with reference to the drawings.
Referring to fig. 1 to 5, as shown in the drawings, an embodiment of the present invention provides a voice wake-up and recognition automated testing method, including:
s100, voice awakening is carried out on the equipment to be tested by utilizing a voice instruction; the voice instruction comprises a wake-up voice instruction and a recognition voice instruction;
specifically, as shown in fig. 2, the method comprises the steps of:
s110, pre-recording the voice command and the interference audio; the interference audio comprises an external noise interference audio and an internal noise interference audio;
and S120, in the environment of playing the interference audio, performing voice awakening on the equipment to be tested by using the voice instruction.
In this embodiment, the voice command and the interfering audio may be prerecorded; for example, the voice "hello elfin" and "what good-looking art program" can be recorded in a quiet environment by a recording device. The audio of the ' hello elfin ' is used as the awakening audio, and the audio of the ' good-looking heddles is used as the identification audio. Recording a news program, wherein the recording time of the news program can be 1-3 minutes, and the audio is used as interference audio. And simulating noise in actual use by using the interference audio, and performing voice awakening on the equipment to be tested by using the voice instruction. It is easily understood that the disturbing audio includes external noise (referring to sounds other than sounds emitted by the smart tv).
For example, 100 pre-recorded voice commands (each voice command includes 1 wake-up audio and 1 recognition audio) and external noise interference audio are introduced into the test terminal, and internal noise audio is also introduced into the device under test. In an equipment control module of the test terminal, sound pressure and angle configuration parameters of a sound source sound box, an interference source sound box, a driving motor and equipment to be tested in quiet, internal noise and external noise scenes are respectively set according to test scenes 1-9 in a table 1. After the device control module of the test terminal finishes setting the test scene, the voice awakening and recognition tests of the quiet, internal noise and external noise scenes are sequentially carried out according to the test scenes 1-9 in the table 1.
Awakening and identification test in a quiet scene: the equipment control module sets an interference sound box and the equipment to be tested in a mute state, after the sound source sound box (sound box A, B, C) is set to test the angle and the sound pressure of scenes 1-3 in the table 1, the sound source sound box (sound box A, B, C) sequentially broadcasts 100 groups of voice instructions to test the scenes 1, 3 and 5 meters, and the visual detection system and the image comparison processing module are responsible for detecting and recording 3 groups of results.
Awakening test of internal noise scene: the equipment control module sets the interference sound box to be in a mute state, sets the device to be tested to broadcast and sets the sound source sound box (sound box A, B, C) to be the angle and the sound pressure of the test scene 4-6 in the table 1, and controls the device to be tested to broadcast the internal noise audio, then the sound source sound box (sound box A, B, C) sequentially broadcasts 100 groups of voice instructions to test the internal noise scene 1, 3 and 5 meters, and the visual detection system and the image comparison processing module are responsible for detecting and recording results.
Awakening and identifying test of external noise scene: the equipment control module sets the equipment to be tested to be in a mute state, sets the interference sound box and the sound source sound box (sound box A, B, C) to be angles and sound pressures of test scenes 7-9 in table 1, controls the interference sound box to play interference audio, then sequentially broadcasts 100 groups of voice instructions by the sound source sound box (sound box A, B, C) to test external noise scenes 1, 3 and 5 meters, and the visual detection system and the image comparison processing module are responsible for detecting and recording results.
The test results are shown in Table 1
Figure BDA0002667324610000111
S200, acquiring the awakened voice recognition interface image of the device to be tested, comparing the voice recognition interface image with a preset image for testing, and outputting a test result.
In conjunction with fig. 3 and 5, specifically, step S200 includes the steps of:
s210, acquiring awakened voice recognition interface image information of the equipment to be tested, which is acquired by using camera equipment;
s220, carrying out image character analysis on the voice recognition interface image information, and distinguishing a voice recognition character area from the voice recognition interface image;
s230, extracting characteristics of the characters in the voice recognition character area to obtain a characteristic group;
s240, comparing the feature group with image character feature data which correspondingly contain voice instructions in a preset feature database, obtaining a test result according to the feature comparison, and storing the test result in a test report.
In this embodiment, the sound source speaker plays a test voice command, and after the device to be tested responds to the wake-up and recognition voice command, the test terminal sends an acquisition command to the image acquisition module of the visual acquisition system. And after receiving the instruction, the vision acquisition system sends an acquisition signal to control a camera of the image information acquisition module, and shoots and acquires the image information of the awakening and identification picture for the television. The shot and collected image information is sent to a test terminal in a BMP file format, and an image comparison processing module of the test terminal preprocesses the collected image: firstly, performing tilt correction and color processing on an acquired image, eliminating noise points on the image and enhancing useful information of the image; secondly, analyzing the image characters: the collected image is subjected to overall analysis, the voice recognition character and the image area are distinguished, and the voice recognition character area is subjected to recognition processing; then, feature extraction: according to the preprocessing of the image and the voice recognition character processing of the image, the character thinning processing is carried out on the voice recognition character, and the number and the positions of the stroke end points and the cross points of the character are obtained and stored as the characteristic group.
And comparing the extracted feature group with image character feature data which correspondingly contain voice instructions in a preset feature database, identifying according to the comparison of the two groups of features to obtain a test result, and storing the test result in a test report of a test terminal.
In an implementation manner of this embodiment, during the test, when the vision inspection system detects that the device under test is not woken up and recognizes the voice command correctly, an image with a wake-up recognition error is saved to the test terminal, and the result is noted in the test report for reference. It is easy to understand that the fact that the terminal under test is not woken up correctly includes two cases: firstly, although a wake-up voice command is issued, the device under test does not recognize the command and does not respond correspondingly. The other is that although the device under test responds, the recognition result of the recognized voice command is wrong, for example, the character corresponding to the voice in the recognized voice command is "broadcast art program", but the recognized character is "broadcast movie".
Based on the voice wake-up automatic test method, the present invention further provides a storage medium, where one or more programs are stored, and the one or more programs can be executed by one or more processors to implement the steps in the voice wake-up automatic test method.
